I had one on the top of my lip last year that saw so big the mouthpiece was sliding off its placement into side location. It was very painful and disruptive for about a week. I did try the advice given here. I used a tweezers to pluck the hair out of the middle then put a bandaid with alcohol on it over night. I kept practicing with the more side location until I coupld place the mouthpice where it really belonged.
