A few ideas:

• It would be easier to assess your issue after seeing front & profile pictures of the bottom two thirds of your face.
• 49 mm is a wide palate. It's possible that this is your full potential.
• Asymmetry is not necessarily lack of development, but only lack of symmetry. In order to fix symmetry, Mewing blindly is not enough. You have to systematically search for asymmetrical muscle usage within the area of tongue, neck & shoulders. It may be that the lateral pressure of posterior tongue is not symmetrical. Your current neck/tongue posture may FEEL balanced but only because you are used to the sensation and the specific muscular compensation. Experiment with mewing as much towards each side individually as you can. The side that feels more straining in the skull should be your lacking side. It can be hard to determine the nature of your asymmetry just by looking at your reflection, because the maxilla may not only be asymmetrically developed, but asymmetrically positioned too. This can make it seem like the truly weaker side is actually your better side.

Cheers for the response, I experimented with mewing 'more' on either side of my palate and from what you describe it does appear the side I think is weaker is indeed. When I press more on that side than the other I certainly feel more strain on the skull as opposed to when I repeat the same exercise on the other side. How can I go about realigning these muscles to the correct position then? Just press more on the weaker side of my palate until it catches up?

In regards to palate width, I'm not convinced 49mm would be my maximum. On my stronger side it still appears there's 2-3mm of expansion to go as I can see my bottom row of teeth at the sides of that half would be much better aligned if only the palate were wider (I've already seen evidence of this from the expansion I've already gotten). What I'm aiming for is the palate of the ancient skull shown in mew's museum trip video, but I'm not quite there yet in either flatness nor width.

Also do you have any advice on how to keep my teeth together whilst I sleep? Oh and I'll provide pics of my mid and lower thirds when I get the chance.

What do you mean by 49 mm being his "full potential?" Id imagine that constant pressure to the maxilla would continue to cause bone growth. Its not like osteoclasts and osteoblasts "know' when to ignore pressure changes. Perhaps due to the new shape of his face he simply needs to apply different vectors of force with his tongue to see continued changes.

I say all this because facial skeletal structure can change drastically from a tumor or growth under the bone into a completely deformed shape, so don't see why the bone would stop changing once its "done"

Focusing on the weaker side is a good step to begin with. As for keeping teeth together during sleep, some sleep with the jaw against their fist, others try to keep their heads tucked in in a way that pushes the mandible against maxilla.

 I am referring to sutural growth. The bones of the skull are in complex dynamic relationship with each other. It is unlikely that you will be able to keep on expanding forever without encountering resistance from the rest of the skull. Beyond sutural growth, bone remodelling is certainly still possible. But it is also a significantly slower process.

Have you started fixing your posture for the rest of your body? If the muscles of your head and neck and tight then they will hold the bones in place. So your tongue is pushing out but maybe tense neck muscles and reigning the whole thing back in

I am the exact same issue of a canted maxilla, however i am currently in braces which are due to come off very soon. @canted have you had any more progress?

@Progress, you seem very knowledgeable in this area. I too have what feels like a canted maxilla (one side of the roof of my mouth feels lower when i press my tongue on it) on this lower side, my lips, cheekbones and eyes are lower too. I am extremely worried as my orthodontist refuses to acknowledge any of this. my braces are due to come off soon, ive been mewing with braces for months and am considering not wearing any retainers atall once my braces come off so i can correctly mew.

If your ortho recommends a Hawley retainer, ask for another option as those just hold everything in place and don't allow tongue force to be applied since they cover the area where your tongue would be.

Now, I would focus on things like chin tucking, pulling back your occiput, keeping your shoulders back and your chest high. No slouching. The straighter you make your posture, the straighter your posture will become. 

Braces can't fix canted smiles since canted smiles aren't caused by tooth position but maxillary tilt and braces can't tilt your maxilla. Check your face and see if you favor one side over the other in terms of muscle tensing. I have tensed the left side of my face for over 30 years and just recently realized I was doing that so I stopped. I noticed my left side of my lip had a tendency to a somewhat smirk when I looked closely. So I relaxed that left side and immediately some of the asymmetry was corrected. However the tensed muscle put grams of force for decades on my maxilla which is why it pushed it sideways and canted my smile. At least now the muscle force is gone so the problem can't get worse. 

"braces can't tilt your maxilla", braces with elastics pull the maxilla back and down
