~ MIXEDPosture
Mouth Taping (Sleep)
Useful to enforce nasal breathing if you're a mouth breather — get sleep apnea ruled out first.
Also called: mouth tape · sleep tape · nasal breathing tape
Verdict — mixed
Real in part — the claim outruns what it actually does.
Evidence grade C
Mechanistic plausibility, small studies, or observational data. Suggestive, not established.
Mechanism
Forces nasal breathing during sleep, which supports resting oral posture (lips sealed, tongue on palate) and may reduce dry mouth and snoring.

The full read
Chronic mouth breathing is genuinely associated with altered facial development in children and worse oral health at any age. Taping is a blunt but sometimes effective habit-correction tool for adults. Safety first: if you can't comfortably nasal-breathe or have possible sleep apnea, taping can mask or worsen the problem — screen for apnea before trying it. Facial restructuring claims in adults are unsupported.
