Your tongue...if it rests like that you definitely need myofunctional therapy. I certainly wouldn't advise any treatment plan which would reduce your oral volume with such a large tongue and small jaws. Definitely don't pull healthy teeth. if you have impacted wisdom teeth, that's something else to consider.

I'm still looking into the DNA myself, but if your need is critical I'd say give it a try before undergoing more invasive treatment, like surgeries or braces that just shuffle teeth around.

Be sure to get more opinions from consults before making any decisions. Get an idea of what type of treatment you'd like to occur, and start asking in consults for advice on those topics and if they know of anyone doing that type of work. Sometimes it requires networking through physicians to find people because they don't advertise their practice or are in an academic setting.

where  do you  live?

and i heard that homeobloc and bioblock are a bit related to the DNA appliance so maybe if you couldn't find a DNA appliance you can go with one of those
