Key Takeaways

• Adult airway problems often trace back to childhood growth patterns, but adults can still benefit from a thoughtful, team‑based approach.
• Orthodontics can improve jaw position and tongue space, but it does not replace medical care for sleep apnea.
• Expect a collaborative process. We coordinate with sleep physicians and ENTs to align orthodontics with medical therapy.

Common Adult Airway Challenges

Adults often come to us after years of snoring, waking up unrefreshed, or relying on mouth breathing, sometimes alongside daytime sleepiness or trouble focusing. If you suspect you have obstructive sleep apnea (OSA), the starting point is a medical evaluation and, when appropriate, a sleep study. Learn more about screening and diagnosis from the American Academy of Sleep Medicine.

How Orthodontics Can Help, and Its Limits

In adults, orthodontics may help by straightening teeth and improving jaw alignment, which can create more stable tongue space and reduce mouth‑breathing habits. In some cases, expanding narrow arches with modern techniques or advancing the bite can support better airflow. That said, orthodontic treatment does not diagnose or treat medical sleep disorders and is not a standalone cure for OSA.

Adults with suspected or diagnosed OSA should follow guidance from their sleep physician. Depending on the severity of their OSA, treatment can include weight management, positional therapy, use of a CPAP machine, oral appliance therapy, surgery, or a combination of these. For patient‑friendly overviews, see the AASM’s pages on OSA treatment options and CPAP therapy.

For selected adults, especially those with narrow arches, crowding, or bite discrepancies, orthodontic care may complement medical therapy by improving your dental arch form and jaw function. At Miller Orthodontics, we’ll be clear about benefits, limits, and timelines of orthodontic care.

How We Work With Your Sleep Team

We collaborate with sleep physicians and ENTs to make sure orthodontic treatment supports, not competes with, medical care. If an oral appliance is recommended for mild to moderate OSA, we can help coordinate orthodontic alignment to optimize fit and comfort. If a CPAP machine is the best option, orthodontic treatment can still address bite concerns, crowding, or breathing habits that affect quality of life.

Is Adult Orthodontic Treatment Worth It?

Adults often ask if they’ve “missed the window” for orthodontic treatment. While growth guidance is most powerful in childhood, adults can still see meaningful improvements in comfort, function, and confidence. The right plan blends medical care with realistic orthodontic goals.

Next Steps

• If you suspect OSA, start by seeing your primary care doctor or a sleep physician for an evaluation.
• If you’re already under care for OSA, bring your sleep study and treatment plan to your first appointment. We’ll coordinate with your other providers, so that orthodontics supports your medical therapy.
