Why Denture Sores Happen — and How to Stop Them
Denture sores are small but painful spots caused by rubbing, pressure, or bacteria buildup under dentures. For seniors, these sores can make eating and speaking uncomfortable — and even discourage wearing dentures altogether.
The good news? With the right fit, daily cleaning, and a few comfort tricks, you can prevent irritation and enjoy all-day comfort again.
1. Make Sure Your Dentures Fit Properly
The number-one cause of sore spots is an uneven or loose fit. Over time, natural changes in your gums or bone can cause dentures to shift. If your dentures move when you talk or eat, it’s time for an adjustment.
Visit your dentist for a reline or refit every year to maintain comfort and stability.
2. Keep Dentures Clean Every Day
Bacteria and food particles trapped under dentures can irritate gums and lead to infection. Always rinse after meals and brush dentures daily with a soft brush and denture cleanser.
Recommended Cleaners:
- Polident Denture Cleanser Tablets — removes 99.9% of odor-causing bacteria overnight.
- Efferdent Denture Cleanser — deep cleaning bubbles for fresh, comfortable dentures.
3. Use Denture Adhesive for a Secure Fit
Adhesives can cushion gums and prevent shifting that leads to friction and sore spots. Apply a small, even amount each morning, and clean off completely at night.
Top Picks:
- Poligrip Free Adhesive Cream — zinc-free and gentle on gums.
- Fixodent Plus Scope Adhesive — adds a fresh mint seal for comfort.
4. Give Your Gums a Rest
Take your dentures out for at least six hours every day (usually overnight). This gives your gums time to recover and stay healthy. Always soak dentures in water or cleanser when not in use.
5. Rinse with Warm Salt Water for Healing
If you develop sore spots, rinse your mouth with warm salt water (½ teaspoon salt in a cup of warm water) two to three times a day. It helps soothe inflammation and promote healing naturally.
6. Keep Your Mouth Moist
Dry mouth increases friction between dentures and gums. Use moisturizing mouth rinses or saliva substitutes to keep tissues lubricated.

7. Avoid Abrasive Toothpaste or Harsh Cleaners
Never use household cleaners, bleach, or whitening toothpaste on dentures. These can scratch or weaken materials, creating tiny pores that harbor bacteria and cause further irritation.
8. See Your Dentist if Pain Persists
Persistent sores lasting more than a week may signal a fit issue, fungal infection, or allergy. Don’t ignore them — your dentist can adjust your dentures or prescribe a soothing antifungal rinse.
Final Thoughts
Minor irritation is common when first wearing dentures, but ongoing pain isn’t normal. A well-fitted, clean set of dentures should feel natural and secure. Take care of your gums, keep everything clean, and check your fit regularly — and you’ll enjoy a confident, pain-free smile.
Comfort starts with care — and your smile deserves both.
