I had a number of cavities filled on my right side of my mouth. A month later they continued to hurt so I went back and she filed down the resin. She didn't seem overly conserned with the pain. Luckily insurance changed and I went to a different dentist that found 2 cracks b/c my bite had changed with the fillings and after the temporary crown did not work, I will be going back for a root canal b/c the filling was done too close to the root and it irritated it. So now my simple filling has resulted in a number of headaches and extra money to fix Dr. Ruzicka's mistake.
