I don't know how to tell. I had hoped to eat more tough meat and jerky. I have maybe eating jerky once a week and chewed 2 pieces of Dubble Bubble frozen gum each week. I can't say i see much of a difference. I maybe be getting a few more looks but, i don't get out much. I can say that my jaw feels better - more relaxed, more in a more correct place.It could be from the gum, foods, stress reduction, remembering to relax it, and slide my tongue b/t my teeth a few times a day and at night before sleep or a combination. Yes up and the tip between my teeth. Thank you for the question. I'll chew a piece now and try to do more over the next year. https://www.youtube.com/watch?v=GHseLjrFyCw
