5 Myths of Using OA

Sleep apnea is a common sleep disorder that affects millions of people worldwide. It can lead to serious health issues, including heart disease, high blood pressure, and daytime fatigue. While continuous positive airway pressure (CPAP) machines are a well-known treatment option, many people are turning to sleep apnea oral appliances as an alternative. However, there are several myths and misconceptions surrounding these devices. In this blog, we'll debunk five common myths about sleep apnea oral appliances.

Myth #1: Oral Appliances Are Only for Mild Sleep Apnea

One of the most prevalent myths about sleep apnea oral appliances is that they are only suitable for individuals with mild sleep apnea. This misconception stems from the belief that more severe cases of sleep apnea require the use of a CPAP machine to provide continuous airflow.

Reality: Sleep apnea oral appliances are not limited to mild cases of sleep apnea. While CPAP machines are highly effective, oral appliances can also be used to treat moderate to severe sleep apnea. Many patients who suffer from severe apnea have multiple areas of obstruction in the upper airway.  By correctly addressing the obstructions, an oral appliance can lead to successful treatment. Many patients who cannot tolerate a CPAP device opt for a sleep apnea oral appliance.

Myth #2: Sleep Apnea Oral Appliances Always Cause TMJ Problems

One of the most prevalent myths about sleep apnea oral appliances is the assumption that they can lead to TMJ issues.

Reality: While it is possible for some individuals to experience TMJ discomfort when using an oral appliance, it’s incorrect to assume an oral appliance that is correctly designed will cause TMD (temporomandibular dysfunction).

The keys to avoiding TMJ problems lie in proper diagnosis and professional guidance.  A customized appliance is designed not only for your teeth but also to fit the jaw joint and movement. Dentists who specialize in sleep apnea treatment should carefully assess a patient's dental, jaw, and craniofacial structures to design the oral appliance correctly. They also should have a thorough understanding of TMJ treatment modalities, given that many patients who suffer from obstructive sleep apnea also clench and grind their teeth. Regular follow-up visits with your dental professional can help ensure that any potential TMJ issues are addressed promptly. At Modern Sleep Solution, we have been treating TMJ patients successfully for more than a decade using sleep apnea oral appliances.

Myth #3: Oral Appliances Are Uncomfortable to Wear

Another myth is that sleep apnea oral appliances are inherently uncomfortable, leading to difficulties in adapting to their use.

Reality: Like any medical device, there is an adjustment period when using a sleep apnea oral appliance. However, most people find them comfortable once they get used to wearing them. These devices are custom-made to fit each patient's mouth, which helps minimize discomfort. It's crucial to work closely with a qualified dentist or dental specialist who can make necessary adjustments to improve comfort and effectiveness.

Myth #4: Oral Appliances Are Less Effective than CPAP

Some individuals believe that oral appliances are less effective than CPAP machines in treating sleep apnea.

Reality: While CPAP therapy is highly effective for many sleep apnea patients, oral appliances can also be a viable treatment option. The effectiveness of an oral appliance depends on factors such as the severity of sleep apnea and patient compliance. For those with mild to moderate sleep apnea, or those who find CPAP uncomfortable or challenging to use consistently, oral appliances can provide significant relief. Many studies have shown that properly fitted oral appliances can effectively reduce apnea events and improve sleep quality.

Myth #5: Oral Appliances Are One-Size-Fits-All

A common misconception is that all sleep apnea oral appliances are the same and do not require customization.

Reality: Sleep apnea oral appliances are not one-size-fits-all. Each person's mouth and dental structure are unique, necessitating a custom-made oral appliance. The customization process involves taking impressions of the patient's mouth and designing an appliance that fits comfortably and effectively. This tailored approach ensures the appliance's effectiveness in keeping the airway open during sleep.


Sleep apnea oral appliances are a valuable and effective treatment option for many individuals with sleep apnea. It is crucial to dispel myths and misconceptions surrounding these devices to help patients make informed decisions about their treatment. While concerns about TMJ problems, discomfort, and effectiveness are common, working closely with a qualified dental professional can address these issues and lead to successful outcomes. Always ask how many sleep apnea oral appliances the “qualified dental professional” has successfully fitted over how many years.
