My periodontist said I need a root amputation on a back molar that has already had a root canal and crown. He said there is bone loss in this area and periodontal disease(only on this tooth). He said it would cost 2,400 dollars (possible bone graft). From my research this price seems extremely high. Also, I am not comfortable with cadaver, or bovine graft. Is there a synergic option? And what do you think of the cost of procedure? What about the risk? It is an upper molar and my sinus is close to area so dental implant might not be an option.
