airway orthodontics

Straight teeth are great. Breathing well is even better. Dr. Blackburn and Dr. Williams check both, because a narrow upper jaw can crowd the teeth and the nose at the same time.

Here’s the short version. The roof of your mouth is also the floor of your nose. When the upper jaw is narrow, there’s less room for the tongue and less room for air to get through the nose. A palatal expander slowly widens the upper jaw, and the nasal passage widens right along with it.

We place expanders in our office all the time. A few things you should know:

  • In kids, the two halves of the upper jaw haven’t fused yet, so a regular expander works beautifully. It feels like pressure, not pain, and kids get used to it fast. Ages 7 to 12 is usually the sweet spot.
  • Teens and adults can be expanded too. Once the jaw is done growing we use a bone-anchored expander (you may see it called MARPE). Small temporary anchors in the roof of the mouth let it widen the jaw itself, not just tip the teeth, and often without jaw surgery. Not every adult is a candidate, and we’ll tell you if you are.
  • We take a 3D x-ray so we can actually see the jaw, the nasal passages and the airway behind the tongue. No guessing.
  • We’re orthodontists, not sleep doctors. If we see signs of a breathing or sleep problem, we team up with your pediatrician, an ENT or a sleep physician. Only a physician can diagnose sleep apnea, and sometimes the real fix is tonsils, adenoids or allergies.
  • Not everyone needs an expander. We’ll tell you straight up if you or your kid does or doesn’t.

signs to watch for

mouth breathing

Breathing through the mouth during the day or while asleep.

snoring or restless sleep

Snoring, tossing and turning, or waking up tired after a full night in bed.

narrow palate or crossbite

A narrow upper jaw, a crossbite, or teeth that are badly crowded.

None of these means something is wrong for sure. They do mean it’s worth a look. Call us at 281-769-3095 or schedule a visit and we’ll check.

what the research says

a wider jaw makes room to breathe through the nose

A review of the long-term studies in growing kids found moderate evidence that expansion improves the conditions for nasal breathing: the nasal cavity gets wider, air meets less resistance, and more air flows through. The results held for at least 11 months.

kids with a narrow palate and sleep apnea slept better

A review of 17 studies followed 314 children who had a narrow palate and sleep apnea. After expansion, pauses in breathing during sleep dropped by about 70 percent on average, and the lowest overnight oxygen level rose from 87 to 96 percent. About 1 in 4 of the kids who could be checked had a fully normal sleep study afterward, which is why a sleep doctor stays in the loop.

it can help adults too

A 2022 trial followed 32 adults who had a narrow upper jaw and sleep apnea. Six months later, the group treated with a bone-anchored expander had about 65 percent fewer pauses in breathing, plus less snoring and less daytime sleepiness. It’s a small study, so we call it promising, not proven.

the orthodontist screens, the physician diagnoses

The American Association of Orthodontists’ paper on sleep apnea says orthodontists should watch for the warning signs and refer, and that the diagnosis has to come from a physician. That’s exactly how we do it.
