Baby teeth, also known as primary teeth, typically begin to be replaced by permanent teeth around the age of 6. This process usually continues until about age 12 or 13, when the last of the baby teeth fall out. The exact timing can vary for each child, but the general pattern of losing teeth starts with the front teeth and progresses to the back teeth.
Different people could have a different amount of baby teeth, depending on their age. At around six to ten months, babies grow their first tooth. Then, by the age of three, they have all twenty of the baby teeth. Usually children loose all their baby teeth near the age of twelve or thirteen, sometimes sooner. These twenty baby teeth are gradually replaced with 32 adult teeth.
