I had upper jaw teeth extraction and bone graft surgery,i was feeling better.now after10 days the gums are swallen, is this normal?

Possible infection after this amount of time. See your doctor for exam and treatment. Don't take any medications on your own.

May be infection. zReturn to the practitioner that did your surgery. He/she is most familiar with the reasons for your surgery and the procedure itself. He/she is also responsible for the post-surgical care for which you have already paid.
