thanks for your query, i have gone through your question, the swelling following surgical removal of wisdom teeth is normal, it occurs due damage to lymphatics while removing tooth..the function of lymphatics is to remove the excessive fluid from tissue spaces...so in case of damage to these structures will result in swelling...it will take 2-3days to recover...even the removal of the bone while removing tooth also causes swelling pain and limited mouth opening...nothing to worry..it will come down in 2 days...just take the medicines prescribed following extraction...take soft diet, do saline gargling 3-4times...dont apply pressure on swelling by touching that area...instead of normal pain killer you can take tablet enzoflam which contains an antiinflammatory also which reduces swelling...wish you speedy recovery..i hope my answer would help you... take care...
