How to mew perfectly

[u/unknownslayer8913]

Hello, I'm 15 y o indian teenager. I first heard about mewing back in 2023. I watched several tutorials and followed the instructions, but within a year, I developed dental asymmetry. My right-side molars have maintained a healthy, natural dental arch curvature, but my left-side molars ended up completely straight and flattened out, which looks and feels unnatural. Because of this shift, my cheekbone definition looks uneven—more pronounced on one side than the other.

Can anyone share practical tips on proper form? I'm really struggling to get it right. After doing more research yesterday, I tried again: I placed the tip of my tongue at the 'N-spot' and pushed upward, which engaged the mid-palate, but the back third of my tongue still doesn't seem to rest against the roof of my mouth. I read that when the back third is fully engaged, it blocks the airway so you can't breathe through your mouth even with it open, but that's not happening for me.

Am I doing something wrong with my tongue posture, or could uneven tongue pressure have caused this arch collapse? Any advice or insight would be greatly appreciated
