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.
After humans grow a bit older after the growth of their deciduous teeth, their teeth will start to fall out to make room for the next set of teeth. This second set of teeth that grows in are a personâs permanent teeth, and if they are taken care of, they will last the rest of their lives. When a person grows in their permanent teeth, they will have 32 teeth instead of only 20. Most of these teeth will grow in the back of the mouth. Types of Teeth That Humans Grow.
