This is kind of an odd question, but I had a cavity in a tooth when I was in my low teens and it was filled. The dentist said I'll need to have my wisdom teeth pulled and a cap or root canal on the one that had the filling in the next couple years. Is it possible to pull the cavity tooth and allow the wisdom teeth to fill in there? Is there someone out there that knows? I know that you don't have to pull the wisdom's if you have room in your mouth, but can they be moved in to fill in for the teeth next to them?

You should ask the dentist if the reason for removal is due to how the teeth are laying in the mouth: i.e. sideways, if they are sideways, if they can be moved to a proper position, or if the reason for removal is only due to overcrowding.

Also, if you have already had orthodontic treatment, you may want to ask what additional orthodontic treatment might be required to keep your bite aligned if you decide to have alternate teeth pulled.

Many people have teeth (other than their wisdom teeth) pulled to help prevent overcrowding. I did, but I also had my teeth pulled prior to when I began orthodontic treatment.
