You should go back to your dentist and let him/her check the situation. Your dentist might recommend a more effective pain reliever than the one you are using or he/she might tell you to continue taking the antibiotics for a couple more days.
I'm taking both antibiotics (Amoxcillin 500g) and pain meds(Motrin 600g). Will this help get rid of the pain? How soon will the pain go away, because I missed two days of school already, I don't want to miss more.
You may want to contact your dentist and find out if you have dry socket. They usually will pack the socket with some medicine to help alleviate the pain. Are you taking any antibiotics or pain meds?
