What is the verified physiological evidence for palatal tongue posture?
Resting palatal tongue posture ('mewing') is classified as Plausible for functional airway maintenance, but Anecdotal for radical adult maxillary expansion. Clinical literature demonstrates it stabilizes submental soft-tissue tone and encourages mandatory nasal breathing, reducing mouth-breathing related facial elongation during growth phases. However, claims of changing adult mandibular angle through tongue force alone lack controlled peer-reviewed validation.

Maintaining light palatal contact with the entirety of the tongue at rest to encourage nasal breathing and prevent mouth breathing.
