Call me weird, but oral health has always fascinated me. And it’s more than just brushing your teeth twice a day and flossing. Mouth taping is a newer trend in the natural oral care world, but it’s about so much more than that. This one simple habit can help your overall health improve, sometimes dramatically.
So how does putting a tiny strip of tape over your mouth before bed make that much of a difference? The idea may sound strange, even a little uncomfortable. But after digging into the science and trying it myself, I found something so simple can still have a huge ripple effect on sleep, energy, and even long-term health.
While mouth taping may seem like just another wellness trend, it actually addresses an issue many of us don’t even know we have. Mouth breathing is increasingly common and can cause a cascade of problems.
Why Mouth Breathing at Night Matters More Than You Think
How we breathe is foundational to our health. But for about 50% of the population, mouth breathing (especially during sleep) has become the norm. This seemingly harmless habit is linked to a surprising list of health concerns, both in kids and adults.
1. Dry Mouth, Cavities, and Bad Breath
When we breathe through our mouth this dries out saliva, which plays a key role in protecting teeth and gums. Saliva keeps the mouth pH balanced, remineralizes teeth, and helps prevent cavities. When saliva production drops at night due to mouth breathing, our risk of tooth decay, gum irritation, and bad breath jumps. You can read more about the importance of saliva here.
2. Facial Development, Jaw Alignment, and More
Especially in children, proper tongue posture is essential for healthy facial development. When the tongue doesn’t rest on the roof of the mouth (like during nasal breathing), it can lead to narrower palates, crooked teeth, and underdeveloped jaws. These changes can also impact hearing, speech development, and even vision. All of these systems are connected during the developing years.
3. Tonsil Inflammation
Your nose is nature’s air filter and warms, moisturizes, and cleans the air you breathe. When we bypass the nose and breathe through the mouth, the tonsils take on that role. Over time, this can irritate and inflame the tonsils, especially in kids. The result? Enlarged tonsils, tonsillitis, mouth breathing cycles, and even sleep-disordered breathing.
4. Obstructed Airways
When we’re mouth breathing and the tongue isn’t where it should be, we’re not breathing deeply and clearly. This oxygen deprivation leads to a whole host of problems, from daytime sleepiness to trouble concentrating and ADHD symptoms.
While there are obvious downsides to mouth breathing (especially at night), mouth taping can be an easy solution.
What Is Mouth Taping?
Mouth taping is a gentle practice that uses a small piece of skin-safe tape to keep the lips closed. This helps promote nasal breathing and encourages the lips to stay closed at night. It can also help nudge the tongue into the proper posture.
If you’re someone who wakes up with a dry mouth or snores often, this simple shift can make a world of difference. And even if you (or your partner!) don’t snore at night, you still may be mouth breathing without knowing it.
Benefits of Mouth Taping (Backed by Research)
Once I got past the initial awkwardness, mouth taping’s benefits became pretty noticeable. Here are a few reasons why this practice is gaining traction in holistic (and even mainstream) health circles:
1. Less Snoring and Dry Mouth
Mouth taping naturally reduces snoring for many people by stabilizing the airway through nasal breathing. With less vibration of soft tissues in the throat, the sound (and health risks) of snoring often improve. Snoring isn’t just annoying, it points to some deeper health issues. You’ll also wake up with a moist mouth instead of that dry, cotton-mouth feeling.
2. Better Dental Health
Saliva is our body’s natural defense against cavities and gum disease. Nasal breathing helps preserve saliva through the night, reduce the risk of decay, and helps keep the oral microbiome in balance.
3. Improved Sleep and Energy
One of the most noticeable benefits is better quality sleep. When we breathe through our nose we’re getting more oxygen and our body is more likely to stay in that deep, restorative sleep. This is when our brain cleans house, so it’s vital for helping guard against neurodegenerative disorders, like Alzheimer’s. You might notice less waking up in the night, better focus during the day, and a general lift in mood and energy.
4. More Oxygen to the Brain (and Fewer Negative Brain Symptoms)
One fascinating connection is the link between mouth breathing and symptoms that mimic ADHD in children. Studies show low oxygen levels at night caused by sleep-disordered breathing can lead to poor concentration, hyperactivity, and behavioral issues during the day. Some children diagnosed with ADHD show significant improvement just from addressing their sleep and breathing patterns.
On the other end of the spectrum is disordered breathing’s link to brain disorders in adults. Those who mouth breathe at night or have disordered breathing are significantly more likely to develop Alzheimer’s disease.
