How do sweet things cause tooth decay?

Bacteria: Tooth decay is caused by bacteria living in your mouth. The bacteria use carbohydrates (sugars) to produce acids which breakdown the surface of the tooth. This breakdown is tooth decay. Keep in mind, it is not how much sweet things you eat but how often you eat them that affect tooth decay.

Bacteria: Not only sweets but everything we eat causes cavities. What causes cavities are more the frequency of eating and frequency you clean your teeth. Cavities are formed as bacteria in our mouth feed on food left behind and production of acids that softens the tooth structure.

Sweet things: Are generally sugar rich -- candies, toffees, cakes, sodas, energy drinks, sweet tea ... The more exposure the sugars have with the teeth, the more likely you are to develop cavities. Everything in moderation and maintain good oral hygiene (not the national average of a 28 second toothbriushing) brush at least 2 minutes am and pm, waterpik or floss and see your dds regularly.
