Dry Mouth, Big Problem: What Your Mouth Is Trying To Tell You

Imagine waking up in the middle of the night with your mouth feeling like sandpaper, swallowing is difficult, speaking is uncomfortable, and even breathing feels strange.

For many, this isn’t just an occasional inconvenience, but a chronic condition known as dry mouth, or xerostomia. Though often overlooked, this seemingly minor issue can have a major impact on daily life, oral health, and even nutrition.

Dry mouth occurs when the salivary glands fail to produce enough saliva to keep the mouth adequately moist. Saliva is essential because it helps break down food, neutralise acids, prevent tooth decay, and keeps the delicate tissues of the mouth lubricated and protected.

Without enough of it, people may struggle to chew or swallow, face a heightened risk of cavities and gum disease, and become more vulnerable to oral infections.

Dry mouth can be caused by a variety of factors, including medications, dehydration, smoking, autoimmune diseases like Sjögren’s syndrome, and even stress. More than 400 medications list dry mouth as a side effect , including antihistamines, antidepressants, and blood pressure drugs , making it a common complaint among older adults. It can also be a side effect of cancer treatments such as chemotherapy and radiation, especially when directed at the head or neck.
