Learn Everything You Need To Know About Tooth Root Sensitivity
Tooth sensitivity to cold and/or sweets may be a sign of a cavity, but it may also be caused by root sensitivity. Teeth are made up of a very hard substance called enamel, which protects the nerve inside the tooth from the stimuli your teeth experience, such as hot, cold, sweets, and chewing.
The surface of the root of the tooth is covered by a material called cementum that is not as strong as enamel, but is protected by the overlying gum tissue. Tooth sensitivity basically occurs when something happens to cause the gum tissue to recede, leaving the sensitive cementum exposed.
Causes
One of the most common factors of gum recession is due to the toothbrush. The process is caused by brushing too hard or by using a hard bristled toothbrush, thereby causing the gums to recede. The use of a soft toothbrush with proper technique can help prevent this recession.
Chemical erosion is another cause of root sensitivity. This can occur in people who drink an excessive amount of carbonated beverages or suck on highly acidic foods, such as lemons or limes. The acids in these products can actually eat away the protective enamel coating of the teeth right along the gum line, leading to sensitivity.
This same type of tooth sensitivity may also occur after any dental treatment that affects the position of the gum tissue on the tooth. Some examples would be gum surgeries that expose more tooth structure or the extraction of teeth, which may cause shrinkage of the gum tissue in the area adjacent to other teeth.
Treatment of Root Sensitivity
The most critical aspect in treating root sensitivity is accurately diagnosing and treating the cause with your dentist. If the cause is not known and corrected, the problem will continue to recur in spite of treatment. Treatment is aimed at coating or sealing the surface of the exposed root to prevent the stimulus (cold, sweets) from transmitting to the nerve of the tooth, causing sensitivity.
There are toothpastes available at most stores that are specifically designed for sensitive teeth. These products decrease the sensitivity over time, although you may find if you stop using them, the sensitivity returns. This may be because the underlying cause has not been treated.
Another option is to have a highly concentrated fluoride gel applied to the sensitive areas at your dentist's office. Your dentist can also seal the area with a thin coating of resin. This is not like a filling, but more like a thin coat of a clear liquid that helps to seal your tooth when it is placed and cured.
Placing restorations (fillings) in the exposed areas will also seal them, but unless the cause of the tooth sensitivity is identified and corrected, the gum may continue to recede past where the filling was placed, causing a new area of root to be exposed below the level of the filling. If the recession is more extreme, a gum graft may be placed, where gum tissue is taken from another part of your mouth and grafted over the exposed area.

Diabetes and Dental Care: Learn Everything You Need To Know
Diabetes, affecting millions of Americans, increases the risk for multiple dental problems. If you are diabetic, be sure your health condition is reflected in your dental records. Your dentist will want to carefully monitor your oral health needs.
Diabetics must pay special attention to the following conditions related to oral health:
Tooth Decay
High glucose levels in saliva help bacteria to thrive, repeatedly attacking teeth with cavity-causing acids. Brushing at least twice a day with fluoride toothpaste and flossing daily is vital.
Gum Disease
Diabetes reduces the body's resistance to infection and gum tissues are frequently affected. Diabetics may experience more frequent and severe cases of periodontal disease. See your dentist if you notice any of these symptoms: your gums are tender, red, swollen, or bleed easily; your gums have pulled away from the teeth; or you notice any pus between the teeth and gums when the gums are pressed. Other indicators are chronic bad breath or a bad taste in your mouth; any changes in your bite or fit of partial dentures; or permanent teeth that become loose. Since diabetes can impair the healing process, abscesses can develop, so it is important to schedule regular periodontal exams.
Oral Fungal Infections
People with high glucose levels who smoke or frequently take antibiotics are more prone to develop oral candidiasis, or thrush. This is a condition where white or red patches in the mouth become ulcerated and attack the tongue with a painful, burning sensation. Swallowing can be difficult and your ability to taste can be impaired. Antifungal medications can be prescribed by your dentist.
Taste Impairment
A diminished sense of taste can influence food choices. Diabetics have reported that their perception of sweetness is lessened. As a result, selecting sweet-tasting, refined carbohydrate foods puts diabetics at greater risk for developing both general health and dental problems.
