Brushing your teeth is an important part of your dental care routine. For a healthy teeth and gum ADA recommends:

• Brush your teeth twice a day with a soft-bristled brush.
• Replace your toothbrush every three or four months, or sooner if the bristles are frayed.
• Recommended to use an ADA-accepted flouride toothpaste.
• Place your toothbrush at a 45-degree angle to the gums. 
• Gently move the brush from the gumline downward
• Brush on all the three surfaces of teeth
• To clean the inside surfaces of front teeth, tilt the brush vertically and brush with up-and-down strokes.
