Xerostomia: A Neglected Burden in Oral Health

Written by : Dr. Rockson Samuel

Xerostomia (the subjective feeling of dry mouth) arises from reduced or absent saliva flow. It is very common – population studies report prevalence anywhere from ~20% up to 50% or more in older groups – yet it is often overlooked. Patients may experience burning mouth, altered taste, difficulty chewing or swallowing, and oral soreness, but because xerostomia is a symptom rather than a disease, it has historically received too little attention in healthcare. Indeed, oral medicine experts have long warned that “oral health has been described as a neglected area of health management” and that patients with dry mouth often feel their concerns are disregarded. This review highlights how xerostomia affects diverse groups (especially the elderly, oncology patients, and those on chronic medications), examines why it is under-recognized, and underscores the critical role dentists must play in early detection, diagnosis, and management of this condition.
