You end up sitting through the Iron Man soundtrack TWICE...while they clean half your mouth. And then they insert little antibiotic powder things up under your gums to kill the bacteria that's made its home-sweet-home up there and caused bone loss in your jaw.
Yeah. I get to go back in two weeks so they can do the other side. Which, thankfully, isn't as bad.
Keep in mind, this is just the cleaning part. I have two broken and one chipped tooth, and probably a crapload of cavities as well.
On the plus side, I have the next part of the not!KKBB/IM fic. I shouldn't have any trouble making word count today. Yay.
