Generally, a toothbrush should have a long, wide handle (for a firm grasp) and soft nylon bristles with rounded ends so you won't hurt your gums. A toothbrush head should be small (1" by 1/2") for easy access to all areas of the mouth, teeth and gums. Be sure to brush on both sides of the teeth and the tongue. Change toothbrushes every three to four months before their bristles become frayed. Toss the toothbrush after an illness to avoid harmful bacteria harbored in the bristles.
Electric toothbrushes are a great option for those who have limited dexterity, such as older people or arthritis sufferers, and are effective for people with braces since the rotating heads can clean hard-to-reach areas.
