I’ve had one out, and the molar next to it too. both just crumbled due to a cavity that left me with no pain (oddly). Done in the dentists chair, not a hospital. Wisdom tooth was pretty straight forward. no pain in extraction, just serious wiggling with pliers from the dentist for 1/2 an hour. felt odd and a lot of force was needed, but thanks to the local, no pain. Lots of blood tasted though! When the pain killer wore off, it felt as expected. Like i’d been socked in the jaw. nothing that simple paracetamol didn’t fix. Spent the next week paranoid about getting a ‘dry socket’! But all was well. The hole was covered by gum in a few weeks, jaw bone re-grew under the gum in about 7 months.
