I went in for a filling which she later said if she drilled any more it would have been a root canal (meanwhile i kept hearing her say "I don't see it")... I don't know what she meant by that but I wish she would have just done the root canal and got it over with. I'm in pain now on a tooth that wasn't bothering me to begin with. I went back and saw her associate because of the pain and she spotted a small cavity in the tooth next to the one Dr. Mezcua did the filling. The tooth I told her was bothering me every time I flossed. Now I have to wait 2 months before I can go back to see her. Not happy what so ever! I'm looking for a new dentist.
