There is a definition about dental care services and what that encompasses. It does not encompass the mileage, for example, that you used in your example. It is really meant for the services that a dentist, a denturist—that's probably less likely for children—or a dental hygienist is lawfully entitled to provide.
It goes on to explain that it could be for “oral surgery and diagnostic, preventative, restorative, endodontic, periodontal, prosthodontic and orthodontic services.”
