If you wear dentures, you likely understand how important it is that they fit properly. That’s because when they don’t, it can be very hard to use them. Worse yet, in addition to being very difficult to eat, speak, and smile with them, it can also cause painful irritation and sores that leave your gums vulnerable to infection and inflammation. It can even increase your risk of oral cancer, which if left untreated, could cost you your life. Here’s why it’s so important to ensure that your dentures fit well, and when it’s time to see your dentist if they don’t.

How Improper Denture Fit Can Cause Oral Cancer

While it may seem strange that a badly fitting prosthetic could increase your risk of oral cancer, there are several ways this can occur, including:

  • Inflammation due to constant friction, which can eventually lead to cell damage.
  • Chronic irritation from rubbing against your soft tissues.
  • Cellular damage and mutation from persistent inflammation.

Furthermore, if you have any other risk factors for oral cancer such as smoking or drinking alcohol, improperly fitting dentures can increase your already elevated risk.

Signs Your Dentures May Need Repair

If you notice any changes in the fit, functionality, or appearance of your dentures, there’s a good chance it’s time to bring them to your dentist for an evaluation. Here are a few warning signs to look out for:

  • Broken teeth.
  • Chips or cracks in the teeth or the base.
  • Difficulty chewing with them.
  • Discomfort while wearing them.
  • Changes in your facial shape.
  • Changes in the fit of your dentures.
  • Pressure sores and oral sores.
  • Gum irritation.
  • Changes to speech patterns.
  • Stains or foul odors on the prosthetics.

How to Reduce Your Risk of Oral Cancer with Dentures

Although preventing oral cancer completely may not be within your power, it is possible to reduce your risk of developing it. Here are some useful steps you can take to assist with this:

  • Be aware of changes in your mouth and notify your dentist immediately if you notice any.
  • Bring improperly fitting dentures to your dentist as soon as possible for repairs.
  • Do not smoke and limit your consumption of alcohol.
  • Visit your dentist regularly for your preventive exam and cleaning appointments. These usually include an oral cancer screening as part of your care.

Remember, ill fitting dentures are more than just a cosmetic issue. They can cause a variety of painful problems ranging from sores to infections and even oral cancer. Thus, if you notice your prosthetics or your mouth have changed, don’t wait for things to get worse.
