A standard nightguard is designed to prevent tooth damage when grinding or clenching. It is not designed to treat sleep apnea and will not reduce airway obstruction during sleep. However, it’s worth understanding the relationship between night guards and sleep apnea in more detail.
The Purpose of a Nightguard
A nightguard protects teeth from the wear caused by grinding and clenching during sleep. It acts as a barrier that sits between your upper and lower teeth when grinding. It does not move the jaw or open the airway.
Nightguards vs. Oral Sleep Apnea Appliances
Both devices are designed to be worn in the mouth during sleep, and both are custom-fitted by a dentist. The difference is in what they do. A sleep apnea oral appliance is specifically designed to move the lower jaw forward and keep the airway open. A nightguard does not do this.
The Confusion Between Nightguards and Sleep Apnea Appliances
Many patients who grind their teeth also have undiagnosed sleep apnea. Grinding is sometimes the body's response to restricted breathing, and often involves moving the jaw and tightening muscles to reopen the airway.
What Clarkson Dental Group Recommends
If you have been diagnosed with sleep apnea, a custom oral appliance is the appropriate dental treatment, not a standard nightguard. If you grind your teeth and are not sure whether it’s related to sleep apnea, your Chesterfield, MO, dentist can help assess your situation and refer you for a sleep study if needed.
