Tooth decay is a problem for many children. Tooth decay is caused when bacteria (germs) in your mouth combine with sugar that you eat or drink to make acids that dissolve the outer layers of your teeth. If too much dissolves, your tooth breaks down, and you end up with a "cavity" or hole in your tooth.

For most kids, teeth can be protected from decay by daily brushing with fluoride toothpaste, limiting snacks and drinks with lots of sugar, and having regular dental check-ups.
