If the roof of your mouth or the gum under your denture looks red and feels sore, you are far from alone. Denture stomatitis, inflammation of the tissue covered by a removable denture, affects somewhere between 20 and 67 percent of denture wearers, and it is most common in older adults. It is usually painless, which is why many people do not realise they have it, and it is very treatable once the causes are addressed.
Key takeaways
- Denture stomatitis is red, inflamed tissue under a denture, affecting 20 to 67 percent of wearers, often with no pain.
- The main drivers are wearing the denture day and night, poor denture cleaning, and an overgrowth of a yeast called Candida.
- The single most effective change is taking the denture out overnight and cleaning it properly every day.
- It is treatable; persistent cases may need an antifungal from your dentist or doctor and a denture that fits well.
- Any red or sore patch that does not settle in two weeks should be checked, to be sure it is nothing more.
The one rule that fixes most cases: take the denture out at night
If there is one habit that clears and prevents denture stomatitis, it is leaving the denture out while you sleep. Wearing a denture continuously, day and night, is one of the strongest risk factors, because it keeps the tissue covered, warm and moist, which is exactly what the Candida yeast needs to overgrow. Giving the tissue several hours uncovered each night, combined with daily cleaning, removes that environment and lets the gum recover. Store the denture in water or a denture-soak solution overnight, not dry.
What causes it
Candida overgrowth
A yeast called Candida, most often Candida albicans, lives harmlessly in many mouths. Under a denture it can overgrow and inflame the tissue. This is why the condition is also called Candida-associated denture stomatitis.
Wearing and cleaning habits
Continuous wear and inadequate cleaning are the biggest behavioural causes. Plaque and yeast build up on the fitting surface of the denture and sit against the gum all day and night.
Denture fit and other factors
An ill-fitting or old denture traps debris and irritates the tissue. Dry mouth, smoking, a high-sugar diet, diabetes, and a weakened immune system all make it more likely.
How it is treated
Treatment combines better habits with addressing the yeast and the denture. The foundations are taking the denture out overnight, cleaning it daily by brushing the fitting surface with soap or a denture cleaner and soaking it, and keeping the mouth and any remaining teeth clean. For persistent or more severe cases, your dentist or doctor may prescribe a topical antifungal, and a poorly fitting denture may need a reline or remake. If you have diabetes or a dry mouth, managing those helps prevent it returning.
A simple daily denture routine
- Remove and rinse the denture after meals.
- Brush the denture, especially the side that touches the gum, with a denture brush and mild soap or denture paste, not abrasive toothpaste.
- Take it out overnight and soak it in water or a cleaning solution.
- Brush your gums, tongue and palate gently each day.
- See your dentist if redness, soreness or a poor fit persists.
When to get it checked
Denture stomatitis itself is benign, but a red or sore patch in the mouth can occasionally be something else, so anything that does not settle within two weeks of improving your routine deserves a look. See a dentist sooner if there is pain, bleeding, a white or red patch that wipes or does not wipe away, or a denture that has become loose or rocks.
The cost angle
Sorting out denture stomatitis is usually inexpensive, often just a denture review, advice, and possibly an antifungal or a reline. As a general market guide only, a denture reline commonly ranges from around 300 to 600 dollars. These are general ranges, not a quote, and the team at Lumi Dental does not list its own prices here.

Frequently asked questions
Is denture stomatitis a fungal infection?
Usually, yes. It is most often linked to an overgrowth of Candida yeast under the denture, combined with continuous wear and poor cleaning.
How do I get rid of the redness under my denture?
Take the denture out overnight, clean it thoroughly every day, keep your mouth clean, and see your dentist. Persistent cases may need an antifungal and a denture check.
Is it contagious?
No. It is an overgrowth of yeast already present in your own mouth, not something you catch from others.
Can I still wear my denture?
Yes, during the day, but the key change is taking it out at night and cleaning it well. Your dentist will check the fit.
Why does it keep coming back?
Usually because the denture is worn overnight, not cleaned thoroughly, or no longer fits well, or because of dry mouth or diabetes. Addressing those stops it recurring.
If the tissue under your denture is red or sore, the team at Lumi Dental in Melrose Park can check the fit and help clear it up. Related reading: denture care and relines, full vs partial dentures, denture adhesives, and implant-retained overdentures.
