When my bottom wisdom teeth came through. I used to get a pain up the sides of my face and in my temples. The dentist said it was because the tooth was impacting on a nerve, and there also wasnt enough room for them to come through. So I got reffered to the hospital to have them out under local anasthetic.
when i saw the dentist at the hospital, he said it had to be done one at a time under local anasthetic, which was a bit scary as Id never had anything done, not even a filling and was starting with a tooth extraction, awake.
About a week later I got a call from the hospital saying the surgeon had free theatre time if I could do it at short notice. I agreed,and went for my pre op. The surgeon said he had already looked at my notes, and that the previous dentist was "an idiot" and that he had already booked me to have it done under a GA at a private hospital the next day.
When i woke up, my face was VERY numb to the point i couldnt speak or eat. I decided to rinse my mouth out when i got home. Apparently this is NOT to be done.
All was well the first night, till i woke up with the worst pain in the world which went on for 2 solid days of no sleep, and when I went back to the hospital it turned out i had flushed away the clot that seals it, and ended up with something called "dry socket" which was painless again after the surgeon packed it.
So as long as you dont rinse your mouth you should be fine!
