Night guards and other oral appliances have a number of different purposes. Our night guards are custom-designed by your dentist and fabricated for you by our in-house dental laboratory. We recommend night guards and oral appliances for:

TMJ Disorder

There are many potential causes of TMJ disorder, but one of the most common is nighttime teeth grinding and jaw clenching. Many patients are unaware of these habits because they occur when they sleep, but the result is overactive jaw muscles that cause headaches, jaw pain, and facial pain. By preventing teeth grinding and jaw clenching, a night guard can relieve TMJ disorder.


Some patients may not have TMJ disorder, but they still grind their teeth or clench their jaws at night. This bruxism can result in broken teeth, compromised dental restorations, and worn down teeth that are sensitive, painful, and have a uniform, flat appearance. A night guard provides protection for your teeth by physically preventing you from clenching and grinding.

Sleep Apnea

Dentists are trained to diagnose and treat sleep apnea. Often, a simple oral appliance can prevent the need for a CPAP machine. These appliances reposition the lower jaw while you sleep to keep the airway open and unobstructed, helping you get a better night’s rest.


The same oral appliance therapy used to relieve sleep apnea symptoms can also be used to help you stop snoring.

Frequently Asked Questions About Night Guards

Do night guards really work?

Yes, night guards are an effective solution for bruxism because they provide a barrier of protection between your teeth. 

Do night guards hurt at first?

It’s common to feel that your night guard is uncomfortable when you first start using it. It’s rare that it would be described as painful, but you may experience tightness or soreness the first few nights you use it. As you get used to it, it should start feeling more comfortable. If it doesn’t, let us know so we can see if it needs to be adjusted.

What does a night guard do at night?

A night guard prevents bruxism, or teeth grinding and jaw clenching. 

Do night guards help TMJ?

If your TMJ symptoms are caused by jaw clenching and teeth grinding, a night guard can help you find relief. If, on the other hand, your TMJ disorder is caused by an injury to the joint or arthritis, a night guard will not alleviate your symptoms.

How does oral appliance therapy work?

Oral appliance therapy for snoring and sleep apnea works by repositioning the lower jaw while you sleep, which keeps the soft tissues engaged so the airway remains open and unobstructed.
