Xerostomia, also known as dry mouth syndrome, is a medical condition caused by a decrease in saliva production. This can lead to various symptoms such as dry mouth and throat, difficulty speaking and swallowing, bad breath, and an increased risk of cavities and other oral health problems. Xerostomia can be caused by various factors, including medications, medical conditions, cancer therapy, nerve damage, tobacco and alcohol use, recreational drug use, and dehydration. To relieve dry mouth symptoms, individuals should take care of their mouth and use a good quality natural toothpaste with xylitol. Treatment for xerostomia involves managing symptoms, such as brushing teeth and gums gently, avoiding mouth rinses with alcohol, using artificial saliva, and avoiding caffeinated beverages, tobacco, and alcohol. Xylitol, a healthier substitute for sugar, can help stimulate saliva production, maintain oral hydration, wash away harmful bacteria, and reduce the growth of bacteria that cause tooth decay.
