Re: Pain after tooth filling
Two things come to mind. First, the pain may be because you had to hold your mouth open for an big longer than usual. The jaw muscle may have gone into spasm. This should resolve itself in about 7-10 days. Try using a warm compress and some gentle massage at the jaw angle. Some people try gently chewing gum.
The other thing is that the filling, because you mentioned that it was a large one, may have come close to the nerve. This "may" resolve itself when the trauma from getting the filling goes away. Or, it is possible that the nerve has been disrupted, which can easily happen with a large filling, and you will need it a root canal on that tooth.
If you can take an anti-inflammatory, like ibuprofen, I would try that for a day or so, but if the pain is still there after a weeks time from filling, you need to get back to the dentist for a reevaluation of the tooth.
Good luck. I hope all your pain is just from the trauma of the filling and will be gone by the time you read this. Do let us know how you are.
My very best to you,
