The injection of Botox and Dermal Fillers can cause serious problems as in blindness and skin necrosis as well as foreign body reactions. A week end course is not sufficient training. Only a Board Certified Facial Cosmetic Surgeon should be able to provide these services. To allow a  dentist to do so would be dangerous for him and his patient. These procedures are OUTSIDE the Oral Cavity and no Restorative Dentist should be allowed by the Board of Dentistry to do so. This would also result in a response from the Medical Board.
