The brush should fit properly in the hand. The brush should be soft nylon to prevent scratching the teeth or gums. When brushing, apply medium pressure at a 45-degree angle. Too much pressure can bend bristles and damage your teeth and gums. A toothbrush should be soft enough to massage and stimulate the gums and clean the teeth.
Electric toothbrushes are great, especially for children, disabled adults, and anyone with braces.
A water pick can also help with dental care. Keep in mind water picks do not replace toothbrushes or floss. They are designed to produce a direct pulsating stream of water to wash food particles from between teeth. Select products that display the American Dental Association's Seal of Acceptance. A toothbrush with soft bristles is less likely to injure gum tissue.
