The Prevention of Tooth Decay

Tooth decay may lead to CAVITIES. It is the loss of tooth surface substance caused by germs (bacteria). Bacteria form a sticky layer over the tooth surfaces called PLAQUE. When sugar is ingested, the plaque bacteria convert sugar to acid. The acid may then dissolve the tooth surfaces resulting in cavities.
