I have all 4 of mine. The top 2 are fully grown in, the bottom 2 are still halfway under my gums. Sometimes they try to push up and it kinda pulls on my cheeks and then my teeth rub against them and causes sores.

I'd really like to have them pulled.. Last time I went to a dentist, I was told not to unless they really bothered me cuz it could cause my teeth to shift & ruin the work my braces did. They look gross, though, in spite of my taking care to scrub them really good. I'm sure having pretty well brown teeth in your head isn't exactly healthy. lol
