Tooth sensitivity — also known as dentin hypersensitivity — affects the tooth or exposed root surfaces. This occurs when the enamel that protects your teeth gets thinner, or when gum recession occurs, exposing the underlying surface, the dentin, thus, reducing the protection that the enamel and gums provide to the tooth and its root. Tooth sensitivity affects up to 57% of the population.

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 may have sensitive teeth. Tooth sensitivity can come and go over time.

There are many causes of tooth sensitivity, including:

Proper oral hygiene is the key to preventing gums from receding and causing sensitive-tooth pain. If you brush your teeth incorrectly, or over-brush, your gums may become sensitive. Ask your dentist if you have any questions about your daily oral hygiene routine.

Brushing properly twice daily for 2 minutes with toothpaste that does not have high levels of abrasives, and flossing once a day, can help reduce the chance of tooth sensitivity. A diet low in acidic foods and drinks also helps prevent tooth sensitivity.

In addition to recommending toothpaste without high levels of abrasives, your dentist may prescribe an at-home, brush-on fluoride gel or a fluoride rinse, or high fluoride level toothpaste specially formulated to make your teeth less sensitive and provide extra protection against decay. Other treatments — such as fluoride varnishes — can be painted onto the teeth to provide added protection.

There are several conditions which can cause pain, but which are not tooth sensitivity:
