1. Brush twice a day for two minutes. Use a soft-bristled brush and fluoride toothpaste, and angle the bristles toward the gum line.
2. Clean between your teeth every day. Floss, interdental brushes or a water flosser all work; the best one is the one you will use consistently.
3. Drink water, especially after meals. Water rinses away food and acids and keeps your mouth from drying out.
4. Limit sugary and acidic snacks. It is not only how much sugar you eat but how often, so try to keep treats to mealtimes.
5. Keep up with regular checkups. Professional cleanings and exams catch problems early, when they are easiest to treat.
