Many people with denture stomatitis only find out because their dentist mentions it. The gum or palate under the denture turns red and sometimes swollen, often with small red dots, yet it frequently causes no pain at all. It is one of the most common problems in denture wearers, and in most cases it improves once the denture comes out at night and is cleaned properly every day.
How common it is
A 2024 systematic review by Perić and colleagues in the Journal of Fungi reported that denture stomatitis affects between 20 and 67 per cent of people wearing removable dentures around the world. It is seen with both full and partial dentures.
Yeast, habits and fit all play a part
The condition is usually linked to Candida, a yeast that lives harmlessly in many mouths. Under a denture, especially one worn day and night, the yeast and bacteria form a film on the fitting surface that sits against the gum, and the tissue reacts with redness and inflammation.
The same review identified the type of denture, continuous wearing and a Candida film encouraged by poor hygiene as the main causes. DermNet, the dermatology reference, lists further risk factors including diabetes, dry mouth, a full upper denture, and an old or poorly fitting denture. A smaller number of cases relate to rubbing from the denture or, rarely, an allergic reaction to the material.
Nights without the denture make the biggest difference
DermNet describes removing and cleaning the denture daily, and especially taking it out at night, as the most important step in treatment. Leaving the tissue uncovered overnight lets it recover and removes the warm, enclosed space the yeast prefers.
A practical routine looks like this:
- Rinse the denture after meals when you can.
- Brush it every day, paying most attention to the side that touches your gum, using a soft brush and mild soap or a denture cleaner rather than toothpaste.
- Soak it in a denture cleaning solution and leave it out overnight, stored as your dentist advises.
- Brush your gums, tongue and palate gently each day, and keep any natural teeth clean.
Our article on denture cleaning tablets, soaks and brushing covers what the evidence says about each step.
When better habits are not enough
If redness persists despite a good routine, your dentist or doctor may suggest an antifungal medicine applied to the mouth and the denture. A 2016 systematic review by Hilgert and colleagues in the Journal of the American Geriatrics Society found that both an antifungal treatment and denture disinfection reduced signs of stomatitis compared with inactive treatments, although most of the trials had a high risk of bias. If you take blood-thinning medicine, tell your dentist or doctor before using any antifungal gel, as some interact with it.
The denture itself also matters. An old or poorly fitting denture traps debris and irritates the tissue, and it may need a reline or replacement. Our guide to denture care and relines explains how that works. Managing a dry mouth or diabetes with your doctor can help stop the condition returning.
Red patches that need a closer look
Denture stomatitis is not dangerous in itself, but red or sore areas in the mouth can occasionally be something else. See a dentist if a red area or sore under your denture has not settled within two to three weeks of improving your routine, or sooner if there is pain, bleeding, a white or red patch, or a denture that has started to rock.
What it may cost to sort out
Treatment is often modest: a denture review, advice, and sometimes an antifungal or a reline. As a general Australian market guide, a denture reline commonly costs about $300 to $600. This is a typical market range, not a Lumi fee. See our current offers or book a general dental appointment for an assessment.
What patients ask about denture stomatitis
Can I keep wearing my denture during the day?
Usually, yes. The key changes are taking it out overnight and cleaning it thoroughly every day. Your dentist will also check how it fits.
Why does it keep coming back?
Common reasons are wearing the denture overnight, a cleaning routine that misses the fitting surface, a denture that no longer fits, or a dry mouth. Addressing those usually helps.
Would implants help?
Implant-retained dentures still need thorough daily cleaning, but for some people a more stable denture is easier to wear and look after. Our guide to implant-retained overdentures explains the option, and our comparison of full and partial dentures may also help.
Having the redness checked
If the tissue under your denture is red or sore, our dentists can examine it, check the fit and suggest a plan to settle it at our Melrose Park practice. If you use adhesive, our article on denture adhesives explains how to clean it off properly each day.
