Avoid food and beverages that are high in acid unless you can brush immediately after consuming them. Drink soda, tea and coffee through a straw whenever possible to limit contact. Brush your teeth or rinse your mouth with water immediately after eating citrus fruits, tomatoes and other acidic fruits.

Brush your teeth in a circular motion at a 45 degree angle. Some people brush up and down or side to side, but it is much better to do it in a gentle circular fashion. Hold the brush as if you're holding a pen or pencil, to avoid doing it too hard.
