Usually they give patients antibiotics and pain medications. Some pain and swelling are to be expected, but if you think it's more than expected or you are not on antibiotics, give the dentist a call to report your symptoms.
Oh yeah, get back to your dentist and get some antibiotics. Its also possible that you could have a strained muscles. or jaw problems, from keeping your mouth open for long periods of time. You want to make sure you don't have infection from the dental work, If it's muscular, then you do some hot and cold packs. In the mean time, try taking some advil, if you can take it. It will work the best to help with pain and any inflammation that might be present. Good luck and hope you feel better soon.
