General dentist = do everything you want. No rules saying you have to refer anything. You want to do a crown, do it. You want to place an implant, sure. You want to do a cleft palate closure, 5 rooted 3rd molar endo, orthodontics, sinus lift, botox, sure. Just remember, you are liable for all you do whether you are fully trained or just think you are.
Specialist trained dentist who chooses not to advertaise as a specialist = do everything you want. No rules saying you have to refer anything. You want to do a crown, do it. You want to place an implant, sure. You want to do a cleft palate closure, 5 rooted 3rd molar endo, orthodontics, sinus lift, botox, sure. Just remember, you are liable for all you do whether you are fully trained or just think you are.
Specialist who advertises as a specialist = do what is confined to your specialty and not supposed to do general dentistry that does not pertain to their specialty.
There is no rule in dentistry that you must refer anything except that ethically we are bound not to do what we really have no training to do.
