1 /5 Gill Cornell: My visits with Dr. Mattia were extremely painful. I understand that there is some pain with dental work, but this was unbearable. There was also serious damage done to my teeth by Dr. Mattai. Dr. Mattia installed two crowns in for me, causing nerve damage to both teeth. Due to the damage I needed root canals in both teeth. Naturally, I did not go back to Dr. Mattia. Both root canals were done by a new dentist. This new dentist also installed the replacement crowns. I called Dr. Mattias office to let him know what happened. I did ask for a reimbursement for my out of pocket expenses that resulted from the two root canals. His secretary simply hung up on me.
