Crooked Teeth Aren’t a Cosmetic Problem. They’re a Signal.
Most parents bring their child to an orthodontist for one reason: the teeth look crowded or crooked, and they want them straightened.
That’s a reasonable goal. But stopping there misses the most important question: why are the teeth crowded in the first place?
Answering that question, and treating the cause, not just the symptom, is what separates airway orthodontics from traditional orthodontics.
Teeth Don’t Crowd Themselves
Teeth are crowded because there isn’t enough room for them. The jaw didn’t develop to its full intended width and length, so teeth compete for space, rotating, tipping, and overlapping to fit somewhere.
This isn’t bad luck. It’s biology. And the jaw didn’t develop fully for reasons:
- Mouth breathing during critical growth years (the tongue rests on the floor of the mouth instead of the palate, removing the pressure that should widen the upper jaw)
- Prolonged pacifier or bottle use
- Thumb sucking
- Early loss of baby teeth without space maintenance
- Tongue tie that restricted proper tongue posture
- Genetics, but genetics loads the gun; environment pulls the trigger
The Jaw That Couldn’t Grow Properly
Here’s what traditional orthodontics often doesn’t address: a narrow jaw doesn’t just affect the teeth. It affects everything above and below it.
Above: The upper jaw forms the floor of the nasal cavity. A narrow upper jaw means a narrow nasal airway. Less space to breathe through the nose means more mouth breathing, which further narrows the jaw. The cycle reinforces itself.
Below: A lower jaw that didn’t develop enough affects tongue posture, can create a recessed appearance, and reduces the space the tongue has to sit during sleep. A tongue with nowhere to go can collapse toward the airway when muscles relax at night.
This is why so many children with crowded teeth also snore, mouth breathe, grind their teeth, and struggle with sleep and attention.
The teeth are the visible signal. The jaw and airway are the real story.
The Traditional Approach, and Why It Falls Short
Traditional orthodontics addresses the symptom: move the teeth to make them straighter. In many cases, this involves:
– Waiting until all permanent teeth come in (age 12-13)
– Extracting teeth to create space that the jaw never grew
– Braces or aligners to move remaining teeth into position
The result can look beautiful. But the jaw is still narrow. The airway is still compromised. The child still snores, still mouth breathes, still struggles with sleep. The root cause was never treated.
Worse: extracting teeth to create space in a jaw that should have been expanded may actually make the airway problem worse by reducing the arch width and further restricting tongue space.
What Airway Orthodontics Does Instead
Dr. Yoram Kohanzadeh, the first certified airway orthodontist in Southern California*, approaches crowded teeth as an airway problem, not just a cosmetic one. His evaluation looks at:
- Jaw width and length: is there enough space?
- Palate shape: is it high and narrow (a sign of mouth breathing and restricted development)?
- Tongue posture and tie: is the tongue able to sit where it should?
- Breathing pattern: nasal or oral?
- Sleep quality: snoring, grinding, restless sleep?
Where expansion is appropriate, Dr. K uses our BioX™ Protocol (Bio Expansion), expanding the upper and lower jaws together to encourage the jaw to grow the way it was always meant to. BioX is our own protocol, built on published expansion research and refined through 20+ years of clinical experience with our patients. It is cemented to the teeth, so nothing is placed into the palate unless it’s truly necessary, and it works by guiding the body’s own biologic growth. No extractions. No aggressive forces. The jaw gets the space it needed; the teeth follow.
Early Treatment Changes Everything
The best time to address this is during the growth window, typically age 5 through early adolescence. During these years, the jaw responds readily to guided growth. Treatment is faster, easier, and more complete.
But adults aren’t out of options. BioX is available from age 5 on for anyone with natural teeth, and adults, including those with implants, are evaluated case by case. A complimentary consultation comes first.
Start With the Airway Screening
If your child has crowded or crooked teeth, the cosmetic question and the airway question are the same question. Answer both at once.
