Children ordinarily get twenty baby teeth. Here's a chart of when they usually come in and when they usually fall out.

|
When they appear |
When they fall out |
Lower front four baby teeth |
age 6-9 months |
ages 6-7 years |
Upper front four baby teeth |
age 7-10 months |
ages 7-8 years |
Canine baby teeth, upper and lower |
about age 1 year |
ages 10-12 years |
First primary molars, right behind the canines |
about age 1 1/2 years |
ages 10-12 years |
Second primary molars |
about age 2 years |
ages 10-12 years |
The first permanent molars are often the first permanent teeth to erupt. But there are no teeth that have to fall out for these to come in. They come in around age 6 or 7 years, behind the second primary molars.

When you have your regular dental visits, your dentist should check that the baby teeth are coming in on schedule and falling out on schedule. If you can see the permanent tooth already appearing in the mouth but the baby tooth hasn't fallen out yet, it's generally recommended to have that baby tooth extracted.
