I had a root canal and a filling replacement. The root canal and filling broke off. I will have to have the job done over.He drilled my nerve on the filling, and I felt a lot of pain. The tooth wasn't sensitive before he fixed the filling. I cannot use the tooth now because it is ulra sensitive. My new dentist stated that the tooth is now infected. I would not recommend this dentist to anyone else.I would not be able to trust him to do the job right. don young
