As an integrative and biological dental practice, Dr. Noha Oushy and Santa Teresa Smiles’ focus extends beyond teeth. We look at the mouth as a gateway to whole-body health—and that includes how you breathe. While often overlooked, the way you breathe can drastically affect your oral and systemic health. One of the most critical distinctions? Mouth breathing vs. nasal breathing.
What’s the Difference between Mouth and Nasal Breathing?
At first glance, breathing through the nose or mouth might seem like a small detail. But it’s anything but. Your nose is designed for breathing—it filters, humidifies, and warms the air before it enters your lungs. Your mouth? It’s designed for eating and speaking, not breathing 24/7.
Hidden Dangers of Mouth Breathing
Chronic mouth breathing can lead to serious complications—especially in children whose facial structures are still developing. Here’s what it can cause:
- Dry mouth and increased cavities Saliva is your mouth’s natural defense against bacteria. Mouth breathing dries it out, promoting plaque and tooth decay.
- Gum disease Lack of saliva means more bacterial buildup, leading to inflammation and gum issues.
- Facial development problems In children, mouth breathing can alter jaw growth, leading to narrow arches, crowded teeth, and even the need for orthodontics.
- Sleep-disordered breathing Mouth breathing at night is linked to snoring and sleep apnea, which can affect concentration, mood, and heart health.
- Poor oxygenation Nasal breathing promotes nitric oxide production, which enhances oxygen delivery. Mouth breathing bypasses this system.
Health Benefits of Nasal Breathing
Switching to nasal breathing is one of the simplest, most profound ways to improve your health. Here are the key nasal breathing benefits:
- Improved oxygen uptake Nitric oxide produced in the nasal passages helps your lungs absorb more oxygen efficiently. Better oral health Nasal breathing helps maintain moisture and pH in the mouth, reducing the risk of cavities and gum disease.
- Facial development In children, nasal breathing supports proper jaw growth and tooth alignment.
- Higher quality sleep Nasal breathing reduces the risk of snoring and promotes deep, restorative sleep.
- Stronger immune system Nasal hairs and mucus trap pathogens, protecting your body from illness.
Can You Change Your Breathing Habits?
Changing how you breathe isn’t always easy—but it’s possible, and well worth the effort. Here’s how to start retraining your body:
- Get evaluated A biological dentist or airway-focused provider can assess your breathing patterns, jaw development, and tongue posture.Santa Teresa Smiles and Dr. Noha Oushy is an affiliate of The Breathe Institute and certified airway practitioner.
- Practice proper tongue posture Your tongue should rest on the roof of your mouth, not the floor. This encourages nasal breathing and proper jaw alignment.
- Try mouth taping at night Gentle mouth tape (like MyoTape or micropore tape) can help you keep your lips closed during sleep.
- Treat nasal blockages Allergies, deviated septums, and sinus issues can make nasal breathing difficult. Consider ENT support or functional medicine approaches.
- Use breathing exercises Techniques like the Buteyko Method can retrain your breathing and improve CO₂ tolerance, which supports easier nasal breathing.
- Myofunctional therapy A myofunctional therapist can help correct tongue posture, lip seal, and breathing habits. Susana Sexauer is a certified myofunctional therapist and practices in our office one day a week!
