Tooth sensitivity can be reduced by using a desensitizing toothpaste, applying sealants and other desensitizing ionization and filling materials including fluoride by your dentist, and decreasing the intake of acid-containing foods. Tartar control toothpastes will sometimes cause teeth to be sensitive as well as drinking diet soft drinks throughout the day.
Avoid using hard bristled toothbrushes and brushing your teeth too hard, which can wear down the tooth’s root surface and expose sensitive spots. The way to find out if you’re brushing your teeth too hard is to take a good look at your toothbrush. If the bristles are pointing in multiple directions, you’re brushing too hard.
