If it was causing me serious pain, suffering, etc., I would be much more motivated to do something about it, honestly. But it isn't, so I don't.

It is my only phobia and not making any particular impact on my life -- anyone who goes "oo, I don't want to talk to her, she's got a funny tooth" will probably have been put off by the "eek! she's not wearing makeup!" or "the world's coming to an end, she weighs too much!" already. ;)
