Also known as xerostomia, dry mouth can cause uncomfortable symptoms besides thirst, including cracked lips, mouth sores, bad breath, and dry nasal passages. While the condition usually results from medications, medical procedures, or disease, lifestyle can also exacerbate dry mouth by practices that decrease saliva production. To combat dry mouth, individuals should stay hydrated with roughly 64 ounces of water a day and limit the intake of alcohol and caffeine, which are diuretics.
Because most brands of mouthwash contain alcohol, they can increase dry mouth symptoms. Chewing on mint or parsley and snacking on water-rich vegetables can naturally freshen breath and stimulate saliva glands. Focusing on nose breathing during the day will train the body to do the same at night. Mouth breathing at night is a key factor in dry mouth. Finally, brushing with fluoride toothpaste and flossing daily can help maintain a healthy oral environment.
