Bad Dentist.
I arrived for a missing filling that fell out of my tooth. All I wanted was the filling replaced. To do so the dentist drilled my tooth in place to fit the filling. However the dentist drilled so deep as to gut out the entire tooth. The tooth was like an egg-shell when he was done. Thereafter, he placed a filling right on top of the nerve within my tooth. I felt the pain and he told me that it will pain for a few days. I asked why would he not fill up the rest of the egg-shell with filling so that food would not get stuck inside. He did not want the filling to get pushed in.
A month or so later - NOW that the filling is pushed in on top of the nerve I'm in pain. I went back and he said "you will need a root canal" because the filling is touching the tooth's nerve!!! He wanted to pull the tooth!
I should have known I was in a bad place when I walked in and the smell hit me in the nose. The equipment is from the 80's. I am a business man myself and would never rate a business as bad unless they are fully capable of giving very bad service. Unfortunately, I will need to go to another dentist to fix the issue and bare with the pain. No one else should need to do that.
