Wisdom Teeth

In most people, the third set of molars, generally called “wisdom teeth,” start coming in around age 17-25. However, the arrival of these teeth is often far from trouble-free. The extraction (removal) of one or more third molars is a relatively common procedure, performed on some 5 million patients every year. After a thorough examination and diagnostic tests such as x-rays or a CT scan, you may be told that you should have your wisdom teeth extracted. Here are some typical reasons why:

  • Your jaw may be too small to accommodate all your teeth, leading to excessive crowding and the chance of your wisdom teeth becoming impacted — that is, unable to emerge from the gums, and potentially harmful to adjacent bone or teeth
  • Your wisdom teeth may be erupting (coming in) in a crooked orientation, which can damage other teeth or anatomical structures in the jaw, and/or cause bite problems
  • If your wisdom tooth does not fully erupt (emerge from the gums), it can increase the chance for bacterial infection
  • A cyst (a closed, fluid-filled sac) may develop around the unerupted wisdom tooth, which can cause infection and injury to the adjacent bone or nerve tissue

Whether it is aimed at preventing future problems or needed to alleviate a condition you already have, the extraction of wisdom teeth can be an effective treatment. But, as with all medical procedures, its benefits must be weighed against the small risk of complications, and should be discussed in detail.

The Extraction Procedure

Wisdom tooth extraction is usually an in-office procedure which may be performed by a dentist or an oral surgeon. It’s quite possible to have the treatment done with only a local anesthetic (numbing shot) to keep you from experiencing any pain; however, if multiple teeth are being extracted at one time (as is often the case), a general anesthetic or conscious sedation may be administered. The type of anesthesia that’s best for you will be determined before the procedure.

Once you have been appropriately anesthetized, the gum tissue at the extraction site may need to be opened if the tooth is impacted. The tooth itself will then be gently removed. When the extraction is complete, you may need to have the site sutured (stitched) to aid healing. After the procedure is over, you will rest for a short time before going home. Depending on what type of anesthesia you have had, you may need another person to drive.

After the Procedure

The recovery period after wisdom tooth extraction generally lasts only a few days. During this time, you should rest when possible to encourage healing, and take any pain medication as prescribed. It’s normal to experience some bleeding at the extraction site; this can be controlled by gently biting on gauze pads, changing them as needed, and resting with the head elevated on pillows rather than flat.

Holding an ice pack on the outside of your cheek for a few minutes at a time (for example, 5 minutes on / 5 minutes off) may help reduce swelling on the first day after the procedure. Starting on day 2, the warm moist heat of a washcloth placed on the cheek may make you more comfortable. Rinsing the mouth with warm salt water a few times a day can also help relieve discomfort.

You may want to eat soft foods for a few days after the extraction; likewise, be careful when brushing or putting anything in your mouth until your healing is complete. Be sure to follow the postoperative instructions you are given, as each situation is a little different; this will help you to be as comfortable as possible.

Space Maintainers

Your child’s little baby teeth have some big responsibilities. Until the adolescent years, they will not only help your youngster bite and chew (i.e., get proper nutrition) and speak correctly but also help guide the permanent teeth underneath them into proper position. In fact, a major function of baby teeth is to hold space for the adult teeth that will eventually push them out.

At least that’s how it’s supposed to work; sometimes, however, injury or disease can cause a baby tooth to be lost prematurely. When that happens, the permanent teeth that are coming in on either side can actually drift into the space that was reserved for another tooth. This can cause teeth to erupt out of position or to be blocked entirely, and it may result in crowded or crooked teeth.

Fortunately, if your child loses a tooth prematurely, there’s a dental appliance that can be used to hold the space open for the permanent tooth that is meant to fill it. The device is, not surprisingly, called a “space maintainer” or a “space maintenance appliance.” Made of metal and/or plastic, space maintainers can be fixed (cemented) or removable, but either way their purpose is the same: to help your child develop the best bite possible and hopefully avoid the need for braces later on.

Fixed appliances are cemented onto adjacent teeth. They are made in many different designs: One consists of a band that goes around a tooth and then a wire loop that extends out from the band to hold the space; another features a loop attached to a stainless steel crown, which goes over a nearby tooth. In either case, the loop extends just to the point where it touches the next tooth. Fixed space maintainers are often preferred with younger children, because they are less easy to fidget with, break, or misplace than appliances that can be removed.

