I was wondering the same thing myself as I am due to get a partial for three spaces all together. Just reading about wearing partials or fulls gets you all freaked out as they talk about not having that natural chewing stimualting pressure there on the bone. Besides exercising and eating your greens, collards and all that, I am wondering about things like -sounds weird- electrical pulses...i've read that this actually stimaulates bone growth and I don't know if my face zapper for wrinkles counts, but you've probably seen them, they've been around for a while. there is a small micro-current that runs between two round metal disks, you put your special creamy goop on your face and then hold the machine on several key muscle points and it stimulates thos muscles, to firm and lift. But I did read an article about how small electrical current stimulates bone...however....holding the machine on to a gumline is a whole different situation, perhaps holding along the areas closest to the mouth? I'm now officialy curious and am going to present this question to a website I go to for oddball questions like this. Will keep you all posted in the future.
