Toothbrushes

Key Points

• The consensus recommendation is for people to brush their teeth for two minutes twice a day with a toothbrush that has soft bristles.
• Replace toothbrushes every three to four months or more often if the bristles are visibly matted or frayed.
• Either manual or powered toothbrushes can be used effectively.
• A product earns the ADA Seal of Acceptance by providing scientific evidence that demonstrates safety and efficacy, which the ADA Council on Scientific Affairs carefully evaluates according to objective requirements.
