I had mine pierced for about 3 years. Surprisingly, actually getting them pierced was not so bad - adrenaline and endorphins kick in within about 0.1 second, and the pain disappears quickly. I was sore for a few days after I got them, but I took really good care of them, and they healed up nicely. It was a lot of fun for my boyfriend and I to have them, and no, teeth were never an issue. I definitely caught them on things more times than I can count (I am
super clumsy) and while this would make them sore for a few days and require special care, it never ripped them out
I finally ended up removing them because had gotten back into competitive swimming. The racing suits would show them, and the daily hour-long exposure to chlorine was drying them out
very heavily. As a result, they started to reject, and all attempts to rectify the problem were fruitless. I ended up removing them and it was like losing a body part. I still miss them terribly, but re-piercing through the scar tissue is usually much more painful, and generally not successful. Anyways, I would HIGHLY recommend you get them done - provided you are not a big swimmer that is
Also, even if you are, you can wear these:

A little expensive, but I would have given anything to know about them before this happened.
