The 4 Goals of Myofunctional Therapy: How Simple Muscle Habits Can Transform Your Child's Breathing, Sleep, and Smile
When you first hear the term "orofacial myofunctional therapy," it can sound like a huge mouthful. You might picture an intimidating, endless list of mouth exercises or worry that your child will have to spend hours in front of a mirror every single day.
The wonderful truth is that effective myofunctional therapy is streamlined, intuitive, and focused on real-life function rather than boring drills.
Instead of overwhelming your child with dozens of random exercises, our program centers around The Four Core Goals. These four foundational goals work together like pieces of a puzzle to rebuild healthy muscle habits, support natural facial growth, and protect your child's airway.
Here is a deep dive into the four goals of myofunctional therapy, why each one matters so much, and how to spot if your child is struggling to achieve them!
Why Is Nasal Breathing So Important for Children?
Goal 1: Exclusive Nasal Breathing (Day and Night)
The primary and most critical goal of myofunctional therapy is establishing continuous nasal breathing. Your child's body was designed to breathe through the nose 24 hours a day, 7 days a week.
When your child inhales through their nose, their nasal passages filter, warm, and humidify the incoming air before it reaches their delicate lungs. But nasal breathing does something even more incredible: it releases a compound called nitric oxide, which is produced inside your child's sinuses. Nitric oxide acts as a natural anti-inflammatory and increases the efficiency of oxygen exchange in the lungs by up to 18 percent.
Nasal breathing also communicates directly with your child's nervous system. While mouth breathing triggers a "fight or flight" stress response, gentle nasal breathing activates the "rest and digest" parasympathetic nervous system. This lowers your child's heart rate, encourages deeper diaphragmatic breathing, and promotes calm, restorative sleep.
Signs your child needs help with Goal 1:
Breathing through their mouth while reading, watching TV, or sleeping
Snoring, heavy breathing, or gasping during sleep
Waking up frequently with a dry mouth, sore throat, or chapped lips
Struggling with chronic nasal congestion or seasonal allergies
How Do I Get My Child to Keep Their Lips Closed at Rest?
Goal 2: Effortless Lip Seal at Rest
Have you ever noticed your child hanging out with their mouth slightly open or their lips floating apart? This is known as lip incompetence or open mouth resting posture.
Goal 2 aims to train your child's lips to rest together easily and comfortably without any conscious effort or facial strain.
A healthy lip seal acts as the front door to your child's oral cavity. When your child keeps their lips sealed, it prevents their oral tissues from drying out and signals their brain to maintain nasal breathing.
However, keeping the lips closed should feel natural, not forced. When children with weak lip tone try to close their mouth, you will often see them strain their chin muscles. This causes the chin to look dimpled or bunched up like an orange peel. In myofunctional therapy, we teach your child how to engage their lip muscles while relaxing their chin, jaw, and neck.
Signs your child needs help with Goal 2:
Resting habitually with their mouth open or teeth showing
A chin that dimples, strains, or bunches up when they force their lips together
Dry, peeling lips despite drinking plenty of water
A short, weak upper lip that appears tucked under
Where Is My Child's Tongue Supposed to Rest in Their Mouth?
Goal 3: High Resting Tongue Posture
Did you know that your child's tongue is meant to rest entirely against the roof of their mouth?
Many parents assume the tongue simply sits in the bottom of the jaw. In reality, proper resting tongue posture means the entire body of the tongue (the tip, middle, and back) is lightly suctioned flat against the upper palate. The tip of your child's tongue should rest on "The Spot," a tiny ridge located right behind their upper front teeth.
When your child's tongue rests flat against their palate, it acts as nature's original orthodontic retainer and jaw expander. The gentle, constant upward and outward pressure of the tongue encourages your child's upper jaw to grow wide and U-shaped, creating plenty of room for all their adult teeth to erupt straight.
Furthermore, when the tongue rests high in the palate, it creates a gentle suction seal that prevents it from flopping backward into your child's airway while they sleep.
Signs your child needs help with Goal 3:
The tongue rests low on the floor of the mouth or presses against the front teeth
A narrow, high-arched upper palate or crowded, overlapping front teeth
Scalloped or wavy indentations along the sides of your child's tongue
An underlying tongue-tie that physically prevents the tongue from reaching the palate
What Is a Tongue Thrust Swallow and How Does It Affect My Child?
Goal 4: Correct Swallowing and Chewing Mechanics
Humans swallow roughly 1,000 to 2,000 times every day. In a healthy, mature swallow, your child's tongue creates a smooth wave against the palate to push food and liquids backward down the throat, without any help from their lips or cheek muscles.
When a child has low tongue posture or weak oral tone, they develop a tongue thrust swallow. Instead of lifting upward, your child's tongue pushes forward or sideways against their teeth to force a swallow.
To pull food down, your child has to compensate by tightly pursing their lips, squeezing their cheeks, or grimacing. Over time, thousands of daily tongue thrusts press against your child's teeth, leading to front teeth pushing outward, open bites, or orthodontic relapse.
Improper swallowing mechanics affect digestion and ear health too! A correct palatal swallow acts as a functional pump that helps drain your child's Eustachian tubes in their ear canals. When a child has a tongue thrust or low tongue posture, those tubes cannot drain properly, leading to fluid backup and chronic ear infections. Tongue thrusting also causes your child to swallow large amounts of air while eating, resulting in stomach bloating, gas, and acid reflux.
Signs your child needs help with Goal 4:
The chin, lips, or cheek muscles tighten dramatically every time your child swallows liquids or food
Loud, messy, or fast eating, or frequent food pocketing in the cheeks
A history of frequent ear infections, ear tubes, or stomach gas and bloating after meals
Speech articulation challenges, such as a frontal or lateral lisp on S, Z, CH, or J sounds
How Does Achieving These 4 Goals Help Your Child Grow?
When all four goals come together, your child's entire body benefits!
By restoring natural muscle function, myofunctional therapy supports healthy facial development, opens up your child's airway, and restores deep, quiet sleep. Parents often notice that once their child masters these four goals, they have better daytime focus, fewer mood swings, more energy, and a happier, healthier smile.
Our program is structured to make reaching these goals simple, enjoyable, and stress-free for busy families. Your child practices active, mirror-focused exercises for just 5 minutes, twice a day. We meet biweekly to review their form, track their progress, and ensure every new muscle pattern becomes second nature.
