First off, I had a question regarding the FAGGA device. In the picture above we see both a green piece of plastic pushing forward on the palatine ruggae, and pulling the incissors forward. I was wondering if the green plastix pushing alone would be enough to create similar, or close to similar results.
if that be the case, then would be beneficial to push the tip of the tongue both upward and forward?
As Newton said about force... opposite and equal. So.. if the pressure is from the tongue... then the tongue is getting pushed back. This tongue pressure is why many end up with curve of spee. The mandibular arch bows under the pressure. With CDA, the pressure is distributed to the roots of the back teeth.. They're in a row / strongly anchored. So... yeah... I don't know how much FAGGA works with adults, though, because I haven't studied it. I'm going to assume so since many adults here talk of it.
For kids... they have something like this... called a distal jet... http://family-ortho.com/orthodontic-appliances.html At a certain age it moves molars back into the face more.

Under the pressure of what?
You often mention Spee's curve as an argument against mewing. Are you aware that Spee's and Wilson's curves describe natural and desirable shapes? A completely flat occlusion would generally be more dysfunctional than a mild Spee. Moreover, both these curves are part of Dr. Monson's Spherical Theory of Occlusion that has been around a long time:

Based on the face pic you posted on your site, it seems unlikely that you had the "perfect occlusion" you talk of. Your teeth may have fit together well, but since your face itself is downward grown, no state of occlusion can be anything but compensatory. Note that there is a difference between perfect occlusal appearance and perfect occlusal function. What I suspect happened to you was that a) you had begun getting actual results from mewing, after which you panicked out because the occurring change was not an unequivocally positive one straight out of the gates, b) you mewed in some bizarre way. The few words you have shared about your technique in various posts so far (pushing the jaws apart with the tongue) suggest that there is something wrong with your understanding of the tongue posture. Rather than telling everyone not to Mew, why not describe your technique in detail and help us figure out whether it's you or Mew's principles that are in fault?
