A dentist is just someone who has undergone 6 years of training on how to use a screwdriver to remove a tooth, and use some glorified polyfilla.(*) The last extraction I had was done with something not disimilar to a bradawl. Completely and utterly painless though.
(*) I jest about their training.
I thought I was doing badly in having not been for a bit too long, until I got toothache and went to see the dentist. Eventually it had to have the root canal done.
Anaesthetic failing to work: not good.
Root canal is easy. Any pain I had during my root-canal was nothing in comparison to the pain I was in pre-anaesthetic. And until you've spent two 6 hour sessions in the dentist's chair having *major* dental work you really don't know what pain is. I can't begin to describe the pain in the gums that comes from having 40+ injections to put in 10 crowns. Or the pain in the jaw muscles from holding your mouth open for 6 whole hours.
As I said, a simple extraction, even if it's bits of a tooth, should be nothing more than painless. If it ain't then find a new dentist. Teeth don't fix themselves, it's worth getting it done properly, but there's no reason that means £££.
Mersey 24 you say?
Well done mattc! Chapeau!
