Dry mouth, or xerostomia, occurs when your mouth isn’t producing enough saliva to keep itself moist. Saliva is necessary to protect your mouth from infection, keep it clean and neutralize acids to help prevent plaque buildup and tooth decay. It’s very common and affects about 20% of people worldwide. Dry mouth can have a significant impact on your health and overall quality of life. It can result in tooth decay, disrupted sleep, a rough, dry tongue, bad breath, difficulty chewing and swallowing, sore cracked lips, dehydration and more. What makes XyliMelts so effective against dry mouth? The key ingredient is xylitol, a naturally sweet carbohydrate found in raspberries, corn, oats, and other plants. Xylitol cannot be digested by the harmful mouth bacteria that cause tooth decay, gum disease, and infections. Plus, when xylitol lingers in the mouth, it stimulates saliva and may reduce the risk of tooth decay. Clinical studies suggest that you can maximize the benefits of xylitol by slowly releasing a continuous concentration of xylitol in your mouth. XyliMelts help solve this problem by utilizing adhering disc technology that releases just the right concentration of xylitol over time—meaning hours of dry mouth relief for you as the disc coats, moisturizes, and increases saliva flow, especially while sleeping when dry mouth is worst. There are several causes of dry mouth and bad breath including, but not limited to: Daily use of medications that cause dry mouth, Cancer treatment, Poor dental health, Illness, disease and their associated medications, Infections of the mouth and respiratory system, External agents, such as food or tobaccos. One of the most common causes of dry mouth and bad breath may be a side effect of taking medication for a variety of conditions.