Removable appliances look like the type of retainer that is worn at the end of orthodontic treatment. It can have a false tooth on it, which is particularly useful when the lost tooth was visible in the mouth. Older children can usually handle the responsibility of wearing this appliance and caring for it properly.

Whether fixed or removable, your child’s space maintainer will be custom-made after we take impressions of his or her mouth. A child will wear a space maintainer until x-rays reveal that the tooth underneath is ready to erupt naturally. It is very important that anyone wearing a space maintainer keep up good oral hygiene at home and have regular professional dental cleanings.

Space maintainers are also useful when one or more permanent teeth are congenitally missing — in other words, they have never existed at all. In cases like this, which are not uncommon, permanent dental implant teeth are often recommended for adolescents or adults to replace a tooth they weren’t born with. But timing is very important with dental implants — they can’t be placed in a growing child. Therefore, it is very important to use a space maintainer with a false tooth on it until jaw growth is complete and an implant can be appropriately placed. It’s a simple, non-invasive way we can avoid a malocclusion (bad bite) with some timely intervention.

Laser Dentistry

They are inside your laptop computer and your DVD player, present on the factory floor and the supermarket checkout line. And now, lasers are finding increasing use in dentistry. Someday soon, you may have a routine dental procedure performed with the aid of a powerful, yet highly controllable beam of laser light, instead of a drill or a probe.

What are dentists currently using lasers for? These devices have been proven to help in the detection and treatment of oral diseases. They can be used for treating gum disease, detecting cancer, and pinpointing tooth decay in its early stages. They can precisely remove tissue, seal painful ulcerations like canker sores, and even treat small cavities. In the future, dental laser technology will undoubtedly find even more applications.

How Do Lasers Work?

Lasers take advantage of the quantum behavior of electrons, tiny particles inside atoms. By stimulating atoms with pulses of energy, and then using a method of optical amplification, they cause the atoms to produce a beam of coherent light. Essentially, that means that they emit light which has a great deal of energy, yet can be precisely controlled. It’s the combination of high energy and precision that make lasers so useful.

Where Are Lasers Being Used?

At present, the use of lasers in dentistry falls into three general categories: disease detection, soft tissue treatments, and hard tissue treatments.

There are many ways lasers can aid in diagnosis. Laser light of specific wavelength, for example, can detect tiny pits and fissures in the biting surfaces of the tooth that a traditional dental tool can’t find. This enables a defect that’s too small to be treated at present to be carefully monitored. Lasers can also help locate dental calculus (tartar) beneath the surface of the gums, and can even aid in the detection of oral cancer in its early stages, accurately showing where healthy tissue ends and diseased tissue begins.

For the treatment of soft tissue problems, lasers have many advantages. They are minimally invasive tools that generally involve taking away less tissue than conventional methods. Used in gum surgery, for example, lasers can treat gum disease by killing harmful bacteria deep in pockets below the gum line, and removing the diseased tissue without harming the healthy tissue. They can also remove the thin layer of cells that inhibits reattachment of the gum and bone tissues to the tooth, while sealing off the adjacent blood vessels. This type of procedure generally results in less bleeding and pain. Lasers are also effective in treating ulcers and sores on the lips or gums.

Lasers are even finding increasing use for hard-tissue procedures, like the treatment of dental caries and cavities. Not only are they more exact in the amount of material they remove, but they eliminate the noise and vibration of the dental drill, which is uncomfortable for some patients.

As lasers become more common in the dental office, these high-tech tools will be integrated into routine dental practice. This promising technology already offers some real benefits, and is sure to find increasing use in the near future.

Toothpaste

Toothpaste: It’s something most people use every day, but rarely give much thought to — except, perhaps, when choosing from among the dozens of brands that line the drugstore shelf. Is there any difference between them? What’s toothpaste made of… and does it really do what it promises on the box? To answer those questions, let’s take a closer look inside the tube.

