UnderstandingDryMouth

The medical term for dry mouth is xerostomia (“xero” – dry; “stomia” – mouth), something that many of us have experienced at some point in life. However, for some people it can be a chronic condition that is ideal for promoting tooth decay. It can also be a warning sign of a more serious health condition.

Dry mouth occurs when there is an insufficient flow of saliva, the fluid secreted by the salivary glands. Your major salivary glands are located in two places: inside the checks by the back top molars and in the floor of the mouth, with about six hundred tiny glands scattered throughout your mouth. And many people are surprised to learn that when they are functioning normally, saliva glands secret between two and four pints of saliva per day! While this may sound like a lot (and it is), saliva is key for buffering or neutralizing acids in the mouth. Without this powerful protection, tooth decay can increase quickly. This is especially true for older individuals who have exposed tooth root surfaces.

It is also important to note that there are times when mouth dryness is perfectly normal. For example, when you wake, you will probably have a slightly dry mouth because saliva flow slows at night. Another example is if you are dehydrated when it is simply a warning sign that you need to drink more fluids (especially water). Other causes for temporary dry mouth include stress as well as what you consume: coffee, alcohol, onions, and certain spices.

You can also have a dry mouth due to a side effect from an over-the-counter (OTC) or prescription medication. If it turns out that this is the cause in your case, you need to talk to the prescribing physician to see if there is something else you can take to avoid this side effect. If there are no substitutes, one tip you can try is to take several sips of water before taking the medication followed by a full glass of water, or chew gum containing xylitol, which moistens your mouth and decreases the risk of tooth decay.

Another cause of dry mouth is radiation treatment for cancer in the head and neck region. Yes, these treatments are crucial for fighting cancer; however, they can inflame, damage or destroy salivary glands. You can also have dry mouth from certain systemic (general body) or autoimmune (“auto” – self; “immune” – resistance system) diseases, diabetes, Parkinson's disease, cystic fibrosis and AIDS (Acquired Immune Deficiency Syndrome).

NotJustFillingintheGapsLostTeethHaveUnexpectedConsequences

Why is it important to replace missing teeth with restorations such as dental implants? You might be surprised to find that the damage caused by missing teeth is much greater than the simple gaps left in your smile.

As the years go by, teeth lost early in adulthood cause structural changes in a person's face. By age 45 changes in facial structure are already visible in the form of sunken cheeks. By 60, cheeks and lips lose their support, resulting in an aging look. This process continues and if the teeth are not replaced, much of the structural support of the person's face is lost.

These changes are caused by loss of bone. Although it may seem static, bone is actually living tissue that needs constant stimulation to maintain its form and density. With normal stimulation it is in a constant state of resorption (breaking down) and deposition (building up). Teeth provide the needed stimulation for the bone that surrounds them (called alveolar bone) as they meet each other during biting, chewing, and speech. When the stimulation continues, the bone continues to rebuild itself. Without this stimulation, the bone resorbs, does not build up again, and loses substance.

Without stimulation, alveolar bone loses width, height, and volume. Since your teeth and their surrounding bone support your chin, cheeks, and lips, this has a powerful effect on your appearance. It may also affect your ability to chew and to speak.

As alveolar bone diminishes, the next layer of bone also begins to resorb. This is the bone of the jaw itself. The lower part of the face begins to collapse, and the cheeks become hollow. This effect is especially noticeable for people with no teeth (edentulous).

Usually the first tooth to be lost, due to infection and decay, is a molar (back tooth). In the past, a missing single back tooth was frequently replaced by a fixed partial denture (FPD). A crown is provided for each of the two teeth on the sides of the gap, called abutment teeth, to support a false tooth in the middle. However, if they are not well cared for, the abutment teeth may be the next to succumb to decay.

Today the treatment of choice is an implant. A dental implant is a tooth-root replacement made of titanium, which fuses with the bone — making it very stable. Above the gums it is covered by a crown that looks like a natural tooth. The benefit of the implant is that it continues to provide stimulation to the alveolar bone, preventing bone loss.

Implants are also a good choice in the case of multiple missing teeth. They can be used to support bridges or false teeth (dentures). The results are an improved, younger appearance and better functionality.

BadBreathTryaTongueScraper

Bad breath can have a serious impact on a person's social and business life. Americans are well aware of this fact, and spend nearly $3 billion each year on gums, mints, and mouth rinses in order to make their breath “minty fresh.”

Bad breath or halitosis (from the Latin halitus, meaning exhalation, and the Greek osis, meaning a condition or disease-causing process) can originate from a number of causes; but oral bacteria are the most common source. About 600 types of bacteria grow in the average mouth. If bacteria act on materials that have been trapped in your mouth, many of them produce unpleasant odors.

