Post-op: You had an infection and micro-surgery. Some swelling is to be anticipated. Numbness may be due to the swelling or the injection. Give it 48 hours from the time of treatment. Apply cold compresses 1st day, warm compresses 2nd day. Take all prescribed meds exactly as directed. If problem does not begin to resolve by the 48 hour mark, call your Dentist.
