Dry mouth: what helps day to day and what matters at your appointment

01 A dry sensation and too little saliva are not exactly the same

The term xerostomia initially describes the subjective feeling of a dry mouth. This does not always coincide with a measurably reduced amount of saliva. “Not drinking enough” is therefore not an adequate explanation in every case. The course of the problem, associated circumstances, an examination and, where necessary, further assessment are what matter. American Dental Association: Xerostomia

It also helps to explain what specifically affects you. Is dryness mainly a problem at night? Do you need a drink to help with eating? Does it interrupt longer conversations? These observations make your symptoms understandable without you having to identify the cause yourself first.

02 What could cause it?

Insufficient fluid intake, breathing through the mouth at night or stress may accompany a dry mouth. Medication and medical conditions are also possible triggers. A link in timing with a new tablet or a changed dose is therefore important information. Please do not stop prescribed medication on your own. NHS: Dry Mouth

Persistent dry mouth is also not an inevitable consequence of ageing. However, people tend to take more medicines as they get older, and these may affect saliva flow. Their role in an individual case can only be assessed in the context of the overall situation. NIDCR: Dry Mouth

03 Three everyday options

1. Keep water to hand. Small sips of water may ease the dry sensation. Sugar-free chewing gum may stimulate saliva flow. Very acidic or sugary sweets are not a good long-term solution. NHS: Dry Mouth

2. Continue careful tooth care. Reduced saliva flow may increase the risk of decay. Regular brushing with fluoride toothpaste therefore remains important. Which additional measures are suitable depends on the findings; they do not replace investigating the cause. American Dental Association: Xerostomia

3. Choose aids carefully. Pharmacies offer moisturising gels or sprays, for example. Not every product suits every situation. Ask for advice, especially if symptoms persist or the lining of your mouth is sensitive. NHS: Dry Mouth

04 What you can bring to the appointment

An up-to-date list of all medicines and over-the-counter products helps with assessment. Information about when the problem started, the time of day and products already tried is also useful. If needed, saliva flow and the oral lining are examined more closely. American Dental Association: Xerostomia

A brief note may be enough: “For about four weeks, mainly at night; I have tried this spray.” There is no need for a detailed diary. What matters is discussing the symptoms rather than simply masking them with ever more products.

If your mouth stays dry for weeks, is painful or eating and speaking become difficult, have the symptoms assessed by a doctor or dentist. NHS: Dry Mouth
