A Better Night's Sleep Starts With the Right Treatment

People who have sleep apnea never get the rest they deserve. The condition disrupts breathing repeatedly throughout the night, robbing the body of the deep, restorative sleep it needs to function. The consequences extend well beyond feeling tired in the morning. Untreated sleep apnea has serious and wide-ranging effects on both physical health and quality of life.

At Lifetime Dentistry in Muscatine, Iowa, Dr. Holly Krystek provides custom oral appliance therapy as a comfortable and effective treatment option for patients with obstructive sleep apnea and snoring. An oral appliance is a small, custom-fitted device worn during sleep that keeps the airway open and allows for uninterrupted breathing throughout the night.

We serve patients from Muscatine and surrounding communities including Fairport, Durant, Wilton, Wapello, Grandview, Letts, BluGrass, and neighboring areas throughout Iowa and Illinois.

What is Obstructive Sleep Apnea?

Obstructive sleep apnea, commonly referred to as OSA, is a chronic condition that occurs when the muscles of the throat relax during sleep, allowing soft tissue to collapse and partially or fully block the airway. This obstruction restricts or completely stops airflow, causing oxygen levels in the blood to drop.

The reduction in oxygen triggers the body to wake briefly to restore normal breathing, often accompanied by snorting, gasping, or choking sounds. These episodes can occur an average of 30 or more times per hour in severe cases, and the person experiencing them typically has no memory of waking up. The result is a night filled with constant micro-interruptions that prevent the body from reaching the deep, restorative stages of sleep it needs.

Each episode of reduced airflow can last anywhere from a few seconds to several minutes. The cumulative effect of these recurring oxygen drops over months and years places serious stress on the cardiovascular system and other vital organs.

What Causes Sleep Apnea?

Sleep apnea can develop for a variety of anatomical and lifestyle-related reasons. Understanding the contributing factors helps identify patients who may be at risk and supports more targeted treatment planning.

Common causes and risk factors for obstructive sleep apnea include:

A misaligned or small jaw that positions the tongue close to the back of the throat
Excess body weight, particularly around the neck and throat, which narrows the airway
A naturally narrow airway structure
A tongue with scalloped edges, which may indicate habitual pressing against the teeth due to airway restriction
Enlarged tonsils or adenoids
Nasal congestion or structural nasal issues that impair breathing
Sleeping on the back, which allows the tongue and soft tissue to fall toward the throat
Alcohol consumption before bed, which relaxes throat muscles further
Family history of sleep apnea
Being male, middle-aged, or postmenopausal, all of which increase statistical risk

Getting Your Custom Oral Appliance at Our Muscatine Office

The process of receiving a custom oral appliance at Lifetime Dentistry begins with a thorough evaluation to confirm that oral appliance therapy is appropriate for your specific situation.

Consultation and Evaluation

Dr. Krystek reviews your sleep apnea diagnosis, medical history, and any prior treatment attempts. A clinical examination of your teeth, jaw, and airway anatomy is performed to assess your suitability for an oral appliance. Patients who have not yet received a formal sleep apnea diagnosis may be referred for a sleep study before oral appliance therapy is initiated.

1

Impressions and Fabrication

Precise impressions or digital scans of your teeth are taken and used to fabricate a custom appliance that fits your mouth exactly. The device is made to position the jaw at a specific, therapeutically effective angle while remaining comfortable enough to wear throughout the night.

2

Fitting and Adjustment

When the appliance is ready, Dr. Krystek ensures the fit is accurate and comfortable and provides detailed instructions on use and care. Follow-up appointments allow for any adjustments needed to optimize both comfort and effectiveness. Ongoing monitoring ensures the appliance continues to function as intended over time.

Benefits of Oral Appliance Therapy

An oral appliance is a small, custom-fitted device that resembles a sports mouth guard or orthodontic retainer. It is worn during sleep and works by gently repositioning the lower jaw and tongue slightly forward, which opens the airway and prevents the soft tissue collapse that causes sleep apnea. By maintaining a clear, unobstructed airway throughout the night, the appliance allows for consistent, uninterrupted breathing and eliminates the oxygen drops that drive the health consequences of OSA.

Key advantages of oral appliance therapy include:

Small, discreet, and easy to travel with
Silent, unlike CPAP machines which many patients find disruptive
No masks, hoses, or equipment required
Custom-fitted for comfort and precise effectiveness
Easy to clean and maintain
High patient compliance rates compared to CPAP therapy
Suitable for patients with mild to moderate OSA and for CPAP-intolerant patients

Frequently Asked Questions About Sleep Apnea & Oral Appliance Therapy

Common signs include loud snoring, waking up gasping or choking, persistent morning headaches, daytime fatigue despite a full night in bed, difficulty concentrating, and being told by a partner that you stop breathing during sleep. A formal diagnosis requires a sleep study, which measures breathing patterns, oxygen levels, and sleep quality over the course of a night. Dr. Krystek can discuss your symptoms and refer you for a sleep study if one has not already been completed.

For patients with mild to moderate obstructive sleep apnea, oral appliances have been shown to be highly effective at reducing the frequency and severity of apnea episodes. CPAP therapy remains the standard treatment for severe OSA, but many patients find CPAP difficult to tolerate consistently. An oral appliance that is worn reliably every night is clinically more beneficial than a CPAP machine that goes unused. Dr. Krystek works with your physician or sleep specialist to determine which approach is most appropriate for your diagnosis.

Most patients adapt to wearing an oral appliance within a short period of time. Because the device is custom-fitted to your teeth and jaw, it is far more comfortable than a generic alternative. Some patients experience mild jaw soreness or increased saliva in the first few days, both of which typically resolve as the mouth adjusts. Follow-up appointments allow Dr. Krystek to make any refinements needed to optimize comfort.

Rinse the appliance with cool water each morning and clean it gently with a soft toothbrush and mild soap or a non-abrasive denture cleaner. Allow it to air dry completely before storing it in its case. Avoid exposing it to hot water or direct sunlight, which can warp the material. Bring the appliance to your regular dental checkups so Dr. Krystek can inspect its condition and confirm it is still fitting and functioning correctly.

Coverage for oral appliance therapy varies by plan and depends on whether a formal sleep apnea diagnosis has been established. Many medical insurance plans, including Medicare, provide coverage for oral appliance therapy when prescribed for diagnosed OSA. Dental insurance may also contribute depending on the policy. Our front office team is happy to help review your coverage before treatment begins.
