What to do if i have numbness after wisdom teeth removal?

Numbness: If the numbness last longer than 3 hours post op (id does not go away) you need to return to the oral surgeon ASAP. Paresthesia may last 6 wks to 6 mos or be permanent. The sooner it is diagnosed the better the outcome and sometimes micro surgery is needed to reattach the two ends of the nerve if the nerve was severed. pinched/crushed nerves recover w/o surgery.
