They don’t, I have been referred and sedated. It’s not an easy process. But potentially my only option.If your as bad as that then asked to be referred to the dental hospital for sedation.I dont think they do this now at normal dentists because people have died in the past under general anaesthetic. I'd get your dental practice to refer you and ask them how long the waiting list is as well. Things have changed with all this covid crap as well. x
Sadly one of the main reasons they aren’t allowed to anymore is a lot of dentists were caught out for molesting patients under sedation.
