Most importantly, don’t nurse your children to sleep. Nor should you put them to bed with a bottle of milk, juice or formula. When a child is sleeping, any liquid that remains in the mouth can support the bacteria that produce acid and harm the teeth. A simple pacifier or bottle of water is fine.
Limiting sugar intake and brushing regularly can help prevent cavities. The longer it takes your child to chew their foods the longer the residue stays on their teeth, the greater the chances of getting cavities.
Every time someone eats, an acid reaction occurs inside their mouth as the bacteria digest 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 food and washes it away more quickly. When a person diet is high in carbohydrates and sugars they tend to have thicker saliva, which in turn creates a more acid-producing bacteria environment that causes cavities.
