Dry mouth might sound like a minor inconvenience, but it can have a big impact on your oral health and daily comfort.

Dry mouth might sound like a minor inconvenience, but it can have a big impact on your oral health and daily comfort. If your mouth often feels sticky, dry, or uncomfortable, you may be experiencing a condition known as xerostomia. Let’s explore what causes it, how to recognise it, and what you can do about it.
Dry mouth occurs when your salivary glands do not produce enough saliva. Saliva plays a vital role in keeping your mouth healthy. It helps wash away food particles, neutralises acids, and protects against tooth decay and gum disease.
It also lubricates your mouth, making it easier to chew, swallow, and speak comfortably—something we often take for granted until it’s missing.
Without enough saliva, your mouth becomes more vulnerable to problems—and yes, it can make eating a biscuit feel like chewing cardboard.
Many prescription and over-the-counter medications can reduce saliva production. These include antihistamines, antidepressants, and blood pressure medications.
Not drinking enough water can quickly lead to a dry mouth. Simple, but often overlooked.
Conditions such as diabetes, Sjögren’s syndrome, or certain autoimmune disorders can affect saliva production.
Smoking, alcohol, and excessive caffeine intake can all contribute to dryness.
Cancer treatments can significantly affect saliva production. Radiotherapy to the head and neck can damage salivary glands directly. However, chemotherapy and immunotherapy can also contribute to dry mouth by altering how your body produces saliva or affecting the oral tissues.

Adjust Your Diet
Limit caffeine, alcohol, and sugary foods. Choose moist, easy-to-chew foods instead.
Use Saliva Substitutes
Over-the-counter sprays and gels can provide relief, especially at night.
Maintain Excellent Oral Hygiene
