As long as your daughter doesn't go around sticking her toungue out and showing it off she shouldn't have a problem.
I think this practice is just disgusting and makes the girl look like she's "on the make". Is she trying to pick up extra cash as a hooker?
Around here, a lot of places would not hire anyone wearing this extra hardware. Restaurants that I frequent make the girls take these things out or cover them up. I see one young waitress who always has a bandaid on her eyebrow. I asked her about it and she told me that the manager makes her cover up her eyebrow stud when she's on duty. Another restaurant I knw makes a young waitress remove her nose stud when waiting tables.
You'd think these kids would get the message.
