Have you contacted your dentist Bex? Seems odd that this problem has occurred 2 months after the dental work. Did you eat or drink something that could have triggered it? I have a tooth that's been niggly since my amalgams were replaced; it hurt a lot and was very sensitive for a few weeks afterward; and now 6 months later I can still feel it occasionally, especially if I bite down hard with it (ouch). My guess is that the drill must have got close to the nerve.

Since it's only been a few days, I wouldn't get too frightened, and it might help to talk with your dentist. If the pain carries on then you could look at options, but one step at a time. Sometimes pain near a tooth isn't toothache at all, but neuralgia, or a bacterial infection.

Wish I could help more. I hope the pain goes away soon and that you're able to get on with things without having to worry.