The soft, slightly grainy paste that you squeeze on your brush is the latest in a long line of tooth-cleaning substances whose first recorded use was around the time of the ancient Egyptians. Those early mixtures had ingredients like crushed bones, pumice and ashes — but you won’t find that any more. Modern toothpastes have evolved into an effective means of cleaning teeth and preventing decay. Today, most have a similar set of active ingredients, including:

  • Abrasives, which help remove surface deposits and stains from teeth, and make the mechanical action of brushing more effective. They typically include gentle cleaning and polishing agents like hydrated silica or alumina, calcium carbonate or dicalcium phosphate.
  • Detergents, such as sodium lauryl sulfate, which produce the bubbly foam you may notice when brushing vigorously. They help to break up and dissolve substances that would normally be hard to wash away, just like they do in the laundry — but with far milder ingredients.
  • Fluoride, the vital tooth-protective ingredient in toothpaste. Whether it shows up as sodium fluoride, stannous fluoride or sodium monofluorophosphate (MFP), fluoride has been conclusively proven to help strengthen tooth enamel and prevent decay.

Besides their active ingredients, most toothpastes also contain preservatives, binders, and flavorings — without which they would tend to dry out, separate… or taste awful. In addition, some specialty toothpastes have additional ingredients for therapeutic purposes.

  • Whitening toothpastes generally contain special abrasives or enzymes designed to help remove stains on the tooth’s surfaces. Whether or not they will work for you depends on why your teeth aren’t white in the first place: If it’s an extrinsic (surface) stain, they can be effective; however, they probably won’t help with intrinsic (internal) discoloration, which may require a professional whitening treatment.
  • Toothpastes for sensitive teeth often include ingredients like potassium nitrate or strontium chloride, which can block sensations of pain. Teeth may become sensitive when dentin (the material within the tooth, which is normally covered by enamel, or by the gums) becomes exposed in the mouth. These ingredients can make brushing less painful, but it may take a few weeks until you really notice their effects.

What’s the best way to choose a toothpaste? The main thing you should look for is the American Dental Association (ADA) Seal of Acceptance on the label. It means that the toothpaste contains fluoride — and that the manufacturer’s other claims have been independently tested and verified.

But once you’ve chosen your favorite, keep this bit of dental wisdom in mind: It’s not the brush (or the paste) that keeps your mouth healthy — it’s the hand that holds it. Don’t forget that regular brushing is one of the best ways to prevent tooth decay and maintain good oral hygiene.

Top Reasons To Choose Dental Implants

The dental implant is today’s state-of-the-art tooth replacement method. It consists of a very small titanium post (the actual implant), which is attached to a lifelike dental crown. The crown is the only part of this tooth-replacement system that is visible in your mouth. The implant itself rests beneath your gum line in the bony socket that used to hold your missing tooth. Two, four or more implants can be used to support multiple crowns, or even an entire arch of upper or lower replacement teeth. Whether you are missing one tooth, several teeth or all your teeth, dental implants are preferred by doctors and patients alike. That’s because dental implants are:

Most Like Natural Teeth

Your natural teeth have roots that keep them securely anchored to your jawbone. In a similar way, implant teeth form a solid attachment with the bone in your jaw. This is possible because dental implants are made of titanium, a metal that has a unique ability to fuse to living bone. After an implant is inserted during a minor procedure done in the dental office, it will become solidly fused to your bone over a period of several months. Once that happens, your implant-supported replacement tooth (or teeth) will feel completely natural. It will also be visually indistinguishable from your natural teeth. Implant teeth allow you to eat, speak and smile with complete confidence because they will never slip or shift like removable dentures often do.

The Longest-Lasting Tooth Replacements

Because dental implants actually become part of your jawbone, they provide a permanent solution to tooth loss. Whereas other methods of tooth replacement, including removable dentures and bridgework, may need to be replaced or remade over time, properly cared-for dental implants should last a lifetime. That’s what makes this choice of tooth replacement the best long-term value.

Able To Prevent Bone Loss

You may not know it, but bone loss inevitably follows tooth loss. Bone is a living tissue that needs constant stimulation to rebuild itself and stay healthy. In the case of your jawbone, that stimulation comes from the teeth. When even one tooth is lost, the bone beneath it begins to resorb, or melt away. This can give your face a prematurely aged appearance and even leave your jaw more vulnerable to fractures if left untreated long enough (View Example). Dental implants halt this process by fusing to the jawbone and stabilizing it. No other tooth replacement method can offer this advantage.

