yes but it will give you a better profile because you activate all those muscles in the mouth and neck area to force the tongue onto the top of the mouth. thats hardly anything revolutionary. its like saying "look when i contract my abs as hard as i can, it looks better than when i just let my belly bloat out".merlin said:The German Dream said:yeah...thats called muscle activation
Mewing incorrectly will give you unwanted muscle activation of the submental muscles, making your neck bloat outwards and potentially lower your hyoid bone and giving you a shitty neck area and profile. Mewing correctly will raise the hyoid bone, improving your profile.
