That's a great question for a dentist (and I'll try to ask one next time I need my teeth looked at)! I'm inclined to say the dentary (the mandible in humans), at least, probably isn't going to change much in response to tooth development. Otherwise wisdom tooth removal might not be a thing, and if it wasn't, having an enlarged mandible (underbite) might pose serious problems for chewing food. But is this true for the maxilla (where the upper teeth emerge)? I really don't know.
Mammals are also weird. (And humans are even weirder forms of mammals.)
Also edited to add: The number of teeth humans have is relatively constant, though there are exceptions (I'm one; I had an extra incisor develop with my milk teeth and had to have that removed).
A slightly horrifying image. But at least it's not centipedes.