Safe For Adjacent Natural Teeth

Dental implants have no effect on the health of adjacent natural teeth; other tooth-replacement systems, however, can weaken adjacent teeth. With bridgework, for example, the natural teeth on either side of a gap left by a missing tooth must provide support for the dental bridge. This can stress those adjacent teeth and leave them more susceptible to decay. Likewise, a partial denture relies on adjacent natural teeth for support and may cause those teeth to loosen over time. Dental implants are stand-alone tooth replacements that don’t rely on support from adjacent natural teeth.

Easy To Care For

Caring for implant teeth is no different than caring for your natural teeth. You must brush them and floss them daily. But you’ll never have to apply special creams and adhesives, or soak them in a glass overnight, as you would with dentures. They’ll also never need a filling or a root canal, as the natural teeth supporting bridgework might. While implants can never decay, they can be compromised by gum disease. Good oral hygiene and regular visits to the dental office for professional cleanings and exams is the best way to prevent gum disease, and to ensure your dental implants last a lifetime, as they’re designed to do.

Two Types of Periodontal Disease

Gingivitis is a chronic bacterial infection. It occurs when plaque builds up around a tooth and creates a sticky layer which causes inflammation of the gum tissue. You may see redness, swelling and bleeding of the gum around your tooth.

Periodontitis is also a chronic bacterial infection. It occurs in susceptible patients when a long-term gum infection is not treated. Infection and resultant inflammation lead to the loss of ligaments and bone around the root of your tooth making a deep pocket. Factors which significantly increase the risk of developing periodontitis include:

  • Genetics
  • Smoking
  • Diabetes
  • Medications (certain anti-seizure, blood pressure, and immunosuppressant medications)
  • Stress
  • Poor Oral Hygiene

Prophy/cleanings

Prophy appointments help prevent or reverse gingivitis, (infection and inflammation of the gums around the neck of the tooth), by removing plaque and mineralized plaque or tartar/calculus on the teeth. A Prophy is typically recommended every six months to help keep you healthy.

Periodontal maintenance

Periodontal maintenance appointments take the place of a prophy after you have had treatment for periodontitis, (infection that deteriorates the gums and bone around the root of the tooth). These appointments can be more frequent than a regular prophy to help keep periodontitis stable. These maintenance visits disrupt disease causing bacteria below the gumline by removing plaque and tarter above and below the gumline.

Non-Surgical Periodontal Therapy

The goal of non-surgical periodontal therapy is to stop active infection and establish a healthy environment below the gumline. Your hygienist does this by removing tartar/calculus in the periodontal pocket which reduces the microbial load and toxins. It may require more than one appointment.

Materials used during Non-Surgical Periodontal Therapy

The following materials and techniques may be used in your nonsurgical periodontal therapy:

  • Hand held instruments known as scalers and ultrasonics to clean the teeth.
  • Local anesthetic (numbing) to control sensitivity.
  • Antibacterial rinses to help decrease plaque and calculus.
  • Antibiotic pills to help kill bacteria and viruses and reduce the destructive response some people have to periodontal infections.
  • Laser treatment to control bacterial levels around affected areas.

Benefits of Non-Surgical Periodontal Therapy

Some potential benefits of non-surgical periodontal therapy include:

  • Eliminating the infection present
  • Controlling further infections and bone loss
  • Reducing swollen and bleeding gums
  • Reducing bad breath
  • Avoiding tooth loss
  • Decreasing the risk for diseases associated with periodontal disease such as cardiovascular disease, diabetes and rheumatoid arthritis
  • Decreasing the risk of preterm low birth weight babies in pregnant women

Health Implications of Deep Dental Pockets

While tooth loss is typically the biggest concern associated with periodontal pockets, the infection poses a significant risk to your overall health. Active gum disease drastically increases the risk and severity of systemic health conditions like:

  • Heart attack
  • Stroke
  • High blood pressure
  • Diabetes
  • Infertility
  • Erectile dysfunction
  • Preeclampsia
  • Pneumonia
  • Respiratory illness
  • Alzheimer’s Disease (possibly)

Seeing a dentist for periodontal treatment isn’t just important for your smile, it’s vital to your health.

