Do Mouthguards Really Work for Sleep Apnea?

Battling Sleep Apnea the Easy Way: Could a Mouthguard Be Your Answer?

In Australia, it’s estimated that around 5% of adults suffer from sleep apnea, though many cases remain undiagnosed. If you wake up feeling groggy, experience excessive daytime fatigue, or have been told you snore loudly, sleep apnea could be the culprit. The good news? A simple mouthguard might be all it takes to get you sleeping soundly again. But how effective are these devices, and could they work for you? Let’s dive in and explore.

Understanding Sleep Apnea

Sleep apnea is a common but serious sleep disorder characterised by repeated interruptions in breathing during sleep. These interruptions, called apneas, can last from a few seconds to minutes and occur dozens of times an hour. Sleep apnea leads to poor-quality sleep and can contribute to various health complications, such as:

  •  High blood pressure

  • Cardiovascular disease

  • Diabetes

  • Depression and anxiety

  • Excessive daytime fatigue, which increases the risk of accidents

 

The most common form is obstructive sleep apnea (OSA), which occurs when throat muscles relax excessively and block the airway during sleep. For Australians, sleep apnea remains a growing concern due to increasing rates of obesity and sedentary lifestyles—both significant risk factors. 

What Is a Sleep Apnea Mouthguard?

A sleep apnea mouthguard, also known as an oral appliance, is a device designed to treat mild to moderate OSA. It’s worn in the mouth while you sleep and works by keeping your airway open. This is typically achieved in two main ways:

 

1. Repositioning the lower jaw (mandible) forward to prevent airway collapse.

2. Holding the tongue in place to avoid it blocking the airway.

 

These devices are non-invasive and are often seen as an alternative to CPAP therapy, especially for those who struggle to use CPAP machines consistently.

Types of Sleep Apnea Mouthguards 

There are two primary types of oral appliances for sleep apnea:

1. Mandibular Advancement Devices (MADs)

These are the most common type. MADs move the lower jaw forward to create more space in the airway, reducing obstructions. They are adjustable and custom-fitted to ensure maximum effectiveness and comfort.

2. Tongue Retaining Devices (TRDs)

TRDs are ideal for people whose tongues are the main source of airway obstruction. These devices keep the tongue in a forward position using suction, preventing it from collapsing into the throat.

Effectiveness of Sleep Apnea Mouthguards

Mouthguards are highly effective for treating mild to moderate OSA. Studies, such as those published in the Journal of Clinical Sleep Medicine, show that oral appliances can significantly reduce the apnea-hypopnea index (AHI) and improve overall sleep quality.

Key Benefits:

  • Reduction in snoring

  • Improved oxygen levels during sleep

  • Enhanced daytime alertness

  • Decrease in long-term health risks associated with untreated sleep apnea

However, for severe sleep apnea, a CPAP machine remains the gold standard due to its higher success rates in keeping the airway fully open throughout the night.

Pros and Cons of Using a Sleep Apnea Mouthguard

Pros:

  • Non-Invasive Solution: No surgery or complex procedures required.

  • Convenient and Portable: Easy to carry when travelling, unlike bulky CPAP machines.

  • Simple to Use: Once fitted, requires minimal effort.

Cons:

  • Limited for Severe OSA: Not as effective as CPAP for severe cases.

  • Adjustment Period: May cause temporary jaw discomfort, excessive salivation, or teeth shifting.

  • Maintenance Required: Periodic adjustments and replacements are necessary to ensure continued effectiveness.

Choosing the Right Mouthguard

Selecting the right mouthguard is crucial to achieving the desired results. In Australia, working with a dentist who specialises in oral appliance therapy for sleep apnea is essential. Custom-fitted devices, created based on impressions of your teeth and jaw, are far superior to over-the-counter options. They provide:

  • Better comfort

  • More effective results

  • Longer durability

Alternatives to Mouthguards

While sleep apnea mouthguards are a great option for many, they’re not the only treatment available. Here are some alternatives:

  • CPAP Therapy: The most effective treatment for severe OSA. It uses a machine to deliver a continuous stream of air to keep your airway open.

  • Lifestyle Changes: Weight loss, regular exercise, and quitting smoking can reduce sleep apnea severity.

  • Surgical Options: Procedures like uvulopalatopharyngoplasty (UPPP) or Inspire Therapy may be considered for severe cases.

 

Conclusion: Are Sleep Apnea Mouthguards Worth It?

For Australians with mild to moderate sleep apnea, a sleep apnea mouthguard offers a convenient, effective, and non-invasive solution. By improving airflow and reducing symptoms like snoring and fatigue, these devices can significantly enhance your quality of life.

However, it’s crucial to consult a healthcare professional to determine whether this treatment suits your condition. Severe cases may require alternative treatments like CPAP therapy or surgery.

If you suspect you have sleep apnea, don’t wait. Speak to a dentist who specialises in oral appliances today and take the first step towards better sleep and improved health.

Frequently Asked Questions

1. How do I know if I have sleep apnea?

Common symptoms include loud snoring, waking up gasping for air, morning headaches, and feeling excessively tired during the day. A sleep study is typically required for a proper diagnosis.

2. Can I buy a mouthguard online?

While over-the-counter mouthguards are available, they are generally less effective. A custom-fitted device from a qualified dentist is recommended for the best results.

3. Is a mouthguard better than CPAP therapy?

For mild to moderate OSA, a mouthguard may be an effective alternative. However, for severe cases, CPAP remains the preferred treatment.