Dry Mouth: Diabetic patients often complain about dry mouth due to salivary gland dysfunction related to the disease. Constant dryness irritates the soft tissues causing inflammation and pain. It can also increase the likelihood of tooth decay and gum disease.
Saliva substitutes available in pharmacies can relieve discomfort. Sugarless gum, sugarless mints, and drinking plenty of water also are useful in combating dry mouth. Additionally, restrict consumption of caffeine and alcohol.
Mouth Lesions
Pimple-like sores, generally painless, dot the mouth tissues. In a more severe condition, the tissue becomes painfully ulcerated. No permanent cure is available, but your dentist can prescribe medication to relieve the condition.
Since diabetics are more prone to conditions that jeopardize oral health, regular dental check-ups and periodontal screenings are essential. More frequent evaluations may be needed to ensure optimum oral health.
Bad breath, or halitosis, is a signal that something is not right inside your mouth. It may be as simple as the need to pay more attention to your daily oral hygiene, or it may indicate tooth decay, gum disease, or another medical problem. Whichever it is, bad breath is a red flag: take another look at your mouth!
Bad breath is a social problem; if you have bad breath, you may notice that people actually back away as you talk to them. Mouth odors are embarrassing, and they tell other people that you aren't taking care of yourself. Sometimes people are not aware that their breath smells bad; be alert to how other people react when they're close to you, and be grateful if a friend or family member lets you know about the problem.
Commercial products claim they will make your breath fresher, but the only way to make sure your breath permanently fresh is to practice good oral hygiene. In fact, too many breath mints and hard candies with sugar will lead to tooth decay. If you are constantly using breath mints, breath sprays, or mouth rinses in an effort to cover up your bad breath, realize that you may have a dental or medical problem that needs addressing.
There are a number of reasons you may experience a bad taste in your mouth, and even be able to smell your own breath. Food may be lodged between your teeth if you are not brushing at least twice daily and flossing regularly. Food particles can be very tiny and can wedge themselves between teeth and below the gum line; brushing after meals is important and flossing is imperative to get at the particles that the brush can't reach. Brush your tongue or use a tongue scraper. As odd as it will feel at first, bacteria collects on the tongue and can contribute to bad breath. If you wear removable dentures, take them out at night and clean them thoroughly before you wear them again.
If you neglect your daily hygiene over time, bad breath can become a symptom of more serious dental problems. Teeth that are not cleaned properly become a place for bacteria to reside as food particles stay in your mouth and decay. Bacteria attack your teeth and gums and cause cavities and gum disease. If this is happening, gum disease will cause an unpleasant odor.
Perhaps you believe that you are brushing and flossing on a regular basis, but are still experiencing bad breath. If you have teeth that are crooked or crowded, it may be hard for you to clean between them. If you wear dentures that are not fit properly, they may be trapping food or irritating your mouth. Or perhaps your bad breath is caused by another medical problem: drainage from your sinuses, gastrointestinal problems, kidney or liver problems, or other medical conditions.
Here's what you can do to "investigate" on your own. Write down what you're eating and notice whether your breath smells bad because of certain foods. Garlic and onions actually cause odor, but the odor is coming from your lungs as you breathe, not from your mouth itself. The odor from these foods is temporary, and will be gone once the food is out of your bloodstream.
Are you dieting? Hunger can contribute to bad breath, because of the chemical changes as your body turns fat and protein into the energy it needs. Taking prescription or over-the-counter medications? Add these to the record of what you're eating to see whether there's a relationship between your medications and your bad breath. And don't forget to tell your dentist if there's been a change in your overall health since your last visit.
Suffering from dry mouth? Saliva provides constant rinsing in our mouths and washes away food particles. Your dentist may recommend more liquids, sugarless candy to stimulate natural saliva, and perhaps some of the commercial products that are available to combat dry mouth.
If bad breath continues after you have done your best job of regular brushing and flossing, start with your dentist. He or she can tell you whether the odor is caused by an oral problem; if it is not, then your dentist will suggest you see your doctor for a physical check-up.
Regular dental check-ups will help keep your mouth healthy and working well. Your dentist can spot dental problems before they cause trouble, including problems that cause bad breath.
