In the world of holistic health, we often hear about the importance of spinal posture—sitting up straight to avoid back pain. But there is another type of posture that is arguably even more critical to your systemic health, yet rarely discussed: oral posture. Specifically, where your tongue rests when you aren’t speaking or eating.
It might seem trivial, but the position of your tongue acts as the scaffolding for your entire facial structure. It dictates how your jaw develops, how well you sleep, and most importantly, how effectively you breathe. When this posture is incorrect, it triggers a domino effect of issues ranging from narrow dental arches and crowded teeth to chronic mouth breathing and obstructive sleep apnea (OSA).
At Honest Family Dental in Austin, TX, we look beyond the teeth to understand the root causes of these issues. By understanding the connection between your tongue and your airway, you can take the first step toward better sleep, improved energy, and lifelong respiratory health.
Key Takeaways
- Natural Scaffolding: Your tongue acts as a natural palate expander. Correct posture supports the upper jaw’s width and forward growth.
- The “Mewing” Connection: Resting the tongue on the roof of the mouth (often called mewing) is essential for maintaining an open airway.
- Systemic Impact: Poor tongue posture is a leading cause of mouth breathing, which is linked to sleep apnea, fatigue, and developmental issues in children.
- Non-Invasive Solutions: Myofunctional therapy can retrain oral muscles, often eliminating the need for invasive surgeries or lifelong CPAP use.
What is the relationship between tongue posture and airway health?
Proper tongue posture involves the entire tongue resting against the roof of the mouth (the palate), which provides essential structural support for the maxilla (upper jaw) and ensures a patent oropharyngeal airway. Conversely, low tongue posture leads to narrow dental arches, vertical facial growth, and airway collapse, significantly contributing to sleep-disordered breathing and chronic fatigue.
When we talk about the relationship between the tongue and the airway, we are talking about physics and anatomy. The tongue is a powerful muscle. When it rests correctly—suctioned flat against the palate with the tip just behind the front teeth—it exerts continuous, gentle pressure on the maxilla. This pressure does two things:
- It counteracts the inward pressure of the cheeks (buccinator mechanism), preventing the dental arch from collapsing.
- It encourages the maxilla to grow forward and wide, which naturally increases the volume of the nasal cavity and the posterior airway space.
However, if the tongue rests on the floor of the mouth, the upper jaw lacks this internal support. Over time, the palate narrows (becoming a “high-vaulted palate”), and the nasal floor rises. This reduces the space available for airflow, forcing the body to switch to mouth breathing—a less efficient and often detrimental way to oxygenate the body.
The Anatomy of Airway Health: A Deep Dive
To understand why “just close your mouth” isn’t always enough, we need to look at the biomechanics of the upper airway.
The Genioglossus Muscle and Airway Patency
The genioglossus is the largest muscle of the tongue and the primary dilator of the upper airway. Its function is critical during sleep. When you fall asleep, muscle tone naturally relaxes. If the genioglossus is weak or accustomed to a low resting position, it is more likely to collapse backward against the pharyngeal wall, obstructing the airway. This is the mechanical basis for many cases of Obstructive Sleep Apnea (OSA).
Palatal Expansion and Nasal Resistance
The roof of your mouth is also the floor of your nose. A wide palate equals a wide nasal floor. When the tongue fails to expand the palate, the nasal cavity remains narrow, increasing “nasal resistance.” High nasal resistance makes nose breathing physically difficult, creating a vicious cycle: you can’t breathe through your nose, so you mouth breathe; because you mouth breathe, your tongue drops; because your tongue drops, your palate narrows further.
How does myofunctional therapy improve breathing?
Myofunctional therapy utilizes targeted neuromuscular re-education exercises to retrain the orofacial muscles and tongue to rest in their optimal position, known as the “spot.” By strengthening the airway dilator muscles (specifically the genioglossus) and habituating nasal breathing, this therapy addresses the functional root cause of mouth breathing and obstructive sleep apnea without invasive intervention.
