What is sleep apnea?

Sleep apnea is a common but serious condition that causes breathing to stop and start repeatedly during sleep. It often shows up as loud snoring, restless nights, and feeling groggy even after a full night’s rest. At One Smile Orthodontics, we take a thoughtful, team-based approach to identifying and supporting patients with sleep-disordered breathing. Dr. Kim uses airway-conscious orthodontic techniques to help open the airway, improve sleep quality, and support better health—especially for growing kids and tired adults alike. Because when you sleep better, everything else feels easier.

The benefits of sleep apnea treatment

Better sleep

By addressing the root cause of airway obstruction, treatment can reduce nighttime interruptions for both children and adults—so everyone wakes up feeling truly rested and ready for the day.

More energy

When kids and adults sleep soundly, their bodies have the chance to fully recharge. That means brighter mornings, improved focus at school or work, better moods, and more energy to take on the day.

Fewer health risks

Sleep apnea isn’t just about snoring—for children or adults. It’s linked to heart health, high blood pressure, behavioral challenges, and more. Treating it early helps protect long-term wellness at every stage of life.

Our sleep apnea treatments

Expanders

Orthodontic expanders gently widen the upper jaw, which can increase space in the nasal cavity and airway. This approach is especially effective for younger patients whose facial bones are still developing. By expanding the airway early, we can help set the stage for better breathing and long-term sleep health.

MARPE

MARPE is a more advanced type of expander designed for older teens and adults. Using small, temporary implants, it enables greater expansion of the palate when traditional expanders are no longer effective. This can improve airflow and help reduce obstructions that contribute to sleep apnea.

Orthognathic surgery

In more severe cases, surgical correction may be needed for both children and adults. Orthognathic surgery adjusts the bones of the jaw and face to create a permanent change in the airway structure, helping improve long-term breathing. This option is typically recommended when non-surgical treatments aren’t enough to fully resolve airway obstruction or breathing problems at any age.

Airway analysis

We use advanced 3D imaging to carefully evaluate your airway and identify any structural issues contributing to poor sleep or breathing. This allows Dr. Kim to tailor a treatment plan that’s fully informed by your unique anatomy—so you get care that’s precise and effective from the start.

The sleep apnea treatment process

1

Comprehensive evaluation

Dr. Kim begins with a detailed consultation for both children and adults, which may include 3D imaging and photos to assess jaw development, bite alignment, and airway space. He also listens closely to breathing or sleep concerns at any age that could indicate a compromised airway.

2

Personalized treatment planning

Using the data gathered, Dr. Kim creates a customized treatment plan for kids and adults alike. This may involve orthodontic appliances, braces, or spacers to guide jaw growth in children or improve airway structure and alignment in adults. Each plan is tailored to the patient’s unique needs and stage of development.

3

Orthodontic intervention

Depending on the case, children and adults may benefit from appliances such as expanders, space maintainers, or braces to encourage proper growth and alignment. These treatments aim to open the airway, improve breathing, and create a healthy, balanced bite at any age.

4

Monitoring and ongoing support

As treatment progresses, Dr. Kim closely tracks facial development in children and structural improvements in adults, along with airway function and overall oral health. He works with patients and families every step of the way to ensure the best possible outcomes for both health and aesthetics.

Frequently asked questions

Find answers to common questions from our clients.

Common signs include loud snoring, waking up gasping for air, frequent headaches in the morning, daytime fatigue, and trouble focusing. Many people aren’t aware they have it until a partner or family member notices pauses in breathing or restless sleep patterns.

Airway-focused orthodontics is especially effective for children and teens, since their jaws are still developing and can be guided more easily. But adults aren’t left out—there are more definitive solutions available for mature jaws, such as MARPE or orthognathic surgery. Dr. Kim works closely with each patient to find the right approach, whether that’s early intervention or adult-focused care designed to improve breathing and long-term wellness.

Some patients notice better sleep and energy levels shortly after starting treatment. However, the timeline can vary based on your specific condition and the treatment plan. Dr. Kim and the team will guide you every step of the way and make adjustments as needed to ensure steady progress.

Real stories.

If you are an adult patient who is considering a ortho treatment that you've been thinking about for your entire life, I highly recommend Dr. Kim. I was initially nervous about the process but Dr.Kim was very attentive and took time to come up with the plan that will address my concerns so I decided to start the treatment. My two main concerns were crowded lower anterior teeth and narrow upper jaw. Before starting the treatment, Dr. Kim clearly explained the treatment plan and timeline, which helped alleviate my concerns. Since I didn't want to wear the palate expander, Dr. Kim came up with alternative solution that can be done with Invisalign. Even as a first time ortho patient, I felt treatment plan was well thought out and precisely moving my teeth without causing excessive pain. I'm currently done with my initial treatment and waiting for refinements sets but I'm already very happy with the results so far. One Smile Orthodontics truly lives up to its name.

I don't normally leave reviews, but after visiting Dr. Namgu Kim I feel compelled to share it.

I went for a consultation about possibly getting braces or Invisalign, and as someone who always had a lot of anxiety around dental visits, I was honestly nervous walking in. But the moment I met Dr. Kim, I felt at ease. He has a reassuring presence and a genuine way of listening that makes you feel cared for as a patient -- not rushed, not pressured, just understood.

Dr. Kim took the time to thoroughly examine my teeth, explain what he was seeing, and walk me through my options in a way that was clear and easy to understand. He pointed out details that other dentists had overlooked and laid out a step-by-step plan that made me feel confident about what comes next. He focused on what would genuinely serve my needs and comfort level. As someone with dental anxiety, that meant a lot. For the first time, I felt like I was in the hands of a specialist who really prioritized my well-being.

If you're considering orthodontic treatment -- Invisalign, braces, or even just a professional opinion -- I cannot recommend Dr. Namgu Kim highly enough. His expertise is exceptional, his communication is clear, and his compassion is unmatched. I walked out feeling informed, supported, and surprisingly excited about the next steps. Thank you!
