Sleep apnea is a condition that arises when the muscles of the tongue and throat constrict airways during sleep. This can cause snoring, trouble breathing, and even death. There are a few different treatment options available to sufferers of sleep apnea. The most common are CPAP and a dental appliance or mouth guard. A CPAP machine consists of a facemask, hose, and motor. The motor blows air through the hose and facemask to provide constant air pressure in order to keep airways open. There are certainly benefits to using a CPAP machine, but they are not for everyone. The noise of the machines can disturb your partner, the mask can be uncomfortable to wear, and the cost of a CPAP machine can be out of range for some people. The other most commonly used treatment for sleep apnea is a dental appliance or mouth guard. The sleep apnea dental appliance can hold the jaw, teeth, and tongue in position in a way that can improve airflow without the need of a noisy machine or facemask. There are more than 100 different types of sleep apnea appliances that your dentist may offer.
