Had a very bad experience with him on my root canal. Paid $1000 and he put holes through bottom of my tooth, filled them with a silver material that shouldn't have been used. Never even told me he put holes in the bottom of tooth. Dentist was led to believe it was successful and put crown on tooth. 4 years later eaks around the silver material led to very bad infection. Showers wanted another $1000 to try to fix. Most endontists stand behind their work and don't recharge. I ended up having it redone by another Endodontist who was able to save the tooth. Very bad experience!
