Dentists will usually offer a prescription of Vicodin or something if you want it, but it isn’t really necessary to take something like that. Take a double dose of Ibuprofin (Advil). It will help the pain, swelling, and temperature with no side effects (for normal people not on certain medications and without certain health problems). It will make everything tolerable. You may need to be on antibiotics, as well – ask your dentist. Be careful to avoid sucking or anything that causes suction in your mouth. That could cause the clots on your lower jaw to pop out, thereby exposing your bone to infection (dry socket). If you were to end up with dry socket, the pain would get much worse.
