Jawaban:

Brush your teeth twice a day... When you brush, don't rush. Take about two minutes to do a through job. Don't brush right after eating, especially if you had something acidic such as grapefruit or soda. Don't forget to clean your tongue, which harbors bacteria, with a toothbrush or tongue scraper.

- Practice good technique... Hold your toothbrush at a slight angle — aiming the bristles toward the area where your tooth meets your gum. Gently brush with circular short back-and-forth motions. Brushing too hard or with hard bristles can hurt your gums.

- Know when to replace your toothbrush... Invest in a new toothbrush or a replacement head for your electric or battery-operated toothbrush every three months — or sooner if the bristles flay or become irregular.
