Normally I wouldn't continue, but the owner's response in my opinion is deceptive. It is not a matter of whether or not the filling were needed due to deterioration. They were not needed. Comprehensive care seems to mean to Dr Suffoletta, replacing solid silver fillings in the back of your mouth with shorter lasting cosmetic ones. If it were me I would increase training and/or let the customer know that they have other options. Some folks might want the service he provided to me. I wouldn't have allowed the work to be done if I had all the facts.
