If it is too far fucked for a dentist to remove in the chair, then presumably it needs to be removed under general anaesthetic.

Given this, then it will need to be in a hospital irrespective.

Your only alternative given this will be private, which will cost a lot of money. Is she on antibiotics? If it is a lot of pain, it may be infected, in which case the infection will need to subside before they do anything with it anyway.

I am of course neither a dentist nor a doctor. This is just my opinion.
