If you are suffering from depression, a visit to your dentist may not be the first thing that comes to mind. However, according to a study from Western University in London, Ontario, a sleep apnea device can not only cure your sleep disorder, it can ease your depression. Scientists have long known that there is a connection between obstructive sleep apnea (OSA) and depression. They are still uncertain about the exact nature of the connection and whether sleep apnea leads to depression or vice versa. However, they do know that treating OSA can significantly improve a patient’s mood. At our Conroe practice, we can often treat your OSA with an oral appliance, similar to a mouthguard.

What Is Obstructive Sleep Apnea?

Obstructive sleep apnea is a common condition. According to Dr. Anne Wheaton of the CDC, 6% of American men and 3% of American women have been diagnosed with obstructive sleep apnea. Wheaton says that 5% of Americans have undiagnosed severe OSA, and up to 20% have an undiagnosed mild case of the condition. If you have sleep apnea, your soft palate, throat, and/or tongue fall back into your mouth as you sleep, blocking the passage of air. As a result, you will repeatedly wake up during the night, even though you may not know that this is happening. Signs of sleep apnea include daytime sleepiness, headaches, anxiety, irritability, memory loss, and depression.

How a Mouthguard Can Treat OSA and Depression

As stated above, the exact connection between OSA and depression is unclear. Some posit that sleep apnea leads to depression because of the anxiety of chronic exhaustion. Others believe that lack of oxygen could cause brain damage and mood disorders. Still others speculate that sleep apnea may itself be a sign of depression. Whatever the exact connection, it is clear that treating sleep apnea can boost a patient’s mood. Researchers analyzed 19 studies of patients treated with a CPAP machine, 3 studies of patients treated with an oral splint, and 2 studies of patients treated with both. All the patients reported a significant improvement in their depression.

An oral splint is a small, mouthguard-like device that will fit over your front teeth. It will reposition your jaw, usually causing the bottom jaw to protrude slightly. In turn, this will tighten your soft tissues and keep your airways open while you sleep. We offer custom-created devices, made with great precision. Like most patients, you should find that your oral splint is quite comfortable and effective.
