I know I'm a bit l8 with this post. I had a wisdom tooth out & got no pain killers. Was told to rinse with salty water. I smoked few mins b4 going dentist & smoked straight after (weed that is). I had no pain wotsoever & got no infection. Also did the same when I had a route canal done 2. As long as u rinse & get the food out then all's good
