Tooth decay is the destruction of your tooth enamel, the hard, outer layer of your teeth. It can be a problem for children, teens and adults. Plaque, a sticky film of bacteria, constantly forms on your teeth.
The most expected sugars to give tooth decay are sucrose, glucose, fructose, and maltose. Bacteria use the energy in the sugar and then make acids which attack teeth and tooth enamel. This then causes tooth decay, which is also known as dental caries.
