The Truth Behind the Viral TikTok Mouth Taping Trend

Can Mouth Taping Really Solve Snoring and Contour Jawlines?

A recent TikTok trend has sparked widespread curiosity and debate: mouth taping. Promoted as a solution for snoring, bad breath, teeth grinding, and even jawline definition, this trend has gained significant traction. But is it safe, and does it live up to the hype? Dr. Zac Turner, in an article published on News.com.au, delves into the science and potential risks behind this viral phenomenon.

Why Nasal Breathing Is Superior

Breathing through the nose is often compared to “upgrading to first class on a flight.” According to Dr. Zac, the nose acts as a “multi-tasking superhero,” filtering, warming, and humidifying air before it reaches the lungs. It also produces nitric oxide, a molecule that enhances oxygen uptake and has antimicrobial properties. In contrast, mouth breathing is likened to “flying economy on a budget airline,” skipping these benefits and potentially leading to dry mouth, bad breath, disrupted sleep, and higher infection risks.

Chronic mouth breathing during sleep is linked to snoring, sleep apnea, and even changes in facial structure over time. Research published in Sleep Medicine Reviews and the Journal of Clinical Sleep Medicine supports the importance of nasal breathing for improving oxygen exchange and reducing sleep disruptions.

The Concept Behind Mouth Taping

The mouth taping trend aims to encourage nasal breathing by physically preventing mouth breathing during sleep. Proponents claim it can help users wake up feeling refreshed and even improve jawline definition. However, Dr. Zac cautions that while the idea of promoting nasal breathing is sound, the method raises significant safety concerns.

The Potential Benefits and Risks

The Good

Encouraging nasal breathing is a scientifically supported goal. Studies suggest that nasal breathing improves oxygenation, reduces snoring, and may lead to better sleep quality. For individuals who already breathe through their noses, mouth taping could theoretically help maintain this habit.

The Bad

However, mouth taping poses risks, especially for those with nasal congestion, allergies, or structural issues like a deviated septum. “Imagine waking up in the middle of the night unable to breathe,” Dr. Zac warns. Additionally, some tapes may cause skin irritation, leading to rashes around the mouth.

As for the myth of swallowing bugs during sleep, Dr. Zac clarifies that it is entirely unfounded. “No self-respecting spider is crawling into a warm, snoring mouth,” he quips.

Safer Alternatives to Promote Nasal Breathing

For those intrigued by the benefits of nasal breathing but wary of mouth taping, Dr. Zac suggests several safer alternatives:

Clear Your Nose

Using tools like a neti pot for saline irrigation can help clear sinus blockages gently and effectively. Studies in Respiratory Medicine highlight the benefits of this method for improving nasal airflow.

Strengthen Airway Muscles

Myofunctional therapy, which involves exercises to strengthen the tongue and airway muscles, can support better breathing. Research in the European Respiratory Journal indicates its potential to reduce snoring and improve airway health.

Adjust Sleep Position

Sleeping on your side rather than your back can encourage nasal breathing. Proper pillow placement can also help align the body and improve airflow.

Practice Nasal Breathing

Dr. Zac recommends practicing nasal breathing during low-risk activities, such as driving or relaxing at home, to build comfort and confidence.

When to Avoid Mouth Taping

Dr. Zac advises against mouth taping for individuals with nasal congestion, sleep apnea, or anatomical issues like a deviated septum. “No amount of tape is going to fix it,” he states, recommending consultation with an ENT specialist for such cases. He also emphasizes that children and older adults, who may face unique challenges with mouth breathing, should focus on good nasal hygiene rather than experimental trends.

Should You Try It?

While mouth taping isn’t inherently dangerous, Dr. Zac notes that there is insufficient scientific evidence to support its purported benefits. “Most doctors wouldn’t recommend it, especially when there are other proven solutions out there,” he concludes. For those seeking to improve their breathing and sleep quality, safer and more established methods are available.

Ultimately, the goal is to promote healthy, natural nasal breathing—without resorting to TikTok’s latest trend.
