Zyppah utilizes a boil-and-bite fitting method that is very similar to other mandibular advancement devices (MADs). However, while other anti snoring devices generally have a recessed tray that guides your teeth in place, Zyppah does not. For this reason, you need to be a little more careful during the fitting process. You will definitely want to have a mirror handy.
In addition to a mirror, you might as well also grab a small pot, bowl or mug, pair of tongs, and a stopwatch. Before putting the Zyppah in your mouth it is a good idea to clean it with warm water first. Examine the device, and make sure you can identify the top and bottom trays. You will see the word “Zyppah” on the lower tray. You will also notice that the lower tray is already pulled slightly forward. Once you are comfortable with this, you can move onto the fitting. You do not want to wait until the appliance is hot and soft to try to figure out how it goes in your mouth.
Begin by bringing a pot of water to boil. In the meantime put ice water in the small bowl or mug. You can even toss an ice-cube in there just to make sure it does not acclimate to room temperature.
When the water boils, remove it from the heat. Use the tongs to hold the device, and submerge completely for 60 seconds. After removing from the hot water give it just a few seconds to cool off, so you don’t burn your mouth. Be very gentle with it because at this time it is now soft, sticky, and pliable. If you are going to use your hands then hold it by the rubber strap or hard tray.
Looking in the mirror, place Zyppah in your mouth, starting with your lower jaw. Your bottom teeth should touch the point where the hard black plastic touches the green thermoplastic. When your teeth are properly positioned extend your lower jaw forward. Gently place your upper teeth at the inside point of the hard plastic. When you are confident that your teeth are in the best position, bite down into the device for a full minute.
Slowly remove the device and submerge it in the ice water to harden. Once your Zyppah has cooled completely try wearing it. If you don’t feel that the fit is correct, repeat the process again. You can usually fit an MAD around three times before you start to compromise the material. Overall I like the mouthpiece, but learn more about my Zyppah complaints and be sure to compare after reading our SnoreRx review.
