P Permanent Teeth Development
From the age 6 to 12 a child will be losing baby teeth and getting their permanent adult teeth. By the time a child reaches age 21 years all 32 permanent teeth will usually have erupted.
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.
