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 won’t do a good job of cleaning your teeth.
- Make sure to use an ADA-accepted fluoride toothpaste.
