Denture Stomatitis: Everything you Should Know About its Causes and Prevention

Denture-related stomatitis (oral stomatitis) is a condition that commonly affects denture wearers. In fact, studies have shown that up to 70% of denture wearers are affected by the condition, with complete (full) denture wearers being more likely to develop the condition than partial denture wearers. But what exactly is denture stomatitis, and how can denture wearers prevent it? Keep reading to find out.

What is Denture Stomatitis?

Denture stomatitis is a condition that leads to excessive pain, inflammation, redness and irritation in the mouth. For a denture wearer, the condition can make eating, speaking and even sleeping inconvenient.

What are the main causes?

Denture stomatitis is primarily caused by the build-up of Candida, which is a naturally occurring yeast (fungus) in the mouth. This candida build-up can then lead to inflammation and gum infection, thus, making dentures sore and uncomfortable (even painful) to wear. 

Some of the other factors that can lead to the development of denture stomatitis include; ill-fitting dentures, poor oral hygiene, wearing dentures to sleep, smoking, a high sugar and carbohydrate diet, endocrine dysfunction, alcohol use and immunosuppression.

What are the main symptoms Denture Stomatitis 

The symptoms may vary from mild irritations (which can normally be fixed with a simple denture reline or adjustment from a reliable denture repair company) to serious symptoms such as canker sores, xerostomia (dry mouth), bad breath, difficulty swallowing, swollen, red and bloody gum tissue and irritation of the gums under the dentures.


Like most oral health complications, denture stomatitis can be easily prevented with the right type of oral hygiene, denture care, and maintenance. Some of the ways you can prevent denture Stomatitis include;

Choosing the Right Denture 

Having dentures that are right and properly fitted is one of the best ways to prevent denture stomatitis. This is because properly fitting dentures will remain stable and in position, so you won’t have to deal with the pain and discomfort associated with shifting. There will also be no room for yeast and bacteria to build up and cause irritations or infections. 

Removing Your Dentures Every Night 

Wearing your dentures to sleep is never a good idea. Apart from your gums and jaws needing to breathe and recover, taking out your dentures and soaking them every night ensures that they stay clean and there is no build-up of bacteria or yeast. Making a habit of removing your dentures every night will help you prevent denture stomatitis and also ensure that your gums have enough time to recover after holding your dentures in place throughout the day.

Clean Your Dentures Regularly 

As mentioned earlier, a build-up of bacteria in your dentures can lead to gum irritation, inflammation, and infection. To prevent this from happening, your dentures need to be cleaned properly and on a regular basis. Make sure to rinse them after every meal and thoroughly clean them at the end of each day with a denture-specific cleaning product and a soft-bristled toothbrush.


Denture stomatitis is a common condition that affects denture wearers. The condition can make it difficult for patients to chew, sleep and speak comfortably. Luckily, you can easily prevent denture stomatitis by wearing properly fitting dentures, and maintaining good oral hygiene and denture care.
