Sorry, I should have been more clear...my problem now is a little different, bar length is fitting okay for my still swollen lip but it's creating a nice little abscess where the bottom of the disc rubs at the webbing between my lip and my bottom gums. My swelling has gone down some but not -much- and so I'm thinking I'm facing another week still before I can get the bar downsized and just looking to create as much comfort as possible for that time. So I was wondering whether the PTFE was safe and it seems not, so I guess I'll just grow some balls and tough it out :D
While I'm at it, do you think it's wise/safe/possible to cut/sand/file part of the disc of a bioplast labret bar? I'd be trying to get more semicircle type shape, with rounded corners. I'd imagine I'd have to get the edges really nice and smooth but is that going to mess with the safetyness of the bioplast?
