Review (5/5): Using for Years, Only Thing That Works Every Time
Been using this for years, for my mother, father and me. It is the only thing that works every time. Have used Western stuff like Orajel and Kanka, etc. This works absolutely. I use Gly-Oxide a lot as antiseptic for gums, it works well, but when a canker sore persisted, I returned to use Watermelon Frost to take care of the problem.
I apply it directly from the puffer bottle, rather than put on finger to apply, or cue tip or as mouthwash--as mentioned by others. It has a bitter weird taste--but adapt to it since it really works.
Of course they should improve upon this crude method of dispensing--but heck, the stuff works so put up with it.