Most often, bad breath starts on the back of the tongue, the largest place in the mouth for a build-up of bacteria. In this area bacteria can flourish on remnants of food, dead skin cells, and post-nasal drip. As they grow and multiply these bacteria produce chemical products called volatile sulfur compounds or VSCs. These compounds emit smells of decay reminiscent of rotten eggs.

In addition to bacteria on the tongue, halitosis may come from periodontal (gum) disease, tooth decay, or other dental problems. If you have halitosis, it is thus important to have a dental examination and assessment, and to treat any such problems that are found. Treating bacteria on the tongue without treating underlying periodontal disease will only temporarily cure bad breath.

The next step is to take control of tongue bacteria by brushing or scraping your tongue, with possible addition of antiseptic mouth rinses. People who have bad breath have more coating on their tongues than those who don't, and regularly cleaning the surface of the tongue has been demonstrated to reduce bad breath.

Implements have been designed specifically for the purpose of scraping or brushing the surface of the tongue. Using a toothbrush is not as effective because it is designed to clean the hard tooth surface, rather than the spongy surface of the tongue. To keep your breath fresh, you must regularly remove the coating from your tongue. This means acquiring a tongue scraper or brush and using it every day.

TeethWhiteningWhatYouNeedToKnow

Some of the most popular smile enhancers on the market today are both over-the-counter (OTC) and professional teeth whitening products. And while studies indicate that bleaching can successfully achieve noticeable increases in whitening of stained teeth, there are some facts you need to know about these products and the results that they can deliver.

  • Nearly all bleaching products contain the same basic ingredient, carbamide peroxide or its breakdown product, hydrogen peroxide. However, the products our office uses to professionally whiten your teeth are much stronger without compromising the health and safety of your teeth, gums, and mouth.
  • OTC bleaches typically contain no more that 10% carbamide peroxide while professional bleaches can contain between 15% and 35%. And to make professional bleaching even more effective, we may use them in combination with specialized lights or lasers.
  • Bleaching is NOT a permanent solution and thus results will diminish over time. The “fade rate” begins to occur 6 to 12 months after treatment.
  • While you can't avoid the fading process, you can extend your bleaching results by avoiding foods and drinks that stain your teeth, such as red wine, red (tomato-based) sauces, coffee, tea, sodas/colas, and blueberries to name a few.
  • Another method for extending your results is to use a straw when drinking beverages that can stain your teeth so that the liquid does not come in contact with your teeth.
  • If you have visible crowns and/or veneers mixed with your natural front teeth, it may be quite difficult for you to bleach your natural teeth so that they perfectly match your veneers or crowns. Remember, tooth whitening is not effective on crowns, veneers, bridgework, or any type of artificial tooth.
  • One of the most common side effects of whitening teeth is tooth sensitivity and irritation of the gum tissues. They both are usually temporary and often occur when you start bleaching; however, they generally subside after a few days.

Overall, bleaching your teeth is an effective way to brighten your smile with minimal side effects. If it is something you are interested in pursuing, talk it over with us first — even if you plan to use OTC products — so that you have a clear understanding about your specific options and projected outcomes.

FrequentlyAskedQuestionsaboutBumpsintheMouth

When it comes to your oral healthcare, we strive to provide state-of-the-art care along with education to both our patients and community. One way we do this is by taking a moment to answer some of the questions we are most often asked about a certain topic. And one topic that almost always ignites questions is the subject of lumps and bumps in the mouth.

Help! I just found a small lump in my mouth — what should I do?
Not to alarm you, but your first priority is to contact us as soon as possible to schedule an appointment so that we can review it. Most often, we will know what it is by taking a history, knowing how long it's been there and what it looks like. Depending on what we find, we may want to take a biopsy so that we can determine exactly what it is and how we need to treat it.

What is involved in having a biopsy performed?
A biopsy is a normal and routine procedure that is used to definitively diagnose and confirm exactly what the abnormal lump, bump or other tissue is. It is typically performed with local anesthesia so that a small tissue sample can be removed without any pain for examination under a microscope. Depending on the size of the wound, it may require two to three sutures (stitches), leaving a flat and flush surface that heals in a few days to a week. The procedure usually lasts between 10 and 15 minutes with the lab results processed within a few days.

Does this mean I have cancer?
No, the chances are slim that you actually have cancer. However any change or sore in the mouth that does not heal in a week or two should be evaluated by a dentist and if necessary biopsied. If it is pre-cancerous and removed, it could save your life. The most important fact you need to remember is that no one can tell for sure what the abnormal tissue growth is until an expert in oral pathology (“patho” – disease; “ology” – study of) examines it under a microscope. While it is human nature to be concerned, until you have the facts, you are suffering needlessly.

To learn more about this topic, continue reading the Dear Doctor magazine article “Common Lumps and Bumps In The Mouth.” Or you can contact us today to schedule an appointment to discuss your specific questions so that we can put your mind at ease.
