Causes of dry mouth

Dry mouth can affect everyday comfort and can lead to more serious oral health concerns. This video explains some of the possible causes, helping you recognise what might be contributing to the problem.

Have a look at this video to help identify signs of dry mouth.

What Causes Dry Mouth?

Medications

Side effect of medicines, such as antihistamines, antidepressants, diuretics and certain blood pressure tablets.

Medical Conditions

Including diabetes, stroke, Parkinson’s disease and Sjögren’s syndrome.

Nerve Damage

Nerve damage from injury or surgery affecting the head or neck can reduce saliva production.

Cancer Treatments

Cancer treatments like radiation therapy and chemotherapy can change how much saliva the salivary glands produce.

Acid Reflux

Frequent acid reflux can lead to dryness.

Mouth Breathing

Breathing through the mouth, especially at night.

Dehydration

This may result from not drinking enough fluids, having a fever, sweating excessively, vomiting, diarrhoea or losing blood.

Lifestyle Factors

Smoking, drinking alcohol and eating heavily spiced foods can increase dryness.

Environmental Factors

Environmental conditions, including dry weather and air‑conditioned rooms, can make symptoms worse.

Age‑Related Vulnerability

Older adults are more likely to experience dry mouth because they often take multiple medications and may be more vulnerable to reduced saliva production.

Dryness or pain in the mouth may be an early warning sign of an oral health issue that needs attention.

We encourage you to seek advice from a GP, dentist or another healthcare professional if you notice any changes in your own oral health, or in the oral health of the person you care for, or if you have concerns about mouth discomfort, dry mouth or swallowing difficulties.
