What If My Child Has Two Rows of Teeth?
Why does it look like my child has shark teeth? As pediatric dentists, we hear this question frequently.
When a child reaches school-age, the permanent front teeth begin to erupt. In a previous blog post, we discussed the average ages when the permanent front teeth are supposed to erupt.
The theory is that when a permanent tooth erupts underneath a baby tooth, it is supposed to resorb the root of the baby tooth which is why the crown of the baby tooth eventually becomes loose and wiggles itself out (sometimes with a little help from the parents!).
Sometimes, the adult tooth erupts in a different location than normal, and therefore does not do its job of resorbing the baby tooth root. In this case, it may look like your child has two rows of teeth, one row of adult teeth and one row of baby teeth.
If this happens to your child and the baby teeth are very loose, by all means, go ahead and wiggle the row of baby teeth! If the row of baby teeth are not very loose or you are having difficulty wiggling them out, contact your pediatric dentist. It is important to wiggle the baby teeth out so that the adult teeth can move forward into their natural position. If the baby teeth are left in place for too long, this can lead to crowding, rotations, and problems with how your child’s teeth function and fit together.
So if your child’s teeth resemble a shark – no fear, it’s not as scary as Jaws. Hang in there, and make sure to ask your dentist any questions you may have at your child’s next check-up appointment.
