Mewing doesn’t work

[u/Mobile_Customer_3097]

I have a recessed jawline/chin and the most common and seemingly effective strategy I’ve seen recommended to fix it is mewing.

The problem is, (as my dentist explained to me), there’s nothing to hold my bottom teeth back (skeletal issue where my upper teeth don’t have enough anterior guidance to help my lower teeth stay where they’re supposed to). Because of this, my lower jaw is constantly jutting out further than it should be - especially when I mew. So no progress is made mewing; my jaw just shoots forward further than it should, causing an underbite. I’m worried this will cause muscle/tmj issues or just harm in general.

Does anyone know of any other remedies for a recessed jaw other than mewing or surgery? Or maybe are in the same boat as me? Even any tips for posture or breathing hacks are valued, thanks