 

Temporary Anchorage Devices (TADS)

Every so often, in dentistry and other fields, a new technology comes along that promises to change the standard practices. TADS (Temporary Anchorage Devices) aren’t exactly new — orthodontists have used them since the 1980s — but they’re gaining widespread acceptance today. The benefits they offer some orthodontic patients could even be called groundbreaking. Let’s look at what these devices are, and what they can do.

Essentially, TADS are small, screw-like dental implants made of a titanium alloy. As the name implies, they’re temporary — they usually remain in place during some months of treatment, and then they are removed. Their function is to provide a stable anchorage — that is, a fixed point around which other things (namely, teeth) can be moved. But why is anchorage so important?

Moving teeth in the jaw has been compared to moving a stick through the sand. With the application of force, sand moves aside in front of the stick, and fills up the space behind. The “sand” in this case consists of bone cells and cells of the periodontal ligament, which attaches the tooth to the bone. These tissues slowly move aside and reform as force is applied to them by orthodontic appliances, such as wires and elastics.

But to do its work, that force needs a fixed point to push against. For example, imagine trying to move the stick while you’re floating free in the water: Not so easy! But with two feet firmly planted in the sand, you can do it. When possible, orthodontists use the back teeth as an anchor — but sometimes, cumbersome headgear may be required to provide the necessary anchorage. In many cases, using TADS can change that.

What TADS Can Do

While it’s generally preferred, the use of teeth as orthodontic anchors can have drawbacks in some cases. For example, there may not be a viable tooth located at the point where an anchor is needed. Also, when a greater force is required, the teeth used as anchors can themselves start to move. This is one instance where TADS are beneficial: These mini-implants can eliminate the need to use teeth as anchors, or stabilize a tooth that’s being used as such.

TADS can also provide an anchorage point for a pushing or pulling force that would otherwise need to be applied from outside the mouth: generally, via orthodontic headgear. Wearing headgear can be uncomfortable, and compliance is sometimes a problem. In many situations TADS can eliminate the need for headgear, a welcome development for many patients.

The use of TADS offers other benefits as well: It may shorten overall treatment time, eliminate the need to wear elastics (rubber bands) — and in some cases, even make certain oral surgeries unnecessary. It also allows orthodontists to take on complex cases, which might formerly have proved very difficult to treat. This small device can really do a big job!

Getting (and Maintaining) TADS

Like dental implants (which have been in use since the 1970s) TADS are small, screw-like devices that are placed into the bone of the jaw. Unlike implants, however, they don’t always need to become integrated with the bone itself: They can be fixed in place by mechanical forces alone. Plus, they’re much easier to put in and remove when treatment is complete. How easy?

Placing and removing TADS is a minimally-invasive, pain-free procedure. After the area being treated is numbed (with an injection or other numbing treatment), a patient feels only gentle pressure as the device is inserted. The whole process can take just minutes to complete. Afterwards, an over-the-counter pain reliever can be taken if needed — but many patients need no pain reliever at all. And taking TADS out is even easier. So if you’re worried that it may be a painful procedure: Relax! It’s far less stressful than you may think.

While they’re in place, TADS require minimal maintenance. Generally, they should be brushed twice daily with a soft toothbrush dipped in an antimicrobial solution. You will receive specific instructions regarding maintenance when your TADS are placed.

Not every orthodontic patient needs TADS — but for those who do, it’s a treatment option that offers some clear benefits.

Headaches & Migraines

People don’t generally think of a dentist as the healthcare professional to see for recurring headaches or migraines; yet dentists can play a role in diagnosing and even treating your condition. That’s because quite often, recurring pain that is felt in the area of the temples on the sides of the head is actually caused by unconscious habits of clenching and/or grinding the teeth. These habits, which often manifest during sleep, put tremendous pressure on the muscles that work your jaw joint, also called the temporomandibular joint (TMJ).

The fan-shaped temporalis muscles located over your temples on either side of your head are two of several muscles involved in jaw movement. You can easily feel them working if you put your fingertips on your temples while clenching and unclenching your jaw. When temporalis muscles go into spasm from too much clenching, headache symptoms may result. This is not to say that headaches and migraines are always caused by TMJ problems, also known as temporomandibular disorders (TMD). But given the established link between them, it definitely bears looking into — especially if a diagnosis remains elusive in your case.

