What causes sensitive teeth?
Cavities and fractured teeth can cause sensitive teeth. If these problems have already been ruled out by Dr. Snell, then the worn tooth enamel or an exposed tooth root may be the cause.
A layer of enamel, the strongest substance in the body, protects the crowns of the healthy teeth. A layer called cementum protects the tooth root under the gum line. Underneath the enamel and the cementum is dentin, a part of the tooth that is less dense than enamel or cementum.
The dentin contains microscopic tubules (small hollow tubes or canals). When dentin loses it's protective covering, the tubules allow heat and cold or acidic or sticky foods to stimulate the nerves and cells inside the tooth. This causes hypersensitivity and occasional discomfort. Fortunately, the irritation does not cause permanent damage to the pulp.

How to prevent sensitive teeth.
Proper oral hygiene is key to preventing gums from receding and causing sensitive-tooth pain. To schedule your teeth cleaning and exam, please call our Gilbert, Arizona office today at 480-457-8600. If you brush your teeth incorrectly or even over-brush, gum problems can result. Come in and ask Dr. Snell and our professional staff any questions you might have about your daily oral hygiene routine.
Treatment
Sensitive teeth can be treated. Dr. Snell may suggest that you try a desensitizing toothpaste, which contains compounds that help block transmission of sensation from the tooth surface to the nerve. Dr. Snell recommends Sensodyne Toothpaste. Desensitizing toothpaste usually requires several applications before the sensitivity is reduced.
If Sensodyne doesn't ease your pain, Dr. Snell may suggest in-office techniques. A fluoride gel, which strengthens tooth enamel may be applied to the sensitive areas of the teeth.
In cases where hypersensitivity is severe, persistent and cannot be treated by others means, Dr. Snell may recommend endodontic therapy (root canal).
Please call our Gilebrt, Arizona Office located at 3592 S. Atherton Blvd #112, Gilbert, Arizona 85297 to schedule your oral health exam today. Or call us at 480-457-8600!
