Once you become aware of this condition it is important to closely monitor it. Not all teeth have to be treated but should be evaluated by your dentist regularly.

First, try to determine the cause. Your dentist or hygienist can help you. If you are clenching or grinding your teeth, a teeth grinding guard will help prevent further damage.

If you are brushing too hard, make changes in your brushing technique. Using an electric toothbrush is a good way to thoroughly clean your teeth without damaging them. Brushing with mouthwash instead of toothpaste once a day cuts down on abrasion to exposed root surfaces.

To help minimize sensitivity: Avoid abrasive toothpastes and use a soft tooth brush. Use fluoride rinse or gel and sensitivity toothpaste.
