Sleep Apnea: what you don’t know can harm you

Sleep apnea is a serious sleep disorder, characterized by repeated interruptions in breathing during sleep, that can harm all parts of the body. It can lead to various health issues, including daytime fatigue, cardiovascular problems, and impaired cognitive function. Many associate this condition with adults, but it can also affect children. While the diagnosis is done by a sleep study with your physician, an orthodontist may often be the first to see this problem in children. Understanding how orthodontic treatment can help manage sleep apnea is crucial for those affected by this condition.

What is Sleep Apnea?

There are two primary types:

1. Obstructive Sleep Apnea (OSA): The most common form, caused by a blockage of the upper airway, usually due to the relaxation of throat muscles and tissues.
2. Central Sleep Apnea: A less common type that occurs when the brain fails to send appropriate signals to the muscles that control breathing.

Symptoms of Sleep Apnea

Common symptoms include:

• Loud snoring
• Gasping or choking during sleep
• Excessive daytime sleepiness
• Morning headaches
• Difficulty concentrating

Risk factors for Sleep Apnea

• Excess weight. Obesity greatly increases the risk of OSA as fat deposits can obstruct your breathing.
• A narrowed airway. You might have inherited a narrow throat. Enlarge tonsils or adenoids can block the airway, particularly in children.
• Being male. Men are 2-3 times more likely to have sleep apnea than are women. However, women increase their risk if they’re overweight or if they’ve gone through menopause.
• Being older. Sleep apnea occurs significantly more often in older adults.
• Family history. Having family members with sleep apnea might increase your risk.
• Use of alcohol, sedatives or tranquilizers. These substances relax the muscles in your throat, which can worsen obstructive sleep apnea.
• Smoking. Smokers are 3 times more likely to have obstructive sleep apnea than non-smokers. Smoking can increase the amount of inflammation and fluid retention in the upper airway.
• Medical conditions. Diabetes, hypertension and asthma are some of the conditions that may be associated with an increased risk.

The Role of Orthodontics in Managing Sleep Apnea

Orthodontic treatment can play a significant role in alleviating obstructive sleep apnea by addressing structural issues in the mouth and jaw. Here’s how:

1. Jaw Alignment: Misalignment of the jaw can contribute to airway obstruction during sleep. Orthodontic treatments, such as braces or aligners, can correct jaw alignment, helping to keep the airway open.
2. Expansion of the Dental Arch: In some cases, expanding the upper jaw (maxillary expansion) can create more space in the oral cavity, allowing for improved airflow and reducing the severity of sleep apnea.
3. Custom Oral Appliances: Orthodontists can create custom oral appliances that help reposition the jaw and tongue during sleep, keeping the airway open. These appliances are often used as an alternative to CPAP machines for mild to moderate cases of OSA.
4. Addressing Malocclusion: Poor bite alignment can affect the positioning of the tongue and soft tissues in the throat. Orthodontic treatment can correct malocclusion, potentially reducing airway obstruction.
5. Early Intervention: In children, orthodontic treatment can address dental and jaw alignment issues early on, potentially preventing the development of sleep apnea later in life.

Additional Considerations

• Comprehensive Evaluation: If sleep apnea is suspected, a comprehensive evaluation by a healthcare professional, including a sleep study, is essential. An orthodontist can work alongside other specialists to create a holistic treatment plan.
• Lifestyle Modifications: Alongside orthodontic treatment, lifestyle changes such as weight management, positional therapy, and avoiding alcohol can also help manage symptoms.

Conclusion

Orthodontic treatment can be a valuable component in managing obstructive sleep apnea. By addressing structural issues in the mouth and jaw, orthodontics can help improve airflow during sleep, leading to better overall health and quality of life. If you or a loved one is experiencing symptoms, consult with a healthcare professional and consider seeking an orthodontic evaluation for potential solutions.
