This mouth guard is working. I’ve been testing it for the last 2 weeks. Molding went pretty well. The snoring is vastly improved and I’m sleeping better with no dry mouth. I am using the first band and can go up in shift if needed over time. It is definitely helping with mouth breathing. My husband also agrees it’s working. That is the true test. I am considering a dental one that is personalized to my mouth for long term but wanted to make sure that shifting the jaw was what I needed. Doctors have been no help. This is a personal trial and error before going to a cpap. I’ve tried so many other mouth pieces. Don’t buy the AIRWAAV. I would absolutely try this before any other products. It’s an affordable appliance with molding. No bad taste or smells. I hope this helps someone else who needs to shift the jaw open to keep the air flow path open.
