Does that mean that Mr R would have commited an offence if he'd tapped on your sore tooth then prescribed you antibiotics?
Yep! Daft, isn't it.
I suppose you could try to get me struck off then
I confess to having tapped on infected teeth and prescribed antibiotics for them.
I have also lanced a dental abscess.
I have done other emergency dental work; it's much more rewarding than spending hours on the phone trying to find someone who is either going to do precisely the same as I would, or advise the same.
