Brushing your teeth is an important part of your dental care routine. For a healthy mouth and smile the ADA recommends you: Brush your teeth twice a day with a soft-bristled brush. The size and shape of your brush should fit your mouth allowing you to reach all areas easily. Replace your toothbrush every three or four months, or sooner if the bristles are frayed. A worn toothbrush wonât do a good job of cleaning your teeth.
When you brush your teeth: 1  Brush your teeth 2 times a day, in the morning and at night. 2  Use a toothbrush with soft, rounded-end bristles and a head that is small enough to reach all parts of your teeth and mouth. Do not scrub. 2  Vigorous brushing can make the gums pull away from the teeth and can scratch your tooth enamel. 3  Brush all surfaces of the teeth, tongue-side and cheek-side. 4  Pay special attention to the front teeth and all surfaces of the back teeth.
