I was supposed to get a regular root canal. This went very wrong. The nitrus gas machine vacuum sealed my nose, which is now purple and swollen. And this was one of the most painful appointments ever. They pushed and pulled on my mouth nicked me with their tools and in the end gave me a partial root canal, whatever that is. Now I need to go to another dentist to finsih what they started. Also I told the hygienist she bruised my nose and she didn't act like anything was wrong.
