First, go to a regular dental institution. Extra teeth hinder orthodontics, so it is necessary to extract teeth. ? Some people have never pulled out more teeth in their lives, and there is no problem in the end. Some people end up with tooth cysts. Didn't see the baby's teeth? It's hard to judge. If the position is not difficult to pull. Let's pull it out. If orthodontic treatment is forced without extraction, normal teeth will not move to the desired position at all. Maybe it won't cause absorption at all.

This is the X-ray of supernumerary teeth I found on the Internet. If your child is similar to this tooth, it is necessary to pull it out.

Is this my humble opinion? hope this helps
