A self-adhering, slowly dissolving disk that releases xylitol, cellulose gum, and mild mint flavor has been found to be effective in relieving dry mouth during prolonged periods of sleep, according to a small study in the International Journal of Dental Hygiene (October 31, 2011).
Dry mouth is worst while sleeping, when saliva flow is lowest for everyone, and this can disturb sleep, according to Dr. Burgess. It can also cause an increase in levels of bacteria that cause caries, periodontal disease, and halitosis.
“When the subjects in this study used two XyliMelts disks while sleeping, they reported their mouths were more moist upon waking in the morning, showing that the product reduces the sensation of dryness all night long,” Dr. Burgess said. “They also reported that the flavors of xylitol and mint were still present in their mouths upon waking in the morning, showing that the time-release aspect of the product worked all night long.”
