The info sheet I was given said not to rinse for 24 hours and I followed it.
With this tooth, the decay was deep. A lot of bone was removed and a bone graft put in for an implant in the future. Could all of that have something to do with the pain lasting longer? In comparison, I don't even notice where the two wisdom teeth were removed and there was very little swelling with those.
Resist the temptation to feed the trolls.
