When the hard enamel is worn down or gums have receded, causing the tiny dentinal tubule to be exposed, pain can be caused by touching your teeth with hot or cold foods and beverages, or exposing them to cold air. Exposed areas of the tooth can cause pain and even affect or change your eating, drinking, and breathing habits. Taking a spoonful of ice cream, for example, can be a painful experience for people who have sensitive teeth. Tooth sensitivity is one of the most common complaints among dental patients. Some toothpastes contain abrasive ingredients that may be too harsh for people who have sensitive teeth. Tooth sensitivity can be reduced by using a desensitizing toothpaste; having your dentist apply sealants and other desensitizing and filling materials, including fluoride; and decreasing the intake of acid-containing foods.

If a tooth is highly sensitive for more than three or four days and reacts to hot and cold temperatures, it’s best to get a diagnostic evaluation from your dentist to determine the extent of the problem.
