What can happen if I don't treat my sensitive teeth?

This depends on the cause of the sensitivity. General sensitivity involving several teeth at the same time can be caused by gum recession which exposes the roots of the teeth. The gum recession may be a sign of improper tooth brushing technique or of gum disease. Either of these causes can be harmful to the teeth if not treated or corrected. Sensitivity can also be a sign of cavities (decay). Failure to treat a cavity can lead to an infection in the gums or jaw with pain, swelling, and risk of spreading to other areas of the head and neck in severe cases. It’s best to find out the cause of the sensitivity as early as possible by visiting a dentist. As with many other health problems, early treatment is less costly and less invasive.

Sensitive teeth can be treated. The type of treatment will depend on what is causing the sensitivity. Not treating this will only continue the pain you experience, and may have a lasting impact.

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, and increased chances for cavities at the exposed areas.

Cost, time, and many other things can get in the way of going to the dentist, but sensitive teeth are a sign that you should make an appointment to see your dentist soon. While sensitive teeth may be due to a minor problem, such as a tiny crack in a tooth, they may also signal more serious dental conditions, such as periodontitis, an advanced form of gum disease. Periodontitis can increase the risk of serious overall health problems, such as heart attack, stroke, and, for pregnant women, giving birth to a premature baby. Also, if periodontitis isn't treated, you may lose your teeth. Because of this, it's important to talk to your dentist about your sensitive teeth, no matter how minor the problem may seem.
