Plenty. If you have a history of tooth decay or are at high risk for it, the key is to decrease the bacteria present in your mouth and eliminate acidity. And you can do exactly that if you do the following:
1. Drink water throughout the day, especially if you’re active. Prolonged
physical activity can dry your mouth.
2. Limit (or eliminate) alcohol and caffeine. Either will dry out your mouth.
3. Ditch cigarettes once and for all. Both smoking and chewing tobacco cause dry mouth.
4. Avoid sugary snacks and drinks between meals.
5. Use prescription-strength fluoridated toothpaste.
6. Use xylitol-sweetened toothpaste, gum, and mouthwash. Xylitol decreases the stickiness of plaque on teeth, making it easier to brush or rinse away.
7. Choose a toothpaste containing calcium and phosphate, which replenish
the minerals in your teeth and strengthen them.
8. Use a pH-balanced mouthwash and toothpaste.
9. Eat spinach, soy, seafood, nuts, and other foods rich in arginine
(a component of protein), which deposit a mineral containing calcium and phosphate on the teeth, desensitizing them and making them less
vulnerable to decay.
10. Take probiotic supplements, or eat foods such as yogurt containing
probiotics—healthy bacteria that aid digestion and also reduce plaque.
11. Eat cheese, which coats the teeth with a layer of fat that minimizes acid
12. Use a toothpaste with low abrasiveness as explained on page 17.
13. Use an electric brush and an irrigator, such as Waterpik, to remove as
many food particles as possible.
