I don't know. I am not a pediatric dentist. There are things that can be related to later teething (health conditions, etc.), but I don't really know the answer to that. I can ask one of the pedi dental profs here and PM you.
Ok, I am not even a general dentist, so I don't see young kids in my specialty practice at all (or very, very, very few). But now I will probably have to find out for my own curiosity.
