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.
Avoid using hard-bristled toothbrushes and brushing your teeth too hard, which can wear down the tooth's 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.
