Why Are My Child’s Adult Teeth Erupting Behind the Baby Teeth?

It may surprise you to see your child growing what seems to be a second row of teeth. This is actually very common among children. Teeth often grow in like this in the lower front region of the mouth. Why does this happen?

How It Works

Baby teeth are smaller and weaker than adult teeth. When an adult tooth starts to develop underneath a baby tooth, it will put pressure on the roots of the baby teeth above it. This causes the roots of the baby tooth to resorb and disappear. The baby tooth becomes loose and falls out just in time for the adult tooth to scoot into place.

Sometimes, the adult tooth doesn’t form directly beneath the baby tooth. When this happens, it can erupt just behind the baby tooth. This is what can give your son or daughter a few teeth that resemble an unnatural smile, but it’s usually not serious.

What to Expect

As the adult teeth come in, they should eventually migrate forwards and encourage the baby teeth to loosen up. The action of your child’s tongue over time also helps move everything forward into the proper positions. If your child has adult teeth coming in behind the existing baby teeth, you may want to check the baby teeth to see if they are loose at all.

The best thing you can do is bring your son or daughter in for regular dental checkups so that your dentist can monitor the growth and development of his or her teeth. This way, your dentist can more easily determine whether or not to gently remove stubborn baby teeth or recommend another option.
