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 you are seeing in the mirror is a denture sore or not.
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.

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, and 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.
Need Help with Dentures or Oral Health?
If your denture sores keep coming back, the most common reason is that the denture no longer fits properly. At Danforth Dental Centre in Toronto, we adjust and reline dentures for patients across East York and Greektown. A same-day assessment is often possible.

Ensure Proper Fit
Make sure your dentures actually fit your mouth. If they sit right and don’t wobble, your gums won’t get those annoying rubs and sore spots.
Good Oral Hygiene
Keep your mouth and dentures clean. Brush gently, rinse often, and give bacteria the boot. Your gums will stay happy and fresh.
Maintain a Balanced Diet

Feed your mouth some good stuff! Eating healthy foods helps your gums stay strong and heal faster, so sores don’t stand a chance.
Use Denture Adhesive
Slap on some denture glue to keep things in place. When your dentures don’t slide around, your gums get a break, and those pesky sore spots won’t appear.
Give Your Gums a Break
Take your dentures out for a few hours, especially at night. Let your gums breathe and chill, it’s like a mini spa for your mouth.
Regular Dental Visit
Don’t ghost your dentist! Checking in now and then keeps your dentures fit nicely and catches any potential sore before it starts.

What are the oral lesions associated with dentures?
Oral lesions from dentures are basically spots where your gums get irritated or damaged. They can show up as red patches, small bumps, or even tiny ulcers, usually where the dentures press or rub the most.
-
What are the signs of ill-fitting dentures that can result in painful sores?
One clear sign is when your dentures keep slipping or rubbing in the same spots, causing red, sore areas on your gums. If you ignore them, those spots can get worse and even lead to infections, so it’s a good idea to see your dentist.
-
How long do denture sores take to heal?
Most denture sores begin to improve within a few days once the source of irritation is removed. Minor sores often heal in 7 to 14 days. If the denture continues to rub against the same area, healing may take longer, or the sore may worsen.

Mild denture sores can often be managed at home by removing dentures at night, rinsing with warm saltwater, and keeping them clean. However, home care only helps relieve symptoms. If the denture does not fit properly, a professional adjustment is usually needed.

You should see a dentist if the sore lasts longer than one to two weeks, becomes increasingly painful, shows signs of infection, or makes it difficult to wear your dentures.
-
How do I know if my denture needs adjusting?
Your denture may need adjusting if you notice recurring sore spots, pain while chewing, looseness, clicking, difficulty speaking, or the denture shifting when you eat or talk. Changes in the shape of your gums and jaw over time can affect the fit, which makes periodic adjustments an important part of denture care.
