A few months ago I had root canal treatment on a back tooth which had broken in half, but still had problems, so then had a crown fitted. It's never felt quite right since.
Today a v large lump has appeared in the gum at the side of the tooth and I think my cheek is beginning to swell .
I assume this is a dental abcess, so need to get to dentist asap, antibiotics etc.
Should I just get the crown and what's left of the tooth taken out, or can it have another crown?
