Shown here is the anatomy of the common human molar. Different diseases or disorders affect each part of the tooth. Treatment of each disease is specific to the etiology and extent of the tooth/tissue damage. Tooth decay or "dental caries" is thought to be caused by a bacteria in the plaque called strep mutans. Every time teeth are exposed to foods, especially sweet, sticky foods- plaque on the teeth digests it and produces acid. With the acid produced, Strep mutans may decalcify the enamel surface and if allowed to continue will penetrate to the dentin. Once inside the dentin decay will spread more quickly throughout the tooth, usually towards the pulp and along the junction between the enamel and dentin. As the cavity reaches the pulp or approximation to it, the nerve in the pulpal cavity may become irritated or die. At this point the tooth may become cold, hot or pressure sensitive. The pulp is the blood and nerve supply to the tooth. A dentist can usually fill a cavity, if caught in time, but if the decay is allowed to reach the pulp and the nerve dies, a root canal may be needed. Some beginning "cavities" may be stopped or reversed if they are only in the enamel by good oral hygiene practices. Some suggestions to help reverse or prevent cavities would be to floss everyday, use a fluoridated mouth rinse , brush three times a day and change your diet to eliminate or cut down on sweet foods. Always consult a physician before making changes in you diet.

Gum disease or periodontitis is also caused by bacteria in the plaque. Periodontitis is a swelling of the gum tissues which leads to jawbone destruction and pocket formation between the gum, bone and tooth. It is thought to be caused from a gram negative strep bacteria. People may have the tendency to develop gum disease if found in other members of their families. Again, the most important tool to prevent this is home care and regular dental visits! Some signs of gum disease may be bleeding when brushing or flossing, loose teeth and bad odors-tastes from your mouth. If you have any of these signs or symptoms, it is a good idea to visit your dentist.

Another common problem is "cracked tooth syndrome". Have you ever gone to the dentist for a sensitive tooth and have them tell you there is a hairline fracture in your tooth ? Because of trauma and normal use, teeth will develop cracks and become sensitive to the bite, cold or hot foods. Sadly, the options to cure this aliment are limited. In the past we could only observe the tooth or crown it. Today, in addition to the aforementioned treatments, new adhesives in dentistry give the added strength when filling teeth to help support them. In addition, new tooth pastes are now available to help desensitize the teeth.
