Denture Sore Spots While Eating: Causes, Fixes & When to See a Denturist

If every meal leaves your mouth feeling worse, not better, you’re not imagining it. Sore spots caused by dentures, especially while eating, are surprisingly common. They can sneak up fast, even if you’ve been wearing dentures for years without a problem.

Here’s what’s likely going on, and more importantly, what you can do about it.

Why Denture Sore Spots Keep Coming Back

Sore spots usually happen when dentures rub or press unevenly against the gums or cheeks. That pressure can cause tiny cuts or bruises. Over time, it adds up to pain that makes eating a chore.

Here are potential culprits:

Loose fit: Dentures that have shifted slightly out of place
Hard or rough foods: Like toast, chips, or nuts
Crumbs or grit under the denture: Even a small bit can cause irritation
Bone changes: As gums and bone shape-shift, pressure points develop

For those who haven’t seen a denturist in a while, these issues tend to go untreated longer.

The result? Discomfort, frustration, and avoiding favourite foods.

If You're New to Dentures, Some Soreness is Normal

Getting dentures is a bit like a rehabilitation. Your mouth needs time to adjust to wearing a new prosthetic, and that adjustment period almost always includes some tenderness.

Here's the thing: your job is to get used to wearing your new dentures. Our job is to address any soreness caused by rubbing or pressure points! That's how the process works best.

Some people are more prone to sore spots than others. If you're on medications, for example, you may experience more irritation. Most medications cause dry mouth, which means the gum tissue is less healthy and less able to absorb the natural movements of the denture. It's not your fault, it's just something we need to work around together.

That's why Saberton offers a free 90-day adjustment period with every new denture. No extra fees, no hesitation needed. If something hurts, come in. We'll fix it.

Too many patients sit at home and suffer because they're worried about being charged for every visit. At most dental practices, that's exactly what happens. But at Saberton, adjustments are included, so there's no reason to wait it out.

Spotting the Signs Early

These sore spots often start off mild: a little tenderness here, a slight sting there. But with time, the pain can increase.

Common signs include:

Reddish or raw patches on the gums
Pain while chewing or speaking
Swelling or sensitivity in one area

If it hurts to bite down, or if you’re shifting food to one side of your mouth, your dentures may be to blame.

Simple Fixes You Can Try at Home

There are some quick ways to give your mouth a break:

Rinse with warm salt water a couple of times a day
Stick to softer foods for now like soups, eggs, mashed veggies
Use a numbing gel (like what’s used for teething pain)
Take your dentures out overnight to let your gums rest

And don’t forget to clean daily! Debris left under dentures can make things worse fast. And if you’re still hurting after a few days, it may be time for a professional adjustment.

Fixing the Fit: When to See a Denturist

If the pain keeps coming back, chances are your dentures aren’t fitting the way they used to. It might be time for:

A reline: reshaping the inside of your dentures for better contact
A soft liner: a cushiony material for added comfort
A full replacement: especially if it’s been over five years since your last set

Implant-supported dentures are also worth asking about if sore spots are a regular issue. They stay in place better, which helps reduce rubbing. Learn more about what dental implants are and how they work.

Worried about cost? Saberton helps patients find options that fit their budget. We’ll also check if you qualify for CDCP coverage.

And if you're a Saberton patient with new dentures, remember: your first 90 days of adjustments are included at no extra charge. Don't wait until it's unbearable. Come in at the first sign of discomfort and we'll help get you sorted.

Denture Sore Spots: Common Questions

Here are answers to common questions about denture sore spots. For more comprehensive information, visit our FAQ page.

Is some pain normal with new dentures?‍

Yes, at first. But pain that doesn’t ease up should be looked at.

Can I still eat crunchy foods?‍

Sure, once sore spots are gone and your dentures fit well. Ease back in slowly.

Does sleeping in dentures make it worse?‍

Definitely. Gums need a break, and wearing dentures 24/7 keeps pressure on them.

There’s no redness, but it still hurts. Why?‍

Pain can come from deep pressure points, even if the surface looks okay. A denturist can spot the cause.

Do I have to pay for adjustments if my new dentures cause sore spots?

Not at Saberton! Every new denture comes with a free 90-day adjustment period. If something isn't fitting right, just come in. We include adjustments so you never have to choose between comfort and cost.
