Babies are born without teeth. They get their first set of teeth when they are one or two years old. These are called baby teeth , and we have 20 of them. Then, between the ages of six and twelve, we lose our baby teeth and get 32 adult teeth. We need our teeth to break down food so that we can digest it. We need to brush our teeth at least twice a day to make sure they stay healthy.
digest: v. to break down food in the stomach and absorb it in the body
