Bacteria and sugar: Decay germs eat sugar. They digest it and secrete acid. This acid disolves tooth structure and we call that decay. So, don't eat the sugar and clean really well and the decay rate drops.

Bacteria and sugar: Decay is caused by bacteria which are naturally occurring in your mouth. When the bacteria are fed sugar, either simple like sweets or complex like bread or sugar, they produce acid which eats into the tooth.
