I'm musing about how it will feel. If you open the rear of your jaw so that your back teeth are open but your front are relaxed you get quite a strong pull in the jaw. In honesty its something I should imagine most people could do with facial exercises but I don't really know enough to comment in a concise way. I am always up for an experiment so I'll give it a go. I want to go for the least elaborate package they do as I think all the photos and micro imaging plus multiple return visits are total overkill for them to make money and monitor your progress for their own interests.
