Jaffa Cakes and Sodomy

My bottom gum appears to be receding. I think I know why - there was a kissing-related incident a couple of weeks ago with my labret and the area's been hurting ever since but still, yikes. D:

Anyone know what I can do about it? I looked on BME Wiki and someone mentioned that using a CBR instead of a labret stud could stop it rubbing against the gums and prevent further erosion - think this is worth a shot? Any other ideas?

(visiting the dentist isn't an option right now - I'm not registered with one (still on a waiting list) so can only get treatment for emergencies)
