Teeth are named by their set, arch, class, type, and side. Teeth can belong to one of two sets of teeth: primary (baby) teeth or permanent teeth. Often, deciduous may be used in place of primary, and adult may be used for permanent.
After that first tooth breaks through, more and more teeth begin to appear. Most kids have their first set of teeth by the time they are 3 years old. These are called the primary teeth, baby teeth, or milk teeth and there are 20 in all. When a child gets to age 5 or 6, these teeth start falling out, one by one. A primary tooth falls out because it is being pushed out of the way by the permanent tooth that is behind it.
