I can hardly count the number of time I have taken a bite of that delicious slice of pizza and burned the roof of mouth, resulting in a blister. For days I was unable to eat anything else that was hot without reliving the burn. A trick for easing the problem is sprinkling your tongue with a pinch of sugar and holding it against the sore spot. According to a study I read, it seems that as the sugar melts, it stimulates the brain to release endorphins that make you forget about the burn. I tried it and it really worked, however, when the sugar was dissolved, the pain was still there but significantly less. Next time you burn your mouth, try it. What do you have to lose?
