Why are my teeth sensitive?

Are your teeth sensitive when taking a creamy bite of chocolate ice cream or while drinking a steamy mug of hot chocolate? Here are a few causes of your sensitivity.

Tooth decay (cavities)
Fractured teeth
Worn fillings
Gum disease
Worn tooth enamel
Exposed tooth root

In healthy teeth, a layer of enamel protects the crowns of your teeth—the part above the gum line. Under the gum line a layer called cementum protects the tooth root. Underneath both the enamel and the cementum is dentin. 

Dentin is less dense than enamel and cementum and contains microscopic tubules (small hollow tubes or canals). When dentin loses its protective covering of enamel or cementum these tubules allow heat and cold or acidic or sticky foods to reach the nerves and cells inside the tooth. Dentin may also be exposed when gums recede. The result can be hypersensitivity.

Sensitive teeth can be treated. The type of treatment will depend on what is causing the sensitivity.  Dr. Gardner and his staff are ready and waiting to help you prevent teeth sensitivity so you can indulge in some hot cocoa on a cold day, especially in this holiday season!
