Mouth Taping for Snoring Reduction

A preliminary clinical study of 20 mild OSA patients who were confirmed mouth-breathers found that mouth taping reduced median AHI by approximately 47% and snoring index by 47%, with the greatest improvements seen in those with higher baseline severity.

A 2025 systematic review covering 213 patients across 10 studies found only two studies showed statistically significant OSA improvements; others showed no difference, and the review highlighted potential asphyxiation risk in people with nasal obstruction.

A 2024 randomized controlled trial found that a multi-component therapy including mouth taping reduced primary snoring in 58% of participants, but a mandibular advancement device alone outperformed it at 91% response rate.

A 2025 scoping review noted that while some research suggests mouth taping may help with OSA and snoring, the overall literature is markedly heterogeneous with little consensus, and most TikTok-driven claims have not been scientifically evaluated.

A 2025 Dutch clinical commentary concluded that nasal breathing varies naturally and physiologically for most people, and that mouth taping is not necessary to change normal breathing patterns.
