A Dr. Benjamin S Fiss DDS , Dentist, answered. Brush your teeth in small circles, two teeth at a time, at a 45 degree angle to the tooth enamel. Brush your teeth at least two times per day slowly over 1-2 minutes. Ideally, you should brush your teeth after every meal and especially after eating sugary foods.
The American Dental Association recommends brushing 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. Use a toothpaste that contains fluoride, which helps protect your teeth from decay.
