Replacing missing teeth with dentures is a common and effective solution, but getting used to them can take time. When you first start wearing them, it’s not unusual to feel a bit of discomfort. One of the most common annoyances is little painful spots called denture sores. They pop up from pressure, bacteria build-up, or just your denture not fitting right. The good news? There are easy ways to ease the pain and simple treatments to stop things from getting worse. Stick around as we’re going to show pictures of denture sores so you know what to look out for.
Pictures of Denture Sores
Here you can see some of the pictures of denture sores:



What Denture Sores Look Like
Dental sores usually appear as red or irritated spots on your gums where dentures rub. Some may have small bumps, swelling, or tiny ulcers, and they can feel sore or uncomfortable when you eat or talk. Checking for these early can help prevent bigger problems.
Different Types of Denture Sores
| Type | Appearance | Common cause | Notes |
| Pressure Sores | Red, sensitive spots | Ill-fitting dentures | Usually on the ridge where dentures press |
| Ulcers | Small open sores | Constant friction | Can be painful, may bleed slightly |
| Allergic Reaction | Redness, swelling | Material sensitivity | Often occur with itching |
| Fungal Lesion | White patches | Poor oral hygiene | May feel sore or burning |
Causes of Dental Sores
Denture sores don’t just appear out of nowhere; they usually have clear triggers. Learn about each one of the common causes in full detail, and check out pictures of denture sores to see how they can actually appear.
Allergic Reaction

Sometimes your mouth just doesn’t accept the material your dentures are made of. An allergic reaction can cause redness, swelling, even sores, kind of like your gums saying, “Nope, I don’t like this.”
Poor Oral Hygiene

If you don’t keep your dentures and mouth clean, bacteria can build up and irritate your gums. All that bacteria and plaque can easily turn into sores.

Prolonged Wear
When you keep your dentures for too long without giving your gums a break, it puts a lot of stress on them. That constant pressure will lead to sore spots that don’t have a chance to heal.
Ill-fitting Dentures
When dentures don’t fit the way they should, they press and rub on your gums in all the wrong spots. That constant pressure makes the skin sore and creates painful little wounds.
Bone and Gum Changes
As we get older, our gums and jawbone can shrink or change shape, which makes dentures fit differently over time. When that happens, even perfectly good dentures can start rubbing and causing painful sores.
Dry Saliva
When your mouth is too dry, dentures start rubbing against your gums more than usual. Without that natural slip, your gums get irritated and sore way more easily.
