Mine was horizontally impacted against the next molar too, mine remaining teeth were the same way. They were a little loose for a week or so, then they stopped "drifting" and set anchor again. Glad that yours was stitched up. Mine had stitches where it was backed into the back of my mouth, but not where the tooth erupted from.
You sound like you aren't such a good candidate for dry socket. That's good.
You'll heal really fast if you were a good bleeder the first day. Those blood clots are already probably granulating into tissue.
Sounds like everything is covered up that needs to be. Glad to hear it.
They say vitamin C helps the granulation of new skin.
And they say try to keep getting nutrition too. I stopped drinking alcohol for a couple weeks, and that helped too. (Back to drinking now, YEAH!)
Good luck. I had to check back and see how your pain level is. Tomorrow and Saturday will be key. If you make it through the weekend without developing BAD pain, you should be out of the woods. You'll know. It won't be that soreness kind of thing. It will be like a root canal, only worse. Watch those lowers! Only about 5% get dry socket, so your chances are good.
