Most people never think twice about where their tongue sits when it’s not busy talking or eating. But that resting position — what specialists call “tongue posture” — plays a much bigger role in your health than you’d expect. The correct resting posture is simple: tongue resting gently on the roof of the mouth just behind the front teeth, with the lips closed and teeth slightly apart. When the tongue rests low, forward, or against the teeth, it can quietly affect everything from your breathing to your posture to your sleep.
Below are seven signs that your tongue posture may be working against you — and what you can do about it.
You Breathe Through Your Mouth, Especially at Night
Correct tongue posture helps keep the airway open and encourages nasal breathing, which filters, warms, and humidifies the air you inhale. When the tongue rests low in the mouth, it’s harder to keep the lips sealed and the airway properly supported, so mouth breathing becomes the default — particularly during sleep. If you wake up with a dry mouth, notice you breathe through your mouth during the day, or have been told you sleep with your mouth open, low tongue posture may be a contributing factor.
Your Tongue Has a Scalloped or Wavy Edge
Take a look at the sides of your tongue in the mirror. Small ridges or indentations along the edges — known as tongue scalloping — are a common sign that the tongue doesn’t have enough room, or that it’s pressing against the teeth rather than resting on the palate. This is one of the clearest physical clues a myofunctional therapist looks for during an evaluation, as it often indicates a habitual low or forward tongue posture.
You Have Crowded Teeth or a Narrow, High-Arched Palate
Your tongue acts as a natural retainer, gently shaping the upper jaw as it grows. When it rests low instead of against the roof of the mouth, the palate doesn’t get that support and can develop a narrow or high-arched shape, leaving less room for teeth. This can lead to crowding, bite problems, or the need for orthodontic treatment. Even if braces fix the alignment, tongue posture that doesn’t change can contribute to relapse down the road.
You Struggle with Forward Head Posture, Neck Pain, or Headaches
Low tongue posture is frequently associated with forward head posture, in which the head sits ahead of the shoulders rather than stacked directly above them. Compensating for an unsupported airway or jaw position can pull the head and neck out of alignment, adding strain to the cervical spine. Over time, this pattern is associated with neck tension, tension headaches, and upper back discomfort — issues that may seem unrelated to the mouth but often trace back to it.
You Snore or Have Restless, Poor-Quality Sleep
When the tongue rests too far back or too low, it’s more likely to fall backward during sleep, narrowing the airway. This can contribute to snoring and, in more significant cases, may be a factor in sleep-disordered breathing or sleep apnea. If you or a partner have noticed snoring, gasping, restlessness, or you wake up feeling unrefreshed despite a full night’s sleep, it’s worth having your tongue posture and airway evaluated.
You Experience Jaw Pain, Clicking, or TMJ Discomfort
The tongue and jaw work as a team. When tongue posture is low, or there are tethered oral tissues (tongue-tie or lip-tie), the muscles around the jaw often compensate, which can alter jaw positioning and increase tension around the temporomandibular joint (TMJ). This may manifest as jaw clicking or popping, soreness when chewing, or a general feeling of tightness around the jaw and temples — especially first thing in the morning. Clenching and grinding of the teeth can contribute to further muscle tension and can also be related to airway distress during sleep.
You Notice Speech Difficulties or Frequent Bloating and Gas
Tongue posture doesn’t just affect how you breathe and sleep — it affects how you swallow and speak, too. An improper swallowing pattern, sometimes called a tongue thrust, can cause you to swallow excess air, leading to bloating or gas after meals. It can also make certain speech sounds (like “s,” “t,” “d,” or “l”) harder to articulate clearly. If you’ve dealt with a lisp, unclear speech, or unexplained digestive discomfort, it is worth a closer look.
What You Can Do About It
The good news is that tongue posture is trainable. Orofacial myofunctional therapy uses targeted exercises to retrain the muscles of the tongue, lips, and jaw, helping you build a healthier resting posture, breathing pattern, and swallow over time. Many people notice improvements in sleep quality, jaw comfort, and even posture as these patterns shift.
If any of these seven signs sound familiar, it may be worth a professional evaluation rather than guessing at the cause. A trained myofunctional therapist can assess your tongue posture, airway, and oral habits and build a personalized plan to address the root cause — not just the symptoms.
