Dry mouth is common as you age—but it’s not inevitable.
According to the American Dental Association, xerostomia, or dry mouth, is a prevalent condition that can range from mild discomfort to significant oral disease affecting health, dietary intake, and quality of life. While often associated with aging, dry mouth is frequently caused by medication side effects, chemotherapy, radiation therapy for head and neck cancers, autoimmune diseases like Sjögren’s syndrome, or uncontrolled diabetes.
The Mayo Clinic notes that dry mouth occurs when salivary glands do not produce enough saliva to keep the mouth moist. This reduction in salivary flow can impair tasting, chewing, swallowing, and speaking, and increases the risk of dental caries, tooth demineralization, sensitivity, and oral infections. Saliva plays a protective role by cleansing the mouth, facilitating speech and swallowing, shielding oral tissues from physical and microbial harm, and maintaining a neutral pH.
Research indicates that approximately one in five people experience dry mouth, yet the condition remains severely under-diagnosed. Many individuals may perceive dryness even when salivary glands are functioning normally, particularly in cases involving neurological conditions such as Alzheimer’s disease, where perception of oral moisture can be altered.
Preventive and management strategies focus on identifying underlying causes, relieving discomfort, and preventing complications. The American Dental Association recommends saliva substitutes, chewing sugar-free gum to stimulate saliva flow, and maintaining good oral hygiene—such as brushing teeth gently at least twice daily with fluoridated toothpaste—to help mitigate adverse effects like cavities and periodontal infections.
Although dry mouth becomes more common with age, it is not an unavoidable consequence of aging. Addressing contributing factors such as medication review, managing chronic conditions, and using evidence-based oral care practices can significantly reduce symptoms and improve oral health outcomes in older adults.
