Are Your Teeth Temperamental? Dealing With Sensitive Smiles

Are you overly sensitive? Relax, it has nothing to do with crying during life insurance commercials. Millions of adults struggle with hypersensitive teeth, which means they are sensitive to hot and cold temperatures, very sugary or acidic foods and drinks and vigorous tooth brushing. This kind of sensitivity is often called "dentin hypersensitivity."

Dentin is the tissue that makes up the core of each tooth. Above the gum line, dentin is protected with a coating of enamel. Unfortunately, as enamel is worn away or decayed, dentin becomes exposed and receptive to sensations that cause painful nerve responses. This can also occur as the result of receding gums, a common symptom of gum disease.

So, what causes sensitive teeth? A number of things may be to blame. Over-zealous brushing with a firm bristled tooth brush or abrasive toothpaste can lead to dentin hypersensitivity, as can gum disease, which is the result of poor brushing and flossing habits. Your diet may also play a role, as frequent consumption of acidic foods and drinks can chemically dissolve tooth enamel. Finally, abnormal wear on tooth surfaces from chronic clenching or grinding of teeth, nail biting and chewing on hard objects can lead to sensitive teeth. To avoid the problem, brush and floss daily to maintain healthy gums and protect dentin from exposure. Avoid vigorous tooth brushing with a hard-bristled toothbrush.

If you're already suffering from overly sensitive teeth, your best bet is to contact your dentist for guidance on dental hygiene. In the mean time, there are products that can help. Desensitizing toothpaste used in conjunction with a soft-bristled toothbrush can help. Toothpaste designed for those with sensitive teeth can reduce the pain associated with the condition after only a few days of use.

Xylitol: Chew Your Way To Healthier Teeth and Gums?

Are you crazy about gum, but not so much about its affect on your teeth? (Good for you!) Researchers presenting at the American Academy of Pediatric Dentistry Annual Session in Cincinnati found a natural sweetener may not only improve the taste of gum, juice and candy, it may also reduce tooth decay and increase dental hygiene.

Their study observed children of Belize over the course of several years, some of whom chewed gum with sugar, others with artificial sweeteners. Results showed that those who chewed gum artificially sweetened with Xylitol, a natural sweetener found in trees and fruit that does not cause cavities, suffered from less tooth decay over the duration of the study.

Another study done in Finland found fewer mothers transmitted cavity-causing bacteria to their children when they chewed gum with xylitol. The bacteria transmission occurs when mother and children share eating utensils.

Xylitol is widely available in most supermarkets, but know that it's difficult to achieve the correct dosing. To see results, you'd have to chew gum with a high dose of Xylitol frequently and for prolonged durations. Products containing this natural sweetener may also cost more than those artificially sweetened with other additives.

So, the next time you're dying for a piece of chewy goodness, consider grabbing a brand containing Xylitol. While it can be difficult to obtain optimum results through its use, it is certainly better for your dental health to chew than gum containing sugar.
