Because it's bloody killing me!
The gum doesn't look red but the tooth is growing outward into my cheek (been like that for yrs)and it's very very sore.
It's been like this for a few days, and will from past experience will get easier/less painful over the next week, then in a month or so will happen again.
This time though it's the worst it's ever been.
I have a check up at the dentist next week (coincidently).
