I had a root canal by Dr Mangin. First of all he was arrogant from the get go. I felt the procedure was rushed. Two weeks later I'm still in pain. I called the office several times and expressed my concerns. I was told It's still Normal to be this sore! (2 weeks out!?!) Finally they agreed to see me. To my surprise He didn't see me at all. He had an assistant (who looks 17 and not qualified) see me to adjust my bite.(which never helped the pain by the way) I paid $1,200 out of pocket for horrible patient care. Now I have a hard lump on my gum by the tooth that was done. I'm sure it's infected. I feel this office is very unprofessional poor patient care., and rushes patients in and out. I will never return to this Dr or office. And will never recommend them! Horrible experience!
