What is Sleep Apnea?

Sleep apnea is a sleep disorder that affects millions of people throughout the world. Sleep apnea is characterized by pauses in breathing during sleep, which can last anywhere from a few seconds to minutes and can occur multiple times throughout the night. These pauses are caused by obstructions or blockages in the airway, resulting in reduced or even completely restricted airflow. As a result, the brain and body are deprived of oxygen, leading to disrupted sleep patterns and potential health risks. Because of these disrupted sleep patterns, sleep apnea can affect your quality of life as sufferers are deprived of much needed rest.

Causes of Sleep Apnea

Sleep apnea comes in two main forms: obstructive sleep apnea (OSA) and central sleep apnea (CSA). OSA is the more common type and occurs when the muscles in the throat relax, causing the airway to become narrow or completely blocked. CSA is a less common type of sleep apnea and happens when the brain fails to send signals to the muscles that control breathing during sleep. Here at Oak Hills Dentistry, located south of The Woodlands, Texas, Dr. Reagan Smith focuses on working with and treating patients with OSA.

Health Risks of Sleep Apnea

Sleep apnea, if left untreated, can lead to a myriad of other health problems. Chronic sleep deprivation resulting from sleep apnea can lead to daytime fatigue, difficulty concentrating, and can significantly impact your quality of life. Some of the various health risks associated with sleep apnea include:

  • Increased risk of high blood pressure
  • Increased risk of heart attack
  • Increased risk of stroke
  • Potential for obesity
  • Heightened risk of diabetes
  • Potential to lead to, or worsen, heart failure
  • Severe effects on mood, potentially leading to depression or anxiety

Evaluation and Consultations

The goal of sleep apnea treatment is to restore regular breathing patterns during sleep, ensuring that the brain and body receive enough oxygen, improving restfulness and quality of life. While lifestyle changes can often help, one of the best treatments for mild to moderate sleep apnea is correcting the positioning of the airway through a mouthguard, also called Oral Appliances or Sleep Appliances. 

Though sleep apnea is diagnosed by a medical doctor, with Dr. Smith’s expertise and our advanced diagnostic technology, we’re equipped to thoroughly evaluate your condition and determine an effective treatment plan tailored to your specific needs. Our state-of-the-art diagnostic tools include a microTENS unit, which can relax the muscles of the jaw and neck to establish a physiologically ideal jaw position, as well as recording EMGs to measure muscle activity.

Dr. Smith works closely with each patient to determine the best treatment approach based on their individual needs and preferences.

  • Improved Daytime Functioning: As a result of better sleep, patients may feel more alert and focused during the day
  • Reduced Health Risks: Proper treatment of sleep apnea can significantly diminish the risk of associated health complications like heart disease, stroke, and high blood pressure.
  • Enhanced Mood: With improved quality of sleep, patients often report a decrease in feelings of depression or anxiety, leading to an overall better mood and outlook.
  • Weight Control: Improved sleep can help regulate hormones that control appetite, assisting in weight management.
  • Increased Energy: Uninterrupted sleep often translates to higher energy levels throughout the day, allowing patients to engage more in physical activities and enjoy a more active lifestyle.
