Wearing dentures can significantly improve a person’s ability to eat, speak, and smile with confidence. However, it’s not uncommon for denture wearers to experience soreness in the mouth, especially during the initial adjustment period or when dentures don’t fit properly. These sores can be uncomfortable, lead to infections, and ultimately discourage consistent use of dentures. The good news is that there are effective ways to relieve, treat, and even prevent these issues.
In this in-depth guide, we’ll explore the causes of denture-related sores, the best treatment options available, and how to maintain long-term oral comfort and health.
Understanding Denture-Related Sores
Before diving into treatment methods, it’s crucial to understand why these sores develop in the first place. Soreness from dentures usually stems from one or more of the following:
1. Poor Fit
Ill-fitting dentures can place excessive pressure on certain areas of the mouth. Over time, this pressure causes friction, leading to irritation and ulcers.
2. New Dentures
For new denture wearers, the oral tissues need time to adapt. The gums and surrounding structures may not yet be accustomed to the constant presence of the denture, which can cause sore spots during the breaking-in period.
3. Improper Cleaning
Neglecting proper hygiene can lead to the buildup of plaque and bacteria under the denture, causing infections or inflammation known as denture stomatitis.
4. Underlying Oral Conditions
Conditions such as dry mouth (xerostomia), oral thrush, or previously undiagnosed allergies can contribute to soreness and irritation.
5. Night Wear
Wearing dentures 24/7, especially overnight, deprives the tissues of time to rest and heal. This can lead to pressure points and fungal infections.
Symptoms of Denture Sores
Denture sores can manifest in several ways. If you’re experiencing any of the following symptoms, you may be dealing with sore spots caused by your denture:
- Red, inflamed areas on the gums
- Pain or discomfort when chewing or speaking
- Small ulcers or lesions on the soft tissue
- Burning sensation, especially with spicy or acidic foods
- Swelling of the mouth tissues
- Persistent bad breath (halitosis)
Best Ways to Get Rid of Sore Caused by Dentures in Mouth
Now that we’ve identified the common causes and symptoms, let’s dive into the most effective ways to treat and eliminate denture-related sores.
1. Visit a Dental Professional for Adjustment
One of the most effective first steps is to visit your dentist for a thorough evaluation. A dental professional can determine whether the denture is fitting properly or if there are pressure spots contributing to the soreness.
What the Dentist Will Do:
Assess fit: Dentists may use pressure-indicating paste to identify sore spots.
Make adjustments: The denture may need to be filed down or relined to reduce pressure on sensitive areas.
Recommend reline or remake: In some cases, if the denture is too old or significantly ill-fitting, a complete reline or remake may be necessary.
Importance of Regular Check-Ups
Even long-time denture wearers should have regular dental check-ups. The shape of your gums and jawbone can change over time, causing previously well-fitting dentures to become loose.
2. Use a Denture Adhesive
Denture adhesives can provide temporary relief by creating a cushion between the gum tissue and the denture base. This can reduce friction and stabilize the denture, preventing it from moving around and causing more irritation.
How to Use Properly:
Clean your denture and mouth thoroughly before applying the adhesive.
Use a small amount—too much can cause excess material to leak and cause additional irritation.
Remove adhesive and clean the denture daily.
While adhesives are helpful, they should not be a substitute for poorly fitting dentures. If you find yourself increasingly reliant on adhesives, it may be time for an adjustment or a new denture.
3. Rinse with Warm Salt Water
Salt water rinses are a natural, gentle remedy for mouth sores. They promote healing, reduce inflammation, and keep the area clean.
Directions:
- Mix ½ teaspoon of salt in a cup of warm water.
- Swish the solution around your mouth for 30 seconds.
- Repeat 3–4 times a day.
Avoid using overly hot water, as it can further irritate already sensitive tissues.
4. Maintain Excellent Oral Hygiene
Proper hygiene is critical in preventing and treating sores caused by dentures. Bacteria thrive in moist, warm environments, and dentures can trap food particles and plaque if not cleaned properly.
Daily Routine:
Remove and rinse your denture after every meal.
Brush the denture daily using a soft-bristled toothbrush and non-abrasive denture cleaner.
Soak your denture overnight in a denture-cleansing solution.
Brush your gums, tongue, and palate with a soft toothbrush to remove bacteria and stimulate circulation.
Maintaining a clean environment in your mouth not only prevents sores but also improves the overall lifespan of your denture.
5. Avoid Wearing Dentures at Night
Your gums need rest, just like any other part of your body. Removing your denture before bed allows the tissue to recover from daily stress and pressure.
Benefits of Removing Dentures Overnight:
- Reduces risk of fungal infections (especially Candida albicans)
- Allows the gums to “breathe” and heal naturally
- Prevents constant pressure on sensitive tissues
Always store your denture in water or a recommended soaking solution overnight to keep it from drying out and warping.
