Find out how Dr. Han can create a customized night guard so you can sleep more soundly.

Sleep Apnea Basics

Dr. Han can often treat obstructive sleep apnea with a customized oral appliance.
Sleep apnea develops when muscles and other tissue in the back of your throat compromise the airway while you are sleeping. This is called obstructive sleep apnea. 
Obstructive sleep apnea causes your upper airway to narrow or close completely, lowering your body's oxygen level.
Your brain senses the low oxygen level and abruptly wakes you up to breathe, causing you to gasp or snort.
This can happen 30 times or more a night, disrupting your sleep and possibly the sleep of your bed partner.

Steps to Identifying Your Sleep Apnea


During your consultation, Dr. Han will discuss your symptoms and conduct an oral exam.


He will look at factors like your weight and examine your throat, tonsils, and other tissue to see if your upper airway is especially narrow. 

Sleep Study

To officially diagnose sleep apnea, Dr. Han may recommend a sleep study, which can often be done at home.


You will wear a monitoring device while you sleep that measures heart rate, blood oxygen levels, brain activity, and breathing patterns. The results will be submitted to a trusted sleep study specialist.

Oral Appliance Creation

If sleep apnea is confirmed, you will return to Dr. Han to be custom fitted with an oral appliance

How an Oral Appliance Treats Sleep Apnea

The customized night guard has springs that gently move your lower jaw forward. This opens your upper airway to allow better airflow while you sleep.

Sometimes your tongue can block the back of your throat during sleep. Your night guard can also stop that potential problem from happening.

Is Sleep Apnea Rare?

If you wake up gasping for air, you are not alone.

Other Kinds of Sleep Apnea

Besides obstructive sleep apnea, there are two other forms of sleep apnea:

Central Sleep Apnea

Central sleep apnea occurs when the muscles that control your breathing do not receive the correct signals from your brain. 

Complex Sleep Apnea

This form of apnea develops when someone suffers from a combination of obstructive sleep apnea and central sleep apnea.

Treatment Plan

If you are diagnosed with central sleep apnea or complex sleep apnea syndrome, Dr. Han may be able to refer you to a local specialist in the area.
