I had a root canal treatment redone by Dr Bronson and it was not scary at all. The staff was really professional and Dr. Bronson is definitely very experienced. The procedure was totally painless (even if it's hard to believe if you know how the procedure goes!) and I was comfortable and didn't even feel anything thanks to the elastic protector thing they place in your mouth which isolates the tooth area they are working on. He placed a temporary filing which stayed intact for at least a month or more.
The insurance stuff was taken care of very promptly during and after the work. They are in network with MetLife.
I recommend Dr. Bronson highly.
