I used to get really bad ones when I was younger, flares up from stress and diet. If you take L-lysene they will stop....you have to use it fairly regularly. Once you start and then go for a few weeks you can cut back a bit. The other things mentioned wil help deal with the ones that you have now. They occur due to a build up of stomach acid....a particular one in your saliva. The L-lysene helps to control that I guess. It has been years since I got one luckily, had one stretch from gum line up past the tips of my teeth on my cheeks the whole length of my jawbone ont he right hand side of my mouth....couldn't even move my mouth for a week, Severe pain..lost a few pounds. That was when my dad died.
Well any ways
