Have you had your wisdom teeth removed?
My daughter had a double set of wisdom teeth. Plus others removed for the orthodontist 14 at one time.
Yep, they were coming in sideways basically. It was actually a pretty decent experience considering the extent of the surgery. I felt so good that night I wanted to go hang out with my friends, but my mom wouldn't let me. :)
When I got braces, I had sixth molars growing in. They removed 12 teeth from my head so they had room. They took the wisdom amongst them.
