What do you suggest if my teen daughter was told 8 of her adult teeth didn't grow, 4 being her wisdom teeth.?

No wisdoms not bad.: Some people don't develop wisdom teeth which isn't a bad thing since they usually have to be removed. As for the other 4 missing adult teeth; this is not an uncommon occurrence. There are usually two options. If all else is ok, the baby teeth can be left and kept for many years. A dentist would have to evaluate that decision. The other option is to see an orthodontist for an evaluation to remove.
