I had a bone graft on the lower right jaw and three screws placed for implants three weeks ago. I still have swelling and pain?

I'm sure that you have dealt with this problem long before reading this, but for anyone experiencing similar problems, I would suggest moving the appointment with the surgeon to an earlier date. The first rule in my practice is "no pain". I learned long ago that people do not like pain and neither do I. So I take pain very seriously. If you experience unexpected pain, contact your doctor immediately.
