It is just too common to hear a client say, “I wish my health care provider looked inside my mouth before prescribing medications, appliances, or surgery”, because the reality is, even after they try the “doctor's orders”, they still suffer with sleep, mood, and oral health issues despite the recommended approach that more prescribers offer. That is why I need to share the reality of the commonly overlooked symptoms and strategies with you today.
Mouth breathing: Causes, symptoms, and how to fix it naturally
Mouth breathing is far more common than most people realize. Many adults and children breathe through their mouths during the day or while sleeping without ever being aware of it. Over time, this pattern can quietly influence sleep quality, facial growth, oral health, and overall well-being. Because it often develops gradually, mouth breathing is easy to overlook.
Breathing through the mouth is not usually a conscious choice. It is often the result of airway challenges, muscle habits, or compensations the body learned early on. The encouraging part is that learned patterns can be relearned. With the right support, healthier breathing is possible at any age.
What is mouth breathing?
Mouth breathing occurs when air is taken in primarily through the mouth instead of the nose. It can happen while awake, during sleep, or both. In certain situations, such as a cold, sinus infection, or temporary congestion, mouth breathing is a normal short-term adaptation. It becomes problematic when it turns into the body’s default breathing pattern.
The nose is designed specifically for breathing. It filters airborne particles, humidifies and warms the air, and regulates airflow before it reaches the lungs. When breathing bypasses the nose, these protective functions are lost. Over time, habitual mouth breathing can affect how your blood regulates oxygen and carbon dioxide, stress hormones, and eventually how the muscles of the face, tongue, and airway function, leading to dysregulated sleep. And we all know what it’s like to get a poor night’s sleep!
Signs and symptoms of mouth breathing
Mouth breathing does not always look dramatic. Many of the signs are subtle and tend to blend into daily life, which is why they are often missed.
Mouth breathing in adults
Adults who mouth breathe may notice:
Dry mouth or sore throat upon waking
Snoring or disrupted sleep
Feeling unrefreshed despite adequate sleep duration
Jaw tension, clenching, or morning headaches
Daytime fatigue or brain fog
Difficulty concentrating or feeling chronically “run-down.”
Increased anxiety or a feeling of shallow breathing
Poor oral health despite good hygiene practices
Because these symptoms develop gradually, they are often attributed to stress, anxiety, depression, or aging, rather than breathing patterns. Sadly, people then seek pharmaceutical remedies that do not address the root cause of the symptoms.
Mouth breathing in children
In children, mouth breathing may present as:
Sleeping with the mouth open
Snoring or noisy breathing during sleep
Dark circles under the eyes
Frequent chapped lips or dry mouth
Crowded teeth or orthodontic concerns
Behavioral, attention, or learning challenges
Bedwetting past 5-6 years old
Early identification is especially important in children, as breathing patterns can influence sinus, facial, and cranial growth and development. In addition to this, since sleep cycles are affected by poor oxygenation or micro-arousals, their natural developmental cycles become impaired as limited growth hormones are being released during sleep.
What causes mouth breathing?
Mouth breathing usually develops from a combination of factors rather than a single cause. Some are structural, while others are functional or habitual.
Common contributors include:
Chronic nasal congestion from allergies or recurrent illness
Enlarged tonsils or adenoids
Deviated septum or narrow nasal passages
Low tongue posture or reduced oral muscle tone
Prolonged pacifier use or thumb sucking in early childhood
Poor posture or chronic stress affecting breathing patterns
Even when the original obstruction resolves, the nervous system may continue to default to mouth breathing. In these cases, the airway is technically open, but the habit remains.
Mouth breathing vs. nose breathing: Why it matters
Nasal breathing supports the body in ways that go beyond simply moving air in and out. As air passes through the nose, it is filtered and humidified, protecting the lungs and airway tissues. The nasal passages also produce nitric oxide, a molecule that helps improve oxygen delivery and circulation throughout the body.
Nose breathing encourages the tongue to rest against the roof of the mouth, where it helps support the upper jaw and maintain an open airway. This resting posture promotes stability in the jaw and neck and contributes to more efficient breathing during sleep.
Mouth breathing, by contrast, often leads to a low tongue posture and reduced muscle tone. Over time, this can increase airway collapse during sleep, contribute to snoring, and disrupt restorative sleep cycles.
Is mouth breathing bad for you?
Occasional mouth breathing is not inherently harmful. Persistent mouth breathing, however, may place extra strain on the body over time.
Potential effects include:
Poor sleep quality and increased snoring
Sleep apnea and chronic disease
Dry mouth and a higher risk of cavities or gum disease
Facial growth changes in children
Jaw tension or discomfort, TMJ dysfunction/pain
Reduced daytime energy and focus
Anxiety and depression
Relationship challenges and feelings of lost connection/intimacy
These changes tend to occur gradually, which is why mouth breathing often goes unrecognized for years.
Mouth breathing in children vs. adults
In children, mouth breathing can influence how the face, jaws, and airway develop. Early intervention can support healthier growth patterns and may reduce the need for more complex treatment later on.
Adults, however, are not beyond change. The muscles involved in breathing, posture, and oral function remain adaptable throughout life. With guided retraining, adults can improve nasal breathing, sleep quality, and overall comfort.
How to stop mouth breathing
Addressing mouth breathing starts with understanding what is driving it. In some cases, medical or dental evaluation is necessary to rule out structural concerns that limit nasal airflow.
Medical and structural support
This may include:
Evaluation by an ENT specialist
Management of allergies or chronic nasal congestion
Dental or orthodontic assessment when bite or jaw position is involved
Collaboration with chiropractors, cranial sacral therapists, or osteopaths
Functional and behavioral support
When mouth breathing is habitual, changing the pattern requires retraining the muscles and nervous system. This is termed myofunctional therapy and involves:
Establishing consistent nasal breathing
Improving tongue posture and lip seal
Improving facial muscle, coordination, and endurance
Addressing posture and breathing mechanics
Health/wellness coaching may be an additional benefit offered by some therapists
How myofunctional therapy helps mouth breathing
Myofunctional therapy focuses on the muscles of the mouth, face, and tongue that play a role in breathing, swallowing, and airway stability. Rather than addressing symptoms alone, it works to change the underlying functional habits that contribute to mouth breathing.
Through guided exercises and education, individuals learn how to establish nasal breathing, proper tongue posture, a relaxed lip seal, and ideal swallowing patterns. This approach is gentle, non-invasive, and tailored to each person’s needs.
Myofunctional therapy can support children during growth and development, as well as adults dealing with snoring, orthodontic relapse, jaw tension, or ongoing sleep concerns.
When to seek professional help
Mouth breathing that persists despite clear nasal passages, especially when accompanied by snoring, fatigue, dental concerns, or sleep disruption, is worth evaluating. A collaborative approach may involve medical, dental, and myofunctional professionals working together.
Early guidance can help clarify what is contributing to the pattern and prevent more complex issues from developing over time.
Final thoughts
Mouth breathing is common, often overlooked, and frequently reversible. Awareness is an important first step. With proper evaluation and support, many people are able to retrain their breathing patterns and experience meaningful improvements in sleep quality, comfort, and overall health.
If mouth breathing feels familiar, whether for you or your child, working with a trained myofunctional therapist can provide clarity, structure, and a sustainable path forward. Here are some quick links to help you resolve your challenges.