Sources of Relief

Custom-Made Nightguard.

Nightguard Migrane Relief

The first thing you need is a thorough oral exam to determine if there is evidence of a clenching or grinding (also known as “bruxing”) habit or TMD. If so, there are things you can do for immediate and long-term relief. Sometimes eating softer foods for a few days can reduce stress on the muscles and joints. Ice and/or moist heat can help relieve soreness and inflammation. Gentle stretching exercises, non-steroidal anti-inflammatory medications such as ibuprofen, and muscle relaxants can also provide relief.

Finally, a custom-made nightguard to wear when you sleep might be recommended. This plastic oral appliance, which fits over the teeth, can control or even eliminate clenching and grinding, reducing pressure on the muscles that work the jaw and the jaw joint itself. Some users have reported that their headaches or even migraines are less frequent and/or less intense.

Will a nightguard or other TMD therapy relieve your headaches? It depends on the source of the problem. But living with chronic headaches or facial pain is no fun — so don’t delay scheduling an exam and a consultation.

Inlays and Onlays

There are times when a tooth suffers damage (from decay, for example) that is too extensive to be treated with a simple filling — but not extensive enough to need a full-coverage crown. In these cases, the best option for restoring the tooth may be an inlay or onlay.

Inlay and Onlay Diagram

Both inlays and onlays are considered “indirect” fillings, meaning that they are fabricated outside the mouth (generally at a dental laboratory), and then bonded to the tooth by the dentist. This is in contrast to a “direct” filling, which is applied directly to the cavity by the dentist in one office visit.

An indirect filling is considered an “inlay” when it fits within the little points or “cusps” of a back (premolar or molar) tooth. It is an “onlay” if it covers one or more of these cusps. Either way, the procedure for placing an inlay or onlay is the same.

How It Works

Getting an inlay or onlay is very much like what you would experience having a crown placed, with one important distinction: less of your natural tooth structure will need to be removed by drilling when you receive an inlay or onlay. When you get a crown, the tooth needs to undergo significant reshaping so that it will fit inside its new covering. Since dentistry’s goal is to preserve as much of your natural tooth structure as possible, inlays and onlays may be recommended instead of crowns when a tooth can be restored with this more conservative type of treatment.

The first steps in getting an inlay or onlay are numbing the tooth and surrounding area with a local anesthetic, and then removing the decay. This is done in order to prevent the decay, which is actually a type of infection, from progressing deeper into the tooth.

Once the tooth has been prepared, an impression of it is made (either digitally or with a putty-like material) and sent to the dental laboratory. There, the impression is used to make a model of your tooth for the creation of your inlay/onlay. The final restoration can be made out of gold or a tooth-colored ceramic or resin.

Before you leave the office, a temporary filling will be attached to your tooth to protect it until the permanent restoration is ready. At your second visit, the permanent inlay/onlay will be attached to your tooth with either a resin that hardens when exposed to a special light source, or a type of permanent cement.

Inlays and onlays are strong, long-lasting, and require no greater level of care than any other tooth. Conscientious daily brushing and flossing, and regular professional cleanings at the dental office are all you need to make sure your restoration lasts for years to come.

Oral Cancer Screening

Although oral cancer may not get as much attention as some more widely-known types of cancer, that doesn’t mean it’s any less deadly. In fact, it is estimated that in the United States, oral cancer is responsible for killing one person every hour, every day. While it accounts for a relatively small percentage of all cancers, oral cancer is dangerous because it isn’t usually detected until it has reached an advanced stage. At that point, the odds aren’t great: only about 6 in 10 people will survive after five years of treatment.

If there was a simple test that could give you an early warning about whether you’re likely to have this disease, would you take it? The good news is — there is! Since early detection has been shown to increase the survival rate of oral cancer to 80% or better, this test can truly save lives. And best of all, having an oral cancer screening is part of something you should be doing anyway: getting regular dental checkups.

An oral cancer examination is fast and painless. Its objective is to identify small changes in the lining tissues of the mouth, lips and tongue that may signify the early stages of this type of cancer. The screening is primarily a visual and tactile (touch) examination. If any abnormalities are noted, a small tissue sample can be retrieved for further testing in a laboratory.

