I had one out last Friday. A bottom molar that had broken with a bit trapped against one of the facial nerves and another bit looking like it was stuck in my jaw grrr.
A surgeon did the op in the end and it's healed really nicely. I posted about the hole too because I was worried. If it helps this is the way it healed...
day 1-2 looked v black and bloody, kept bleeding a lot
day 3-5 some white stuff appeared on top of the clot and I was worried it was pus/food. Posted on here about it! Seems it was just part of the healing process. Still looked all clot like though.
day 7 for the first time, the gum starts to grow about and it stops looking like a crater and a bit more like a normal gum. I guess the white stuff was new skin/gum forming.
Today, 9 days later, it is starting to heal over very well - it's not flat yet, still a hole but the colour is better.
It's still too sensitive to eat food on - I accidentally crunched a nut in the hole and it was sore grr but other than that, I think we're nearly there.
I was also worried about dry socket but did all the salt water rinsing and that seemed to help. Hope it is ok for you and everyone!
