Good diet, fluoride toothpaste, Arginine supplements (always consult your physician to make sure it is safe for you).

Good low carb diet. Supplements esp calcium/magnesium, good home care program, Xylitol containing products including gum and mints.

By brushing and flossing regularly and having periodic exams and cleanings you will help strengthen your teeth. The mineral content of your teeth can be affected negatively by acidic beverages(carbonated beverages etc) and positively by calcium rich foods. If you brush and floss you reduce inflammation in your mouth which strengthens the periodic ligament which holds your teeth in the socket.

There are various products of the market that strengthen the teeth the best has fluoride and name brand prevident, flourigaurd. If the teeth have demineralization, then I would recommend a regimen of MI paste these can be purchased at your dentist office.

Have a great day!

Hi
You can either rinse with a fluoride mouthwash or use a toothpaste like Sendodyne Pro- Enamel

Any standard fluoride toothpaste and occasional fluoride treatments at your dentist are the best ways to keep your teeth strong.

Best way to strengthen your teeth is to have a good oral hygiene habits like flossing, brushing and using fluoride rinse or paste after you brush.
