ZQuiet Advance comes pre-assembled and takes less than 5 minutes to mold to your teeth. The mouthpiece comes with detailed instructions and the process is easy as detailed in this section of the instructional video (WATCH VIDEO)

The mouthpiece is made of 3 different types of medical-grade plastic that is specially formulated for medical devices and has passed stringent biocompatibility testing to ensure it is safe for intraoral use.

It depends on the individual, but many customers find that their mouthpiece lasts for many months of nightly use. Just like a toothbrush, we recommend replacing ZQuiet Advance at least every 6 months, or if it is excessively worn or shows any signs of damage.

Both the Comfort and Advance mouthpieces share many similar traits. They are both FDA Cleared, safe and effective, made with medical grade materials, are thin and low-profile, and have a hinged design that allows natural jaw movement.

The differences are that the Advance is moldable and has 4 levels of jaw advancement adjustment and works with straight or crooked teeth, where the Comfort mouthpiece is ready-to-use out of the box and comes in 2 jaw advancement sizes and works best with straight front teeth.

You should expect to see results the very first night you use it. Optimal results occur after determining which jaw advancement strap size works best for you. 

Once you have determined the correct strap size to use, you should remove and replace each strap on one side at a time. To remove the strap, you must position the strap so that the strap slots align with the post keys before it can be removed. Once both ends of the strap are removed, attach the new strap by aligning the strap hole and slots over the post key one end at a time. This process should be repeated for replacing the strap on the opposite side. Please see the instructions for illustrations and guidance or in this section of the instructional video (WATCH VIDEO)
