40% of adults over 80 report dry mouth, dental association says
Experts link reduced saliva production to dehydration, medications, and autoimmune conditions, urging patients to consult dentists about persistent symptoms.

Dry mouth affects 40% of adults aged 80 and older, according to the American Dental Association.
The condition impacts 30% of adults aged 65 and older. Dr. Rhea Rogers, a board-certified physician, explains that dry mouth occurs when salivary glands fail to produce adequate fluid. She advises patients to identify the underlying cause as the primary step in treatment.
Rogers identifies dehydration, nerve damage, cancer, autoimmune disorders, and medications as common causes. She notes that an autoimmune disorder might indicate a larger health issue. For otherwise healthy individuals, dry mouth can serve as an early warning sign of a developing condition. "That might be their clue that you have something going on in your body. And this is your early sign," Rogers said.
Gerontologist "Sam" Cradduck emphasizes the biological importance of saliva. She compares a lack of saliva to driving a car without engine oil. Without sufficient fluid, talking, eating, and chewing become difficult. "It is the mouthwash for your body. It really is," Cradduck said. Dr. Rogers adds that saliva cleanses the mouth and protects tooth enamel. For patients with dentures, dry mouth can alter fit, complicate chewing, and lead to pain or sores.
Cradduck manages her own dry mouth, resulting from an autoimmune condition, by using stimulants. She keeps gum, candy, or hard drops in her mouth to trigger salivation. She also warns against mouthwashes containing alcohol because the ingredient dries the mouth. She advises patients to avoid drinking and smoking, which contribute to dryness. Sticky drops placed on the gums can also provide relief for some individuals.
Dr. Rogers explains that medical treatments either stimulate underproducing glands or provide moisture when glands cannot produce fluid. Patients with salivary glands removed due to cancer may use stickers around the gums to aid function. Cradduck has seen this approach help patients recover function after gland removal.
Aging expert Amy O'Rourke recommends discussing dry mouth with dentists during regular visits. Patients should mention symptoms such as frequent coughing, recurring infections, or avoiding specific foods. "Stay on top of it by reaching out to the professionals," O'Rourke said. She suggests asking dentists directly about mouth dryness every year or twice a year.
The American Dental Association data shows the prevalence of the condition among older adults. Dr. Rogers and Amy O'Rourke both stress the importance of identifying the source of low saliva production. Cradduck highlights specific behavioral changes that can alleviate symptoms. These experts provide a framework for managing a condition that affects nearly half of the oldest demographic in the United States.
