XyliMelts are oral-adhering discs that stick to your teeth or gums to relieve persistent dry mouth. Use XyliMelts during the day or while sleeping and find temporary relief from frequent thirst, sticky dryness in the mouth and throat, and other unpleasant dry mouth symptoms. Made with xylitol, a natural sweetener that helps stimulate saliva flow, XyliMelts utilize adhering disc technology to slowly release 550 mg of xylitol, which is most effective when continuously released and lingers in the mouth, especially when used while sleeping when saliva flow is lowest. XyliMelts last for hours, moisturizing and coating the mouth for optimal comfort. The mild mint flavor freshens your breath and the xylitol may reduce the risk of tooth decay.
