When my front tooth crown came off, he replaced it with one that was too long and caused me to bite down on it constantly, causing bruising and pain (apart from the cosmetic factor). He said, I would "get used to it". Also caused me to have to have an emergency root canal, when he dismissed my molar pain and sent me back home twice (in spite of appointment!), due to over-crowding and over-scheduling. A horrible, horrible experience!
