Conclusion: Mouth tape (POP) is a useful device to treat patients with mild OSA and habitual OMB.
Pilot Study: Mouth tape for patients with mild obstructive sleep apnea and mouth breathing.
Subjects and methods: Patients with ≥5 events hourly but <15 hourly on the apnea-hypopnea index (AHI) were enrolled. All patients slept with their mouths closed by using the POP. Before treatment and during treatment, subjective outcomes were assessed using the Epworth Sleepiness Scale (ESS) and visual analog scale (VAS) of snoring. Objective outcomes were assessed using polysomnography and cephalometry.
Results: All patients slept with their mouths closed while using a POP. The ESS and VAS of snoring scores were 8.1 ± 1.5 and 7.5 ± 2.0 before the POP, respectively, in contrast to 5.2 ± 1.6 and 2.4 ± 1.4 while using a POP, respectively (P < .05). The median AHI score was significantly decreased by using a POP from 12.0 per hour before treatment to 7.8 per hour during treatment (P < .01). The snoring intensity and median snoring index were 49.1 ± 10.8 dB and 146.7 per hour before the POP, respectively, which decreased to 41.1 ± 7.8 dB and 40.0 per hour while using a POP, respectively (P < .01). Cephalometry revealed that the retropalatal space and retrolingual space were 7.4 ± 1.6 mm and 6.8 ± 2.5 mm before the POP, respectively, compared with 8.6 ± 1.2 mm and 10.2 ± 1.8 mm during treatment, respectively (P < .01).
Why Being a "Mouth-Breather" Is Bad For You w/James Nestor | Joe Rogan
Elimnate Brain Fog with Better Sleep on The School of Greatness
"A lot of people have sleep apnea or they are mouth-breathing during sleep. These days it's become popular to put tape on your mouth to keep your mouth shut and be a nasal breather....this leads to less sleep apnea, less mouth breathing, and less brain fog."

"Whenever possible you want to be nasal-breathing...don't be a mouth-breather."
Breathing on The School of Greatness
“Nasal-breathing alone can boost nitric oxide sixfold, which is one of the reasons we can absorb about 18 percent more oxygen than by just breathing through the mouth. Mouth taping cured their own snoring and breathing problems. Hundreds of other patients reported similar benefits.”
Mouth-Breathing is Killing you
“mouth-breathing is a cause of cavities, even more damaging than sugar consumption, bad diet, or poor hygiene. (This belief had been echoed by other dentists for a hundred years, and was endorsed by Catlin too.) Burhenne also found that mouth breathing was both a cause of and a contributor to snoring and sleep apnea. He recommended his patients tape their mouths shut at night. The health benefits of nose breathing are undeniable.”
While Hostage Tape is generally safe, these resources are meant for informational purposes only and should not replace professional medical advice from your physician. Do not use Hostage Tape if you have trouble breathing through your nose. Do not use if you are obese (BMI over 35), Do not use if you have very low blood pressure. Do not use if you have severe heart or breathing problems, or if you have a cold, sinus, or ear infection. Do not use if you have severely chapped lips or non-intact skin immediately around the mouth. Do Not use after consuming alcohol or sedatives. Seriously. Don't do it.
