I have (or had, maybe more now, I should have it measured again) 40 mm back molar and 34 mm canine distance, I can place my tongue now relatively ok. Question is, will tongue posture and heavy chewing on mastic gum expand my palate? I need another 6-8 mm it seems. I did measurements and it looks like thats the all round gains I need, about the length of a molar for full recovery. Its about the distance my mandible needs for a comfortable bite ... I cant imagine the maxilla moving that far forwards tho. It needs to move 5 mm forward.
Can this be done just mewing, posture and chewing in a 5 year period?
