What Is Denture Stomatitis?

Denture stomatitis, also known as oral thrush or denture thrush, is a form of infection of the mouth caused by a yeast or fungus called candida. Even though everyone has candida in their mouth and it is completely normal, it will begin affecting the mouth when there is too much of it. Denture stomatitis develops due to a buildup of plaque and organic matter in the mouth that accumulates under the palate of the denture. If you wear dentures and notice they aren’t fitting well, that your mouth is sore, or the roof of your mouth feels textured, you may have denture stomatitis. Here is why it may have developed and what to do about it.

What You Need To Know About Denture Stomatitis

Those At Risk Of Developing Denture Stomatitis
This condition doesn’t happen to everyone with dentures, but the likelihood of it’s development is dependent on several factors.

  • Denture wearers are at the highest risk of developing this infection, as complete dentures cover the top palate of the mouth and partial dentures cover sections of the gums, both of which give bacteria and biomatter a place to gather. People who wear complete dentures are more likely to develop denture stomatitis than those who wear partial dentures
  • People with poor oral health are likely to develop oral thrush as this infection is largely caused by a buildup of plaque and other food particles which can be controlled with regular tooth brushing and flossing.
  • People who take steroids are also at increased risk of developing oral thrush whether their steroids are taken orally or through inhalers.
  • Some antibiotics can also cause denture stomatitis, especially when the antibiotics are taken for a long period of time.
  • Decreased immunity can also contribute to the risk of developing oral thrush, as those most likely to develop infection are young children, people over 60, or people who are immunocompromised. Suppressed or underdeveloped immune systems lead to greater risk of infections.

Signs And Symptoms Of Denture Stomatitis
Some symptoms of infection are:

  • Red, bumpy area under the denture
  • Red, sore areas at the corner of the lips
  • Creamy white lesions on the tongue, inner cheek, tonsils, throat, or roof of the mouth
  • Cracking at the corners of the mouth

Since denture stomatitis causes a the roof of the mouth to develop bumps, it can affect how a denture fits, leading to discomfort and irritation from rubbing, as well as a loose fit since complete dentures rely on the suction of the top denture to the roof of the mouth to stay in place.

Along with consulting with your doctor or dentist, there are some steps you can take to get rid of your oral thrush:

  • Maintain Good Oral Health Habits. The main form of prevention and treatment are the same: a proper oral health routine. This includes brushing and flossing any natural teeth as well as brushing the gums and tongue with a soft bristled brush. Doing this will help get rid of plaque as well as stimulate the gums. 
  • Practice Denture Hygiene. The dentures should also be cleaned nightly with denture cleaning solution and a soft bristled brush.
  • Let Your Mouth Breathe. Make sure to take your dentures out before you go to bed and leave them to soak in warm water at night. You should also take them out for a few hours during the day.
  • Take Medication. If improved oral health doesn’t get rid of the infection, there are treatments available. Most of the medication for this infection involves sucking on a specially formulated lozenge that fights infection.

Q: Is denture stomatitis contagious?
A: No, this infection does not spread from person to person.

Q: How do I know if my complete dentures fit right?
A: The easiest way to know if your complete dentures fit properly is to have the fit assessed by your denturist. A general rule of thumb for complete dentures is that the top one should suction smoothly to your gums while the bottom one should stay securely in your mouth. Your dentures should not cause sore spots in your mouth and they should not move around when you eat or speak.
