I have a massive cavity in my rear left wisdom tooth. I know the nerve has already died, and now I’m in a decent amount of discomfort, a couple-few weeks later. I have a prescription of amoxicillin, but the surgery isn’t for another month, so I don’t want to take it too early.

Is this discomfort maybe more nerve pain? Is it infected? I grind my teeth in my sleep too. I know that doesn’t help.
