What is Tooth Sensitivity?

Tooth sensitivity is often caused by the exposure of dentin on root areas due to receded gums or periodontal disease. Normally, the underlying dentin of the tooth (the layer that immediately surrounds the nerve) is covered by enamel in your tooth’s crown, and the gums that surround the tooth. This enamel covering may wear down over time, becoming thinner and providing less protection. Your gums can also recede over time, exposing the underlying root surface dentin. The dentin contains a large numbers of pores or tubes that run from the outside of the tooth to the nerve in the center. When the dentin is exposed, these tubes can be stimulated by changes in temperature or certain foods.

How Can You Tell if You Have Tooth Sensitivity?

If hot, cold, sweet or very acidic foods and drinks, or breathing in cold air, makes your teeth or a tooth sensitive or painful, then you have sensitive teeth. Tooth sensitivity is a very common problem. It is estimated that approximately 25% of adults experience tooth sensitivity. Tooth sensitivity can come and go over time.

What Can You Do if You Have Sensitive Teeth?

First tell your dentist or hygienist. He or she can help you determine the best form of treatment to suit your needs.

Your dentist may prescribe a brush-on fluoride gel or a fluoride rinse. You can also try using toothpaste specially made for sensitive teeth. Always ask your dentist or hygienist about the best way to treat your teeth’s sensitivity.
