This decay is a damage that happens to your teeth. How does it start?
Food containing carbohydrates is left on the teeth. Bacteria that lives in the mouth digest these leftovers and turn them into acid. The bacteria, acid, leftover food and saliva then combine to form plaque which clings to the teeth. The acid in plaque then dissolves the enamel which is the outer coating of the teeth, gradually creating holes in the teeth called cavities. Not cleaning your teeth or a poor dental hygiene can also lead to cavities. If you have gotten to the point where there are cavities on your teeth there will be a few signs.
