Why Dentures Cause Mouth Ulcers
Your mouth isn’t a perfectly flat surface, and dentures don’t stay completely still. A denture can shift slightly while you’re eating, putting repeated pressure on one small area. If the edge is rough or the fit has become loose, that rubbing becomes much more noticeable.
A Denture That Used to Fit Fine
This catches people out. A denture that felt comfortable for years can suddenly start causing trouble because the shape of the gums and jaw changes over time. Weight changes can affect the fit too. So can wear on the denture itself.
What You Can Do Right Now
Give the sore a chance to settle. If you can safely go without the denture for short periods, especially while you’re at home, that takes pressure off the area. Keep the mouth clean and rinse gently with warm salt water if it feels soothing.
Get the Denture Checked
A dentist or denture professional can check the fit and see exactly where the pressure is coming from. An adjustment may be enough. Don’t try filing or cutting the denture yourself. That can turn a small fit problem into a much bigger one.
When a Denture Sore Needs More Attention
Most irritation from a badly fitting denture should improve once the pressure is removed. But a mouth ulcer that doesn’t heal deserves proper attention.
And don’t let the denture hide the problem. Taking it out briefly and looking at the sore can tell you whether it’s improving, although a proper examination is still the better answer.
The Part People Often Ignore
If an ulcer keeps appearing underneath your denture, the answer usually isn’t tougher gums or simply putting up with it. Get the fit looked at.
