Stick it to dry mouth with Oracoat XyliMelts dry mouth relief moisturizing discs - oral-adhering discs that stick to your teeth or gums to help relieve persistent dry mouth symptoms. XyliMelts discs are made with Xylitol, a natural, sugar-free sweetener that helps increase saliva flow. Using adhering disc technology, they gradually release 550 mg of xylitol, providing continuous effectiveness, especially overnight when saliva flow is at its lowest. These dry mouth relief moisturizing discs may be used day or night and last 1-4 hours during the day and 4-8 hours at night, depending on saliva production (individual results may vary). The discs are specifically formulated to neutralize mouth acids, and are pH buffered to the best range for the mouth, pH 8. Oracoat XyliMelts soothing dry mouth relief disc is vegan, sugar-free and preservative-free. It contains no animal products, corn, protein, color or preservatives, nuts, wheat, gluten, soy, egg or yeast. The OraCoat brand represents a family of products that solve oral care problems by coating the mouth with ingredients that become active when they are slowly released. OraCoat's innovative oral care solutions are backed by careful research based on medical science to ensure optimum performance and user safety
