What is dentin hypersensitivity?
Dentin hypersensitivity, more commonly referred to as sensitive teeth, can be defined as short, sharp pains that come from exposed dentin (the layer of tissue found beneath the hard enamel that contains the inner pulp). Individuals with sensitive teeth may find that the pain can be triggered by hot, cold, sour, or sweet beverages or foods, forceful brushing or flossing, or even cold air.

How can I avoid dentin hypersensitivity?
I have dentin hypersensitivity. What can I do to prevent pain?
Using a soft-bristled toothbrush and brushing in a circular motion will minimize enamel abrasion and thus reduce sensitivity. Using toothpaste containing a desensitizing agent that protects exposed dentin by blocking the pores connected to nerves can alleviate pain. In-office treatments, such as topical agents or sealants, can be applied by a dentist to help reduce sensitivity. Of course, limiting your intake of acidic foods and beverages is always recommended.
