Sleep apnea is a serious sleep disorder in which breathing repeatedly stops and starts during sleep. The most common form — obstructive sleep apnea (OSA) — occurs when the muscles in the back of the throat relax excessively, causing the airway to narrow or close completely. Each breathing pause can last 10 seconds or longer and may occur 30 or more times per hour, fragmenting sleep and reducing blood oxygen levels. An estimated 30 million Americans have sleep apnea, yet roughly 80% of moderate-to-severe cases remain undiagnosed.

Sleep apnea is a sleep disorder where breathing repeatedly stops and starts during sleep. Obstructive sleep apnea (OSA) is the most common type, caused by relaxation of throat muscles that block the airway. Oral appliance therapy is a CPAP alternative for mild to moderate cases, using a custom-fitted device to keep the airway open during sleep.
Sleep apnea causes your breathing to stop and restart dozens — sometimes hundreds — of times each night. These interruptions prevent your body from reaching the deep, restorative stages of sleep that are essential for physical recovery, memory consolidation, and cardiovascular health.
Obstructive sleep apnea is the most common type, accounting for roughly 84% of all cases. It occurs when the soft tissues at the back of the throat — the tongue, soft palate, and pharyngeal muscles — relax during sleep and collapse into the airway, partially or completely blocking airflow. Risk factors include excess weight (particularly around the neck), a naturally narrow airway, nasal congestion, enlarged tonsils, a recessed jaw, smoking, and alcohol use before bed. OSA is significantly more prevalent in men, though post-menopausal women face rising risk. The condition is diagnosed based on the apnea-hypopnea index (AHI): 5–14 events per hour is mild, 15–30 is moderate, and above 30 is severe.
Central sleep apnea is less common and occurs when the brain fails to send the proper signals to the muscles that control breathing. Unlike OSA, there is no physical blockage — the body simply "forgets" to breathe. CSA is more often associated with heart failure, stroke, opioid use, and certain neurological conditions. Some patients have complex (mixed) sleep apnea that combines elements of both obstructive and central types. Central sleep apnea is managed by a sleep medicine physician and typically requires different treatment approaches than OSA. Oral appliance therapy primarily addresses obstructive sleep apnea.
Prevalence: The American Academy of Sleep Medicine estimates that approximately 30 million adults in the United States have obstructive sleep apnea. Among adults over 50, prevalence may reach 25–30%. Despite these numbers, roughly 80% of moderate-to-severe cases remain undiagnosed — making sleep apnea one of the most under-recognized conditions in medicine.
Real experiences from patients who trust Innova Smiles with their care.
Many patients live with these symptoms for years without realizing they point to a treatable condition. If several of these sound familiar, a sleep evaluation is a worthwhile next step.
Snoring loud enough to disturb a bed partner is the most common sign of obstructive sleep apnea.
Excessive daytime sleepiness despite a full night in bed — a hallmark of fragmented, oxygen-deprived sleep.
Waking with dull, pressing headaches caused by overnight drops in blood oxygen and increased CO2 levels.
Waking suddenly with a choking or gasping sensation as your airway reopens after an apnea event.
Breathing through your mouth during apnea events dries out oral tissues, increasing cavity and gum disease risk.
Brain fog, memory lapses, and trouble focusing — caused by repeated oxygen deprivation during sleep.
Chronic sleep disruption affects mood regulation, often leading to irritability, anxiety, or depression.
Untreated sleep apnea strains the cardiovascular system, contributing to resistant hypertension.
Sleep apnea is frequently first noticed by a bed partner who observes loud snoring, breathing pauses, or gasping episodes during the night. If someone close to you has mentioned any of these, take it seriously — their observation may be the most important diagnostic clue you receive. Many patients are unaware their sleep is disrupted because apnea events rarely bring them to full wakefulness.
Untreated sleep apnea does far more than ruin your sleep. The repeated oxygen drops and cardiovascular stress it creates affect nearly every system in your body, compounding over time into serious, potentially life-threatening conditions.
Each apnea event triggers a surge in blood pressure and heart rate. Over months and years, this repetitive stress increases the risk of hypertension, atrial fibrillation, heart attack, and stroke. The American Heart Association recognizes sleep apnea as an independent risk factor for cardiovascular disease.
Sleep apnea disrupts glucose metabolism and increases insulin resistance. Research published in the American Journal of Respiratory and Critical Care Medicine shows that moderate-to-severe OSA significantly raises the risk of developing type 2 diabetes, even after controlling for obesity.
Repeated oxygen desaturation damages brain tissue over time. Studies link untreated sleep apnea to accelerated cognitive decline, impaired memory consolidation, and an increased risk of dementia — particularly in patients over 50.
The excessive daytime sleepiness caused by untreated sleep apnea impairs reaction time comparable to alcohol intoxication. The National Highway Traffic Safety Administration estimates drowsy driving causes thousands of crashes annually, and OSA patients are 2-3 times more likely to be involved in motor vehicle accidents.
The good news: treating sleep apnea — through oral appliance therapy, CPAP, or other interventions — can significantly reduce these risks. Studies show that consistent treatment lowers blood pressure, improves glucose control, restores cognitive function, and reduces accident risk. The sooner treatment begins, the greater the benefit.
For patients with mild to moderate obstructive sleep apnea — or those who cannot tolerate CPAP — a custom-fitted oral appliance offers a comfortable, portable, and highly effective treatment option.
A mandibular advancement device (MAD) is a custom-fabricated oral appliance that fits over the upper and lower teeth — similar to a sports mouthguard, but precision-engineered for airway therapy. The device gently advances the lower jaw forward by several millimeters, which tightens the soft tissues and muscles of the upper airway and prevents them from collapsing during sleep.
This forward positioning also moves the tongue base away from the back of the throat, further widening the airway. The result is unobstructed breathing throughout the night — without the mask, hose, or machine noise that cause many patients to abandon CPAP therapy.
The American Academy of Sleep Medicine recommends oral appliance therapy as a first-line treatment for mild to moderate obstructive sleep apnea, and as an alternative for patients with severe OSA who are unable to use CPAP. You may be an ideal candidate if:
Both treatments are effective. The best choice depends on your diagnosis, severity, anatomy, and personal preferences. A sleep study and consultation will determine the optimal approach.
From initial consultation to confirmed treatment success — here is exactly how we guide you through sleep apnea evaluation and oral appliance therapy.
We assess your symptoms, review your medical history, and evaluate your airway anatomy. If sleep apnea is suspected, we coordinate a sleep study referral with your physician or a board-certified sleep medicine specialist.
A home sleep test or in-lab polysomnography confirms the presence and severity of obstructive sleep apnea (mild, moderate, or severe) using the apnea-hypopnea index (AHI).
For patients with mild to moderate OSA — or those who cannot tolerate CPAP — we take precise digital impressions and fabricate a custom mandibular advancement device designed to keep your airway open during sleep.
We fine-tune the appliance position over several follow-up visits, adjusting the mandibular advancement to optimize airway opening while maintaining comfort. A follow-up sleep study confirms treatment efficacy.
