A persistently dry mouth can make wearing dentures less comfortable and can affect eating or speaking. The cause deserves attention as well as the appliance. Adding adhesive or repeatedly altering a denture may not address the problem if dryness is part of the picture.
Describe the pattern
Tell your clinician whether the dryness is constant, mainly at night or linked to a change in medicines or health. Mention soreness, changes in taste and difficulty swallowing food. Bring a medication list. Dry mouth has several possible causes; do not assume it is simply an unavoidable part of ageing.
Make small, sensible changes
Regular sips of water may help, within any fluid advice you have been given for another condition. A pharmacist can advise on suitable saliva-support products. Not every gel, spray or lozenge suits every person, especially if you have natural teeth or swallowing difficulties. Avoid choosing a product only because it promises moisture.
Review the denture and the mouth
Ask the dental team to assess fit, tissue health and your cleaning routine together. Continue the advised overnight break and denture care. If natural teeth remain, discuss protection against decay. Do not stop a prescribed medicine yourself even if its leaflet mentions dry mouth.
Know when to seek further help
See a GP if dryness persists despite simple measures, interferes with eating or talking, or comes with other symptoms. A painful, swollen or bleeding mouth, white patches or difficulty swallowing should also be reported. Your dentist, GP and pharmacist may each have a different part to play in making the routine more comfortable.
