Tooth decay is damage to the enamel of your teeth. It leads to cavities that can affect the deeper layers of the tooth. it occurs when germs (bacteria) in your mouth make acids that eat away the tooth.It can lead to a hole in the tooth, called a cavity. If not treated, tooth decay can cause pain, infection, and tooth loss.
In childhood the tooth decay may causes from over eating of chocolates, soft drinks, or not properly brushing the teeth,etc thus it purely depends on the individual
Things that make you more likely to have tooth decay include:
Children, whose teeth are still growing, are more likely than adults to have tooth decay. This is because the minerals in new teeth are not very strong and are easier for acids to eat away.
Even babies can be at risk for tooth decay. Babies who are put to bed with a bottle can get "bottle mouth tooth decay caused by the sugar in milk, formula, or juice. Babies aren't born with decay-causing bacteria in their mouths. But they can get bacteria from adults who share spoons, forks, or other utensils with them.
