I just got back from having my back molar (3 roots) extracted, with sinus lift and bone graft. The extraction was a bit complicated. The 2 roots that had been possible to root canal, came out with the tooth. The 3rd root, the one with the abscess and crack, stayed in. He had to drill around it to finally get it out. It was an incredibly odd shape for a root. It was very wide, and ballooned out in the middle. The left side of my face is the size of a basketball. He was able to do the sinus lift through the same hole, so I didn't have to have a 2nd cut on the side of my gum. (YAY!) So here i am with a cartoon like velcro ice-pack around my head. When the bleeding stops, I'll be glad. I'm very glad this is all behind me. Thanks for thinking of me.
