Children & Teens · Ages 8–17
Crowded teeth are a symptom — not the cause.
By age 8, the consequences of an underdeveloped airway are becoming visible: crowded teeth, a narrow face, mouth breathing, difficulty concentrating. The ideal window was before age six — but meaningful improvement is very much possible through the teenage years. Dr. Haller treats the reason the crowding happened and expands the arch to make room, rather than extracting teeth to fit a small jaw.
What parents, teachers, and coaches notice
- Crowded, crooked, or overlapping teeth
- Narrow dental arch or high, narrow palate
- Mouth breathing — lips apart at rest, chapped lips
- Snoring or restless sleep
- Difficulty focusing, poor academic performance
- ADHD diagnosis — often with unaddressed airway component
- TMJ pain, jaw clicking, headaches
- Forward head posture, neck and shoulder tension
- Anxiety or depression — may have airway / sleep component
- Long, narrow face developing over time
- Frequent colds, ear infections, sinus problems
Why extractions are often the wrong answer
Traditional orthodontics frequently recommends extracting permanent teeth to make room for crowded teeth. But crowding is a symptom of a jaw that didn’t develop to its full potential — usually because of mouth breathing and low tongue posture. Extracting teeth makes the existing small arch even smaller, reducing airway space further. Dr. Haller expands the arch instead — making room for all the teeth while simultaneously opening the airway.
What is sometimes missed
Posterior tongue ties are frequently undetected into the teenage years — especially if breastfeeding wasn’t difficult. TMJ pain, chronic headaches, forward head posture, and fatigue in older children and teens are commonly attributed to stress or posture habits. In many cases the tongue tie is the origin — and releasing it, combined with myofunctional therapy and arch expansion, addresses the root.
What we can do — ages 8 through 17
Treatment is tailored to each child’s age, anatomy, and stage of development. Dr. Haller often combines approaches — using different appliances sequentially or together for the best result.
- Tongue tie evaluation and release — a step Dr. Haller frequently takes early in treatment if a restriction is identified
- Traditional orthodontic expanders — both fixed (cemented to the teeth) and removable versions, used to widen the palate and open the nasal airway
- ALF (Advanced Light Force) appliance — a gentle wire-based appliance that works with the cranial system to develop the arch and improve breathing; Dr. Haller is clinically trained in ALF therapy
- Functional appliances — continue to guide jaw development using natural muscle forces
- Clear aligners — used in finishing stages to refine tooth alignment once the arch has been adequately expanded
- Myo Munchee — builds jaw muscle strength and supports nasal breathing
- Laser tonsil decontamination — if enlarged tonsils are contributing
- Nasal Release Therapy (NRT) — opens nasal passages that may have been restricted for years
- Myofunctional therapy — retrains tongue posture and swallow pattern before and after release
- Coordination with pediatrician, ENT, speech therapist, and orthodontist
“A narrow palate is a narrow airway. When I expand the arch in a child, I’m not just straightening teeth — I’m opening the nasal passages, improving nasal breathing, and changing the entire developmental trajectory.”
