It's a bit weird round here Alan - Pete needed an extraction a while ago and our dentist said he'd have to refer him to the hospital. A letter came from a Dental surgery, one that's been there years and years but not partic near us so we don't 'know' them. Pete went and they said they were doing work for the hospital. Had a look, had the jabs, he was out again in 10 minutes.
No idea why ordinary dentists can't just do it like they always used to.
Ah - Pete's just wondered if normal dentists are not Dental Surgeons any more, only Doctors?
