One of the best ways to prevent sensitive teeth is to maintain good oral hygiene. Regular brushing, flossing and dental examinations can help prevent a number of factors that cause sensitive teeth, including tooth decay and periodontal (gum) disease.

However, patients are urged to consult their dentist if they are unsure of proper oral hygiene techniques. Well-intentioned but incorrect techniques (e.g., brushing too hard, snapping floss against the teeth and gums) can injure the gums, exposing the roots of the teeth and increasing sensitivity. Brushing too hard is often an ingrained habit. A person is brushing too hard if the bristles on the brush are pointing in several different directions.

Patients are urged to brush gently with a soft-bristled toothbrush, or to use a powered toothbrush that has a pressure sensor. This type of brush stops working when the patient applies too much pressure during brushing.

Patients may be advised to avoid using teeth whitening solutions, including whitening or tartar control toothpastes, which can increase tooth sensitivity. Regular use of desensitizing toothpaste may be recommended to maintain the teeth’s resistance to stimuli.
