Why they work: These plastic-based mouthpieces clip onto your teeth and move the jaw forward to keep the soft tissue in the back of the throat from blocking the airway. Available by prescription from some dentists, the custom-made pieces are less than three millimeters thick and have “an 80 percent success rate and last five to six years,” says Gail Demko, a dentist specializing in dental sleep medicine in Weston, Massachusetts. But they’re also pricey ($1,500 and up).
Good to know: This solution is ideal for snoring caused by mild to moderate sleep apnea, a condition in which your airway becomes completely blocked during sleep, with the result that you not only snore but also stop breathing for up to 10 seconds. Only a sleep specialist can determine if you have sleep apnea, but if you do, medical insurance may cover the cost of the device.
