What Is Oral Appliance Therapy?

Some oral appliances, like the type for sleep apnea, resemble a mouth guard and are worn while you sleep. Other treatment options look more like clear trays and are worn throughout the day as well. Drs. Daniel Han, Sooyeon Ahn, and Kaylin Ju use state-of-the-art digital technology at their Leesburg and Arlington practices to customize your oral appliance and treat many kinds of oral health issues.

How a Simple Appliance Can Treat Sleep Apnea

Obstructive sleep apnea (OSA) causes gasping for air due to relaxed throat muscles or other tissue blocking your airway while you sleep. Left untreated, sleep apnea can cause daytime exhaustion as well as many physical and mental health issues. If a sleep study confirms you have sleep apnea, a customized oral appliance from our dentists can shift your lower jaw forward, opening your airway to improve oxygen flow and sleep quality.

Sleep Apnea Oral Appliance Therapy in Action

Many of our patients prefer wearing an oral appliance at night as opposed to wearing a mask connected to a continuous positive airway pressure (CPAP) machine. However, if your obstructive sleep apnea is diagnosed as severe, CPAP treatment may be best.

What Else Can Oral Appliance Therapy Treat?


Snoring is a major OSA symptom, but not everyone who snores has obstructive sleep apnea. Snoring is caused by air squeezing through relaxed throat muscles, causing them to vibrate. A customized oral appliance can open your airway, reducing muscle vibrations and improving sleep quality for you and your bed mate.


Misaligned teeth can cause chewing problems and make it more difficult to clean your teeth, along with reduced self-esteem. Our practice offers removable, clear plastic Invisalign® aligners that discreetly straighten teeth without visible metallic wires and brackets. We also offer retainers to keep your teeth from shifting back once Invisalign treatment is finished.


Bruxism, or teeth grinding and clenching, can wear down your teeth and cause jaw pain and headaches. A customized occlusal guard, such as an anterior Hawley bite plane, keeps your upper and lower teeth separated at night, eliminating friction between them. This type of night guard is also known as a deprogrammer, as it "programs" your jaw muscles to relax over time and reduce clenching.

TMJ Disorder Pain

When the temporomandibular joints that move your jaws become misaligned or inflamed, clicking sounds, lockjaw, and serious pain can occur. A customized appliance can bring these important joints back into alignment, reducing tension in tight jaw muscles. This can alleviate TMJ disorder symptoms.

Oral Appliances Can Also Protect Your Smile

Athletic activities can cause serious injuries to your or your children's teeth. Our team is skilled in creating customized sports guards. These protective appliances can prevent sports-related damage that may result in dental emergencies or costly restorative procedures.
