A majority of the time cavities are due to a diet high in sugary foods and a lack of brushing. Limiting sugar intake and brushing regularly, of course, can help. Every time someone eats, an acid reaction occurs inside the mouth as the bacteria digests the sugars. This reaction lasts approximately 20 minutes. During this time the acid environment can destroy the tooth structure, eventually leading to cavities.
Consistency of a person's saliva also makes a difference, thinner saliva breaks up and washes away food more quickly. When a person eats a diet high in carbohydrates and sugars they tend to have thicker saliva, which in turn means more of the acid-producing bacteria that causes cavities.
Tips for cavity prevention:
- Limiting sugar intake – food as well as sugary beverages
- Insist on regular brushing, flossing and rinsing.
- Drink plenty of water. Not only is it healthy for your body, it is good for rinsing the oral cavity between brushing.
- Avoid sticky foods.
- Choose nutritious snacks.
- Limit frequent snacking
