3. Strawberries: An enzyme called malic acid is found in both strawberries and many whitening toothpastes. Cut a berry in half, rub on your teeth for approximately one minute, then rinse.
4. Eat cheddar, drink milk. Lactic acid is said to help maintain teeth (meaning the enamel and strength of teeth). Hard cheeses, like cheddar, help to remove other food particles from teeth while fortifying with calcium and vitamin D.
5. Follow your dentist’s recommendations. We preach brushing twice per day for two minutes at a time to our children. Do we follow the same rules? Follow good brushing habits and you’ll combat new stains and rid your pearly whites of old ones.