Think of myofunctional therapy as physical therapy for your mouth. It isn’t just about moving the tongue; it is about changing the brain’s connection to the muscles of the face and throat.
- Restoring Nasal Breathing: The primary goal is to establish a lip seal and promote exclusive nasal breathing. Nasal breathing filters, warms, and humidifies air, while also producing nitric oxide—a vasodilator that improves oxygen absorption in the lungs.
- Correcting Swallowing Patterns: Many people with poor tongue posture utilize a “tongue thrust” or “reverse swallow,” pushing the tongue against the teeth rather than up against the palate. Therapy corrects this, protecting the teeth from shifting.
- Stabilizing the Jaw: By toning the masseter and temporalis muscles alongside the tongue, therapy helps stabilize the jaw during sleep, reducing the likelihood of the mandible falling back and closing the airway.
The Honest Family Dental Approach
At Honest Family Dental, we believe that the “truth is in the tooth”—but the solution often involves the whole body. We don’t just patch up cavities; we look for the why.
Dr. Ameet Trivedi, often called the “Tesla of Dentists,” integrates biomimetic dentistry with airway-centric treatments. Our approach to airway health is rooted in the Vivos System and comprehensive Myofunctional Therapy.
We recognize that malocclusion (bad bite) and TMJ pain are often symptoms of an underlying airway problem. By using non-surgical appliances like the DNA and mRNA systems from Vivos, we can essentially remodel the airway. These devices apply pneumopedics (airway remodeling) to gently expand the palate and advance the jaw. When combined with myofunctional therapy to train the soft tissues, we achieve results that are not just cosmetic, but curative.
We act as “architects” of the mouth, ensuring that the structure (the jaw and palate) is sound so that the function (breathing and sleeping) can be optimal.
Identifying Red Flags: Is Your Airway Compromised?
You might not realize that your dental health is connected to your sleep quality. Here are common “red flags” that indicate a tongue posture or airway issue:
- Chronic Mouth Breathing: If your lips are parted at rest (watching TV, reading), your tongue is likely low.
- Scalloped Tongue: Look in the mirror. Does the side of your tongue look wavy or “scalloped”? This indicates your tongue is too large for your dental arch and is pressing against your teeth.
- Teeth Grinding (Bruxism): Grinding is often the body’s attempt to push the jaw forward to open a collapsing airway during sleep.
- Venous Pooling: Dark circles under the eyes can be a sign of poor oxygenation and nasal congestion caused by airway restriction.
- Forward Head Posture: To keep the airway open, many people subconsciously crane their neck forward, leading to neck and shoulder tension.
Frequently Asked Questions
Q: Can adults fix their tongue posture?
A: Yes, adults can correct their tongue posture through consistent practice and myofunctional therapy. While the skeletal structures of children are more malleable, adult bone is capable of remodeling (neuroplasticity and bone remodeling). Adults can successfully retrain their resting posture, improve nasal breathing, and in many cases, achieve some degree of palatal expansion through appliance therapy like Vivos.
Q: Does mewing actually work?
A: “Mewing” is the internet term for proper oral posture, and the fundamental concept is scientifically sound. The practice of resting the tongue against the palate is the biological norm. While internet trends often exaggerate the speed of cosmetic changes (like a sharper jawline), the functional benefits—improved breathing and airway support—are well-documented in dental sleep medicine.
Q: What is the connection between tongue tie and sleep apnea?
A: A tongue tie (ankyloglossia) physically tethers the tongue to the floor of the mouth, making it mechanically impossible to rest on the palate. This forces a low tongue posture, which leads to mouth breathing and a higher risk of developing sleep apnea. Releasing a tongue tie (frenuloplasty) is often a necessary step in restoring airway health.
Final Thoughts on Tongue Posture
Your breath is your life source, and your tongue is the gatekeeper. Ignoring oral posture doesn’t just lead to crooked teeth; it compromises your ability to breathe freely and sleep deeply.