6. Use Topical Gels and Creams
There are several over-the-counter gels and ointments designed to provide temporary relief from denture-related sores. These products often contain numbing agents or soothing ingredients that can ease discomfort while the tissue heals.
Popular Ingredients:
Benzocaine: A local anesthetic that temporarily numbs the sore area.
Aloe Vera: Natural anti-inflammatory and soothing properties.
Hydrocortisone: Reduces inflammation but should be used sparingly and under supervision.
Be sure to follow product instructions carefully and consult your dentist before long-term use.
7. Adjust Diet Temporarily
During flare-ups of sore spots, it’s wise to adjust your diet to avoid aggravating the tissue.
Recommended Foods:
- Soft foods like yogurt, mashed potatoes, scrambled eggs
- Cold items such as smoothies, ice cream, or cold soups
- Non-acidic beverages and low-sugar options
Avoid:
- Crunchy or sharp-edged foods (e.g., chips, crusty bread)
- Hot or spicy foods
- Acidic fruits (like citrus) and vinegar-based dressings
Eating mindfully while your mouth heals can significantly speed up recovery and reduce pain.
8. Consider a Soft Reline
If your denture causes ongoing discomfort, your dentist might suggest a soft reline. This involves applying a cushioning layer to the inner surface of the denture, which makes it more comfortable against the gum tissue.
Benefits:
- Distributes pressure more evenly
- Reduces friction and sore formation
- Provides temporary comfort while waiting for a new denture or permanent reline
Soft relines are especially beneficial for individuals with sensitive gums or significant bone loss.
9. Address Dry Mouth
Dry mouth can exacerbate sore spots because saliva acts as a natural lubricant. If you suffer from xerostomia, especially due to medications or medical conditions, the lack of saliva can make dentures feel harsh and uncomfortable.
Solutions:
Drink water frequently throughout the day
Use saliva substitutes or oral moisturizing gels
Avoid caffeine, alcohol, and smoking
Chew sugar-free gum to stimulate saliva (if you still have some natural teeth)
Saliva is crucial for comfort, digestion, and oral health—don’t overlook its role in denture comfort.
10. Treat Any Underlying Fungal Infections
Sometimes, persistent soreness is due to denture stomatitis, a fungal infection caused by Candida albicans. This condition is often characterized by red, inflamed tissue under the denture.
Signs of Denture Stomatitis:
- Red, smooth area beneath the denture
- Mild discomfort or burning sensation
- Bad breath or unpleasant taste
Treatment:
- Antifungal medications (prescribed by your dentist or doctor)
- Enhanced oral hygiene practices
- Soaking denture in antifungal solutions
- Removing the denture at night
This condition should not be ignored, as untreated fungal infections can lead to more serious complications.
11. Replace Old Dentures
All dentures have a lifespan. Over time, the materials wear down and the shape of your jaw and gums change, making an old denture increasingly uncomfortable.
Signs You Need a New Denture:
- Frequent sore spots
- Difficulty speaking or chewing
- Loose fit or slipping
- Cracks or worn-down teeth on the denture
Most dentures last 5–10 years depending on wear and maintenance. If yours is approaching this age, it may be time to get a new one.
12. Practice Patience During the Adjustment Period
For new wearers, some soreness is to be expected. The oral tissues need time to adapt. During this phase:
Follow your dentist’s instructions carefully
Attend all scheduled adjustment appointments
Give yourself time to adjust, but don’t tolerate persistent pain
If discomfort lasts longer than two weeks or worsens, consult your dental provider.
13. Use Ice Chips or Cold Compress
When immediate relief is needed, sucking on ice chips or applying a cold compress to the cheek can help reduce inflammation and numb sore tissues.
Don’t apply ice directly to soft tissues
Limit use to 10–15 minutes per session
Repeat as needed, several times a day
This is a simple, drug-free method that can make a big difference, especially during the early days of denture wear.
14. Consider Implant-Supported Dentures
If traditional dentures consistently cause issues, implant-supported dentures may be a more comfortable and stable alternative. These dentures are anchored to dental implants placed in the jawbone.
Advantages:
- More secure and less movement
- Less pressure on the gums
- Better chewing efficiency
- Reduced sore spots
Implant-supported dentures are an investment, but they offer a significant upgrade in comfort and function for many patients.
Conclusion
Denture-related soreness can be a frustrating barrier to enjoying the many benefits dentures provide. However, with the right approach, these issues are usually manageable and preventable. Whether it’s adjusting the denture fit, improving hygiene, modifying your diet, or exploring alternative denture options, relief is within reach.
Remember: Dentures should enhance your quality of life—not diminish it. If sore spots are interfering with daily activities, don’t hesitate to consult your dentist and explore the solutions outlined here.
