There are some dentists who are trained to alleviate snoring by fitting an anti snoring dental appliance. A custom dental mouthpiece to stop snoring from a dentist, along with the office visits, can cost several hundreds or even thousands of dollars, but they are usually the most effective snoring devices. Many opt for an over-the-counter mouthpiece like ZQuiet which uses the same technology as the custom device and is also FDA-cleared, but costs a fraction of the price.
