Sleep Apnea Treatment in Little Rock, AR | Symmetry Modern Dentistry

Sleep apnea is not simply a snoring problem. It is a systemic condition in which repeated breathing disruptions during sleep — sometimes hundreds of times per night — deprive the brain and body of oxygen, fragment sleep architecture, and trigger a chronic stress response that compounds into serious cardiovascular, metabolic, and cognitive consequences over time.

At Symmetry Modern Dentistry, Dr. Stephen Deal brings 23 years of clinical experience and a level of specialization found nowhere else in Arkansas. As the state’s only double board certified practitioner in both Craniofacial Pain and Dental Sleep Medicine, Dr. Deal approaches sleep apnea not as a symptom to be managed, but as a structural condition to be understood and treated at its source.

Understanding the Diagnosis: AHI, RDI, and What Your Sleep Report Actually Means

Most patients who are diagnosed with sleep apnea receive a number called an Apnea-Hypopnea Index (AHI) — a count of breathing pauses per hour of sleep. Mild sleep apnea begins at 5 events per hour. Moderate is 15–29. Severe is 30 or more. Even mild sleep apnea warrants evaluation; the cumulative health toll of untreated mild OSA is well established.

What many patients are never told: the AHI is not the only relevant number.

The Respiratory Disturbance Index (RDI) goes further, counting not just full breathing pauses but also Respiratory Effort-Related Arousals (RERAs) — brief surges in breathing effort that fragment sleep without causing a complete pause. A patient with a low AHI but an elevated RDI may still be experiencing significant sleep disruption that goes completely untreated when RDI is ignored.

There is also a critical scoring variable that affects whether your sleep study accurately reflects your disease severity: the oxygen desaturation threshold. The American Academy of Sleep Medicine (AASM) recommends a 3% threshold for counting a breathing event. Many insurance companies require a 4% drop — a stricter standard that systematically suppresses the reported AHI, making sleep apnea appear less severe than it truly is, and providing justification to deny or limit coverage. Patients scored at the 4% threshold may be significantly under-diagnosed. We interpret your results in clinical context.

When Your Sleep Study Is “Normal” But You’re Still Exhausted

Upper Airway Resistance Syndrome (UARS) is one of the most under-diagnosed sleep disorders in medicine. In UARS, the airway narrows enough to increase resistance and trigger arousal from sleep — but not enough to cause the oxygen drops or complete pauses that define obstructive sleep apnea. The AHI remains below the diagnostic threshold. The sleep study reads as normal. The patient is sent home still exhausted.

• UARS was first characterized by Dr. Christian Guilleminault at Stanford University, whose research established that the upper airway does not need to collapse completely to devastate sleep quality. More recently, Dr. Soroush Zaghi — Harvard Medical School graduate, ENT and Sleep Surgery Fellow at Stanford, and Medical Director of The Breathe Institute — has built on that foundation with landmark meta-analyses quantifying how structural corrections to the jaw and palate reduce sleep-disordered breathing at scale.
• UARS disproportionately affects women, younger adults, and patients with normal BMI — patients who are frequently told there is nothing wrong with their sleep, and who cycle through misdiagnoses of anxiety, depression, fibromyalgia, or chronic fatigue syndrome for years. Common UARS symptoms include:
• Chronic unrefreshing sleep despite adequate hours
• Severe daytime fatigue and brain fog
• Morning headaches
• Insomnia or fragmented sleep
• Anxiety and emotional dysregulation
• Cold hands and feet (autonomic signs)
• Irritable bowel syndrome
• Mild or absent snoring

If this profile sounds familiar, UARS may be what has been missed. Dr. Deal evaluates both AHI and RDI to ensure nothing is overlooked.

The Sleep Apnea–TMJ Connection

The jaw and the airway are anatomically inseparable. When the jaw is underdeveloped, set back, or misaligned, the tongue and soft tissues have less room — and the airway pays the price.

When the airway narrows during sleep, the brain triggers a compensatory response: the jaw moves forward, muscles activate, and the patient grinds or clenches to reopen the airway. This is not stress. This is the brain attempting to breathe. The result is a patient with a sore jaw, chronic headaches, disrupted sleep, and no clear explanation — because no one has looked at the jaw and the airway together.

Dr. Deal treats the jaw-airway relationship as a single clinical system. Patients who have been managing TMJ symptoms for years without relief frequently discover that untreated sleep-disordered breathing was the unaddressed driver.

Sleep Apnea in Children — Early Signs and Why They Matter

Pediatric sleep apnea is common, frequently missed, and more consequential than most parents realize. Children’s brains and bodies depend on deep, restorative sleep for cognitive development, emotional regulation, and physical growth. When the airway is obstructed — even partially — the consequences compound quietly over years.

• Signs of sleep-disordered breathing in children include:
• Snoring or noisy breathing during sleep
• Mouth breathing (day or night)
• Teeth grinding
• Dark circles under the eyes
• Behavioral problems or ADHD diagnosis
• Bedwetting
• Difficulty concentrating or poor academic performance
• Restless sleep or unusual sleeping positions

80% of the population has an undersized upper jaw, which restricts nasal airway volume, forces mouth breathing, and sets the stage for sleep apnea across a lifetime. Addressing jaw development early — before skeletal growth is complete — can alter this trajectory entirely. Dr. Guilleminault’s landmark research at Stanford demonstrated that growth-based treatment produces lasting structural correction; symptom management alone does not.

Treatment Options at Symmetry Modern Dentistry

An accurate diagnosis of your specific sleep disorder precedes any treatment. This begins with a sleep study — either in-lab polysomnography (PSG) or a supervised home sleep test — under the direction of a sleep physician. We communicate directly with your sleep medicine provider to ensure integrated care.

Depending on your evaluation findings, treatment options include:

Oral Appliance Therapy Custom-fabricated devices worn during sleep that reposition the jaw and modify airway dimensions to prevent obstruction. FDA-cleared and highly effective for mild to moderate OSA, oral appliances are also an excellent CPAP alternative for patients who are intolerant of positive airway pressure. Dr. Zaghi’s published meta-analysis found maxillomandibular advancement procedures produce an average 80.1% AHI reduction — the same principle, applied surgically at scale — validating the anatomical rationale behind appliance-based jaw repositioning.

Palatal Expansion A narrow upper jaw restricts nasal airway volume and forces mouth breathing, which dramatically increases airway resistance during sleep. Palatal expansion — non-surgical in children, surgically-assisted in adults — widens the arch and the nasal floor simultaneously, directly expanding nasal airway volume. A 2016 systematic review by Dr. Zaghi (Journal of Cranio-Maxillofacial Surgery) found palatal expansion reduced AHI by 59.3% on average.

Myofunctional Therapy Targeted exercises that rehabilitate tongue posture, lip seal, and nasal breathing. Dr. Deal calls the foundation of this work the “Big 3”: lips together, nasal breathing, and tongue resting on the roof of the mouth. These three habits normalize the functional forces that shape jaw development and keep the airway open during sleep. For myofunctional therapy services, we refer patients to Arkansas Orofacial Therapy.

Airway-Focused Orthodontics Orthodontic treatment planned with explicit airway goals — prioritizing arch development and avoiding unnecessary tooth extractions that reduce arch perimeter and restrict the airway.

Z-Tape by Dr. Deal For patients with mild sleep-disordered breathing or habitual mouth breathing, Dr. Deal’s Z-Tape encourages nasal breathing during sleep by gently maintaining lip closure. Studies show lip taping can reduce sleep-disordered breathing by up to 50% in appropriate candidates. Learn more about Z-Tape →
