A white smile doesn’t happen overnight. Several small positive changes in your routine will contribute to this gradual process. Plaque, the sticky film of bacteria constantly forming at the gum line and on the surfaces of your teeth, can take time to remove. Brush your teeth two to three minutes at a time, and twice daily. Consider using a timer to help ensure you’re spending enough time at the sink, or play a song of the same length encouraging everyone in the house to do the same. Interdental tools such as floss reach many areas of the mouth that your toothbrush can’t and should be used at least once daily before bedtime. Finish your routine by rinsing with mouthwash according to label directions to help keep your teeth and gums healthy.
