Our daughter will be getting her gums cut. Yes, cut. It seems that a canceled appointment (fam. emergency) lead to cavity, which lead to tooth being pulled, which lead to space maintainer, which lead to some calloused gums, which has lead to needing to cut some of it off. Did you follow?
Our son has a small jaw (my side of the family), and the potential for a big under bite.
He is going to be getting an enhancer (forgot the real name.) then braces. This is to hopefully prevent him needing jaw surgery in his 20's.
