If you are using dentures, you’d better know about some problems they can cause. Because of poor oral hygiene, ill-fitting dentures, or allergic reactions, dentures may create ulcers, inflammation, painful spots, and other issues that can make visiting an emergency dentist necessary. In the upcoming sections, we are going to show you some pictures of denture sores that can help you identify different types of them.

Different Types of Denture Sores
Here you can see a table that will help you identify denture sores, as well as their causes, appearances, and common locations.
| Type of Denture Sore | Cause | Appearance | Common location |
| Pressure sore | Excessive pressure from a poor denture fit or an uneven bite | Small, painful ulcer with a red base, sometimes whitish outline | Along denture-bearing ridges or thin mucosa |
| Frictional sore | Denture movement or rubbing during friction | Red, raw, inflamed patch without deep ulceration | Inner cheeks, lips, flanges of denture |
| Denture stomatitis | Continuous wear (esp. sleeping with dentures) and poor hygiene | Diffuse redness under denture, often painless, may burn | Palate under the upper denture |
| Epulis fissuratum | Chronic overextended flange rubbing in the vestibule | Fold(s) of excess fibrous tissue with a groove from the flange | Along the vestibule, especially anterior |
| Angular cheilitis | Saliva pooling at the mouth corners, Candida or bacterial infection, loss of vertical dimension from worn dentures | Red, cracked, sore lesions at the mouth corners | Labial commissures |

How to Identify Denture Sores from Other Oral Issues
If soreness occurs where the dentures make direct contact, it’s usually denture-related, often from mechanical trauma. However, if discomfort continues even after removing dentures, it may point to infections or more serious conditions. Generally, if the soreness improves once dentures are removed, they are the likely cause; but if it persists or worsens, other oral issues should be considered.
Persistent sores could be a sign that it’s time to consider a more permanent solution, such as dental implants for missing teeth.
Common Causes of Denture Sores

Dentures can irritate because of poor fit and uneven pressure points. If you wear dentures all day long, it will put constant pressure on the tissue and promote fungal growth, so try removing them from time to time. If you don’t clean your dentures daily, it can be a great place for bacteria and fungi. Also, some people are sensitive to the material used in the dentures and experience diffuse redness and burning.

Symptoms and Signs to Look For
Let’s learn how to recognize some symptoms related to the use of dentures:
- Pain or discomfort during denture use: Feel localized pain right under the dentures? That’s it! Chewing or speaking can also be painful.
- Redness or inflammation: It matches the shape of the denture surface, and can be diffuse or localized.
- Ulceration: A shallow open sore with a red or whitish center, and painful to touch or acidic foods.
- Swelling: When the soreness gets chronic, tissue can fold and thicken.
- Changes in fit: If dentures feel unstable and loose, it means the ridge shape has changed, and there are uneven pressure points.
- Burning sensation: Usually caused by denture Stomatitis and often felt on the palate or inner cheeks.
For some patients, transitioning from dentures to implants provides a more stable, comfortable solution. Learn more about the types of dental implants that may suit your needs.
How to Treat and Prevent Denture Sores

For preventing denture sores, some things you can do are visiting your dentist to make sure your dentures fit properly, practicing good hygiene, and removing them at night. Try to fix the dentures in place with denture adhesive so that they won’t be wobbly and loose. Also, don’t forget to drink plenty of water and eat well.
Treatment options
If you couldn’t prevent denture sores and they happened, here are some remedies:
- Remove or adjust the dentures: Go ahead, remove the dentures and see if it makes a difference. Do they need adjustment? You can visit a dentist and address the issue.
- Over-the-counter medications: Meds like ointments, anti-inflammatories, and antifungals can be great! They will fight pain and infection
- Address specific lesions: It really depends on what kind of lesions they are. Some require antifungal creams, while some of them need surgery.
- Soft liners for dentures: Ask your dentist to use soft liners, as they can protect your gums and reduce irritation.
- Salt water rinse: A classic home remedy! It can be used to cleanse the affected area and reduce inflammation.
Note: Don’t forget to visit your dentist regularly! You will have a better experience with dentures and prevent some problems from happening.
When to Seek Professional Help
Let’s say preventing denture sores was not successful, or you simply didn’t know about them. If the pain or infection persists, even after using home remedies, or it’s affecting eating and speaking, you should visit a dentist near me. Keep an eye on swellings and signs of infection, such as pus, bleeding, or fever. Also, when there is a noticeable change in the fit of your dentures, it’s better to get them readjusted.
Protect Your Gums by Addressing Denture Sores
Getting Dentures can be a great option if you are missing a couple of teeth. They can improve the bite force and the appearance of your smile cosmetically. But, if not careful, they can cause denture sores as you saw in the pictures of denture sores.