Sleep Apnea, ADHD, and the Bigger Picture
The effects of poor breathing habits at night go beyond just dry mouth or fatigue. It’s estimated that over 1 billion adults worldwide have obstructive sleep apnea. In this condition the airway collapses during sleep and disrupts our oxygen supply. Many of these cases go undiagnosed for years or still remain undiagnosed.
Sleep apnea has been linked to a long list of health problems, including:
- High blood pressure
- Heart disease
- Stroke
- Type 2 diabetes
- Depression
And sleep apnea is just the extreme end of a spectrum. A lesser-known but very common issue is upper airway resistance syndrome (UARS). This is where the body works harder to breathe at night, often without full apneas, but still has poor oxygenation. One red flag for UARS? Teeth grinding.
When Mouth Taping Isn’t a Good Idea
Mouth taping can be powerful, but it’s not for everyone. There are a few situations where it should be avoided or approached with caution:
- Young children: Kids who aren’t old enough to remove the tape themselves should not use mouth tape. Babies and very young children have delicate airways that can easily become clogged so it’s important to keep their nasal airways open to encourage nasal breathing habits.
- Nasal congestion or anatomical blockages: If you can’t breathe easily through your nose while awake, you shouldn’t force it at night.
In these cases, it’s important to address the root causes of nasal blockage first. Some common culprits include:
- Mold exposure in the home
- Environmental allergens (why we have air filters in our home)
- Food sensitivities (especially dairy and gluten)
- A deviated septum or other anatomical issues
- Narrow palate or misaligned jaw
A great place to start is with an airway-focused ENT (ear, nose, and throat specialist) or a holistic dentist trained in functional breathing and jaw development. They can perform evaluations like 3D cone beam scans. They’ll assess the airway structure and help identify whether soft tissue or skeletal changes are needed. A myofunctional therapist is also a helpful route for mouth breathers to train the tongue to move correctly.
What to Do If You Can’t Breathe Through Your Nose
If mouth taping feels impossible because your nose is always blocked, you’re not alone. This is often a signal your daytime breathing habits need some attention too.
Here are some ways to help retrain your breath:
- Tongue posture: The tongue should rest on the roof of the mouth, not the bottom. This posture helps widen the palate and support nasal breathing.Myofunctional therapists are helpful for this.
- Deep breathing: Practices like yoga and breathwork teach you how to breathe more efficiently with the diaphragm.
- Nasal rinses: Saline rinses or a neti pot can help reduce inflammation and clear mucus from the nasal passages. This is great for allergies or during illness.
- Mouth and jaw training: Myofunctional therapy involves exercises that strengthen the muscles of the face, mouth, and airway to improve breathing and oral posture.
If physical changes are needed, like correcting a deviated septum or expanding a narrow jaw, there are options for both kids and adults. Treatment might include myofunctional orthodontics, expansion devices, or minor surgical corrections. While these interventions can take time, the long-term health benefits are well worth it. Here’s what my kids have done instead of braces.
How to Start Mouth Taping (and What to Use)
Mouth taping is one of those simple practices that most people can benefit from. Even if you don’t think you’re snoring, having apneas, or mouth breathing at night, you actually might. Something like an Oura ring can track your nighttime sleep and offer clues to how much rest (or not) you’re getting. If you’re really concerned, you can ask your doctor about a sleep study to monitor nighttime breathing.
An easy (and cheaper) way to get the benefits of nasal breathing at night though is to just start wearing mouth tape. There are lots of options now, but some of them have downsides. Some mouth tape can be difficult to remove, leave a sticky residue, or be uncomfortable to sleep in.
Wellnesse is my favorite brand for oral care products and they have a really great mouth tape. It’s made with bamboo silk so it’s comfortable and I like that it covers the entire lip area. If you’re subconsciously breathing around the tape at night, it’s not really helping. It’s also easy to remove for when it is time to take it off. They come in an eco-friendly container in individual tape strips, so there’s no fuss. You can learn more about Wellnesse mouth tape and try it here.
Final Thoughts on Mouth Taping’s Surprising Benefits
Mouth taping isn’t just about reducing snoring or waking up with fresh breath. It’s about reclaiming one of the body’s most important, overlooked functions, how we breathe. When we sleep, we spend about a third of our lives in a deeply restorative state. Making sure that time is optimized with proper oxygen flow, airway stability, and tongue posture can have far-reaching effects on everything from focus and mood to cardiovascular health.
So, if you’re waking up tired, grinding your teeth, or dealing with constant congestion, consider whether mouth breathing could be part of the picture. You might be surprised how much this small change can have major benefits.
