To measure the effect of the DryMouth Shield on snoring.

The primary outcome of this study is to aid in the final design of the DryMouth Shield and to assess the effect of the DryMouth Shield on snoring frequency. To accomplish this we will compare the frequency of snores during 1) overnight polysomnography without using the DryMouth Shield and 2) overnight polysomnography using the DryMouth Shield. Secondary outcomes of the study will include: 1) compare the difference in the volume of snores without and with the use of the DryMouth Shield; 2) estimate the changes in apnea hypopnea index without and with the use of the DryMouth Shield; 3) describe symptoms of dry mouth without and with the use of the DryMouth Shield 4) describe symptoms of bruxism without and with the use of the dry mouth shield and 5) gather patient feedback about the user experience with the dry mouth shield.