Oral Cancer Screening Who’s At Risk for Developing Oral Cancer?

The answer might surprise you. Oral cancer used to be thought of as an older person’s disease, and it still mostly affects those over 40. But today, younger people form the fastest-growing segment among oral cancer patients. This is primarily due to the spread of the sexually-transmitted Human Papilloma Virus (HPV16).

Of course, the other major risk factors still apply: If you’re middle aged or older, a moderate to heavy drinker or a long-time tobacco user, you have a greater chance of developing oral cancer. Chronic exposure to the sun, long known to cause skin cancer, is also associated with cancers of the lips. Genetic factors are thought to have a major impact on who gets the disease as well.

Detecting Oral Cancer

A thorough screening for oral cancer is part of your routine dental checkup — another reason why you should be examined regularly. The screening includes a visual assessment of your lips, tongue, and the inside of your mouth, including a check for red or white patches or unusual sores. You may be palpated (pressed with fingers) to detect the presence of lumps and swellings, and your tongue may be gently pulled aside for an even better view. A special light, dye, or other procedure may also be used to help check any suspect areas. If anything appears to be out of the ordinary, a biopsy can be easily performed.

If you notice abnormal sores or color changes in the tissue of your mouth, lips and tongue, they may be a symptom of oral cancer — most, however, are completely benign. But sores or other unusual changes that haven’t gone away by themselves after 2-3 weeks should be examined. Remember, the only way to accurately diagnose oral cancer is through a laboratory report. Early diagnosis, aided by thorough screenings at your regular dental checkups, is one of the best defenses against oral cancer.

Sealants

Brushing Teeth Without SealantsThe most likely location for a cavity to develop in your child’s mouth is on the chewing surfaces of the back teeth. Run your tongue over this area in your mouth, and you will feel the reason why: These surfaces are not smooth, as other areas of your teeth are. Instead, they are filled with tiny grooves referred to as “pits and fissures,” which trap bacteria and food particles. The bristles on a toothbrush can’t always reach all the way into these dark, moist little crevices. This creates the perfect conditions for tooth decay.

What’s more, a child’s newly erupted permanent teeth are not as resistant to decay as adult teeth are. The hard enamel coating that protects the teeth changes as it ages to become stronger. Fluoride, which is found in toothpaste and some drinking water — and in treatments provided at the dental office — can strengthen enamel, but, again, it’s hard to get fluoride into those pits and fissures on a regular basis. Fortunately, there is a good solution to this problem: dental sealants.

Dental sealants are invisible plastic resin coatings that smooth out the chewing surfaces of the back teeth, making them resistant to decay. A sealed tooth is far less likely to develop a cavity, require more expensive dental treatment later on, or, most importantly, cause your child pain.

How Sealants Are Placed

Step by Step Dental Sealant Process

You can think of a sealant as a mini plastic filling, though please reassure your child that it doesn’t “count” as having a cavity filled. Because tooth enamel does not contain any nerves, placing a sealant is painless and does not routinely require numbing shots. First, the tooth or teeth to be sealed are examined, and if any minimal decay is found, it will be gently removed. The tooth will then be cleaned and dried. Then a solution that will slightly roughen or “etch” the surface is applied, to make the sealing material adhere better. The tooth is then rinsed and dried again. The sealant is then painted on the tooth in liquid form and hardens in about a minute, sometimes with the help of a special curing light. That’s all there is to it!

A note about BPA: A 2012 study that received wide press coverage raised concerns that trace amounts of the chemical bisphenol-A (BPA) found in some (but not all) dental resins might contribute to behavioral problems in children. The study authors noted that while they had found an association, they had not actually proven that BPA in dental sealants causes these problems. In fact, BPA is far more prevalent in food and beverage packaging than in dental restorative materials. The American Academy of Pediatric Dentistry and the American Dental Association have since reaffirmed their support for the use of sealants.

Taking Care of Sealants

Sealed teeth require the same conscientious dental hygiene as unsealed teeth. Your child should continue to brush and floss his or her teeth daily and have regular professional cleanings. Checking for wear and tear on the sealants is important, though they should last for up to 10 years. During this time, your child will benefit from a preventive treatment proven to reduce decay by more than 70 percent.
