The only person I know who had anything like that, got it because she ground her teeth REALLY badly when sleeping. (A bit like CA does, actually!! LOL! )

Unfortunately, she had a "thing" about having things in her mouth (yes, THEM too, so she said!!) and had to give it up after less than a week! Stopped her grinding her teeth, but only because she couldn't get to sleep!!!
