He performed a crown fix on my top front tooth. As a result of trying to fix the crown, he could not manage to get the crown to place properly. As a result, my bite was off, so to fix his mistake, he started to grind all the tops of my lower teeth to fix the bite - UNBELIEVABLE!! . HE USED NO NOVACAIN and the pain was excrusciating. I thought I was going out of my mind - felt like Dustin Hoffman in the Marathon Man. Screaming with pain and white knuckles to the chair I tried to shout STOP!! It just made him angry. I came very close to punching him in the face - and I am NOT a violent person. This guy should NOT be practicing dentistry. Now I have permanent sensitivity in all the top of my teeth in my lower jaw because this idiot filed away all the enamel that was there. It's been 2 years and my teeth are still over sensitive. I can't eat ice cream or really cold drinks anymore because of his work. WARNING: Do NOT go to him unless you are into torture and pain. The worst dentist EVER!!!
