It is pretty absurd to think that there is any justification for misleading the public and allowing a general practitioner (or even for a specialist advertising outside of their specialty) to falsely advertise expertise in a specialty field without graduating from an accredited residency training program.  Patients, their families (parents), and even their insurance carriers are paying specialist fees, investing their time, money, and trust into that dental practitioner, with a certain expectation for level of care and competence.  It's practically fraudulent to market and advertise for patients to come receive dental care at an orthodontic practice and not be seen by an orthodontist, or go to a pediatric dentist and not see a pediatric dentist.  If a general practitioner wants to offer those services outside the scope of their typical training, I think that's up to them and their comfort level, but they certainly should not be able to mislead the public and advertise as a specialist.  Would you be upset if your brought your child with heart disease to a cardiology practice to be evaluated by a non-cardiologist?  Or would you trust the care of your loved one undergoing chemotherapy at an oncology practice to treatment by a non-oncologist?  Seems obvious to me, but if we allow this type of deceit and misinformation to become commonplace, the already skeptical public will lose even more trust in their healthcare practitioners.
