Turning on a humidifier in the bedroom at night and using saliva-friendly toothpaste and mouthwash just before bed are two ways to combat dry mouth while sleeping, according to the Mayo Clinic. Saliva is crucial for the long-term health of the mouth and teeth, so treatment is a necessity.
Dry mouth, also known as xerostomia, can stem from a number of different causes. The best remedies to use at night increase the humidity of one's surroundings and boost saliva production in the mouth. Mouthwash made with xylitol serves as a saliva substitute, so choosing Mouth Kote, Oasis Moisturizing Mouth Spray or Biotene Oral Balance are all helpful choices. Chewing sugar-free gum or candies with xylitol introduces it into the system, while also stimulating the production of saliva. Brushing with a toothpaste that contains fluoride, or even a prescription fluoride toothpaste, protects oral health overnight, as stated by Mayo Clinic.
There are other strategies for fighting dry mouth during the day, according to the Mayo Clinic. One should avoid mouthwash with alcohol, as the alcohol is often a drying agent. Caffeine should be avoided because it can dry out the mouth. Instead, it is important to sip on water throughout the day. Breathing through the nose rather than the mouth is another way to keep the mouth as damp as possible.
