Airway & Sleep

How you breathe shapes how you sleep, how you feel, and how your face develops. Dr. Kim looks at your airway as part of every evaluation — because it's not a separate concern.

Breathing affects everything

Most people don't think of their orthodontist when they think about sleep quality, fatigue, or difficulty breathing at night. But the relationship between jaw structure, oral anatomy, and airway function is real — and it's often overlooked in practices focused solely on tooth alignment.

At our Evanston practice, airway is part of the evaluation, not an afterthought. Dr. Kim assesses airway function as part of every comprehensive exam — because the position of the jaw, the size of the palate, and the structure of the airway are all interconnected. A treatment plan that improves alignment without considering airway may miss something important.

For patients with known airway concerns — snoring, sleep apnea, mouth breathing, or related symptoms — we offer targeted treatment options, often in coordination with your physician or sleep specialist.

Restful, healthy sleep

When airway may be a factor

Many patients with airway concerns don't realize there's a structural component to what they're experiencing. These are common signs that warrant an airway evaluation alongside orthodontic assessment:

Snoring

Regular or loud snoring — particularly with pauses in breathing — can indicate airway obstruction during sleep.

Daytime fatigue despite adequate sleep

Waking unrefreshed, difficulty concentrating, or persistent tiredness can be signs that sleep quality is being disrupted by airway events.

Mouth breathing

Habitual mouth breathing — especially in children — can affect jaw development, facial structure, and sleep quality over time.

Diagnosed sleep apnea

Obstructive sleep apnea has a structural component — the airway collapses during sleep. Orthodontic and oral appliance treatment can be a meaningful part of a comprehensive management plan.

In children: behavioral and attention concerns

Sleep-disordered breathing in children is associated with attention difficulties, behavioral issues, and poor academic performance — all of which can improve when the underlying airway issue is addressed.

Narrow palate or jaw

A narrow upper jaw can restrict the nasal airway and contribute to breathing difficulties. Palatal expansion — particularly when done early — can meaningfully improve airway volume.

What we can do

Oral Appliance Therapy

A custom-fabricated device worn during sleep that repositions the lower jaw to keep the airway open. An effective alternative to CPAP for many patients with mild to moderate obstructive sleep apnea — and significantly easier to tolerate for patients who struggle with CPAP compliance.

We work closely with your physician or sleep specialist to ensure the appliance is calibrated appropriately and that treatment outcomes are monitored.

Palatal Expansion

Widening the upper jaw creates more space inside the nasal airway. For children, this is best accomplished during growth — but adult expansion is also possible in some cases. Expansion can reduce nasal resistance, decrease mouth breathing, and improve overall airway volume.

Airway-Aware Orthodontics

For patients undergoing comprehensive orthodontic treatment, Dr. Kim considers airway impact throughout treatment planning. Tooth movements and jaw positioning decisions are made with airway consequences in mind — not just aesthetic or bite outcomes.

Coordinated Care

Airway treatment rarely falls to a single provider. We coordinate with ENTs, sleep physicians, myofunctional therapists, and primary care providers to ensure patients receive a comprehensive approach — not just a piece of one.

An honest note

Orthodontic treatment is not a standalone solution for obstructive sleep apnea. It can be a meaningful part of a comprehensive treatment plan, but it should be coordinated with a physician who has confirmed the diagnosis and is overseeing your care. We'll tell you clearly what we can contribute — and refer you appropriately for the rest.

Airway is part of every evaluation at Smile Suite.
