One of the treatments provided by our dentist for sleep apnea is the MicrO2® sleep device. The MicrO2 device is a comfortable, easy-to-use dental device to alleviate snoring and other symptoms of obstructive sleep apnea and help you rest better. We invite you to contact RK Dentistry at 925-736-4201 to learn more about the MicrO2 device in Danville, California, and to schedule your consultation with Dr. Richard J. Koeltl.

If you have been diagnosed with obstructive sleep apnea, our dentist can provide the MicrO2® device to help you rest better at night and enjoy better overall health. The MicrO2 device is the smallest and most comfortable custom-made lower jaw advancement device available. It is used to offer greater tongue space, and works by holding your lower jaw in a slightly forward position. This moves the throat tissues away from the back of your throat, opening your airways to reduce snoring and obstructive sleep apnea.

Only a dentist can provide you with a MicrO2 device. When this course of treatment has been decided, our dentist will take molds of your teeth, and will measure and record a bite registration with your lower jaw in a forward position. The mold and records will then be send to a lab to be fabricated. When completed, our dentist will examine your MicrO2 device to ensure a perfect fit, and provide you with instructions on how to insert, remove, clean, and care for your device.

Each MicrO2 device is custom-made to provide a perfect fit. There are two parts to your appliance. One part first over your upper teeth, and the other fits over your lower teeth. There will also be a series of additional upper or lower devices to help place your lower jaw in the most effective position. The MicrO2 device may seem complicated at first glance, but is actually extremely easy to use, featuring an adjustment method similar to changing aligners.
