Wearing dentures, whether partial or full, comes with an adjustment period. Unfortunately, one common complication is mouth sores or abrasions caused by ill-fitting dentures or friction during chewing and speaking. These painful spots can make everyday activities, such as eating and talking, quite uncomfortable. Luckily, over-the-counter (OTC) medicines and home remedies can help manage the discomfort and promote faster healing.
What Causes Sores from Denture Use?
Mouth sores related to dentures typically stem from the following causes:
1. Poor Fit
When dentures do not fit snugly, they can move during speaking or eating, rubbing against the gums and soft tissues. This repetitive motion causes irritation, inflammation, and sometimes open sores.
2. Accumulated Food Particles
Improper cleaning or not removing dentures overnight may lead to a buildup of food debris. This fosters bacterial growth and may result in infections or sores.
3. Allergic Reactions
In rare cases, the materials used in the denture base or adhesive may cause an allergic reaction that appears as inflammation or ulcers inside the mouth.
4. New Denture Adjustment
New dentures often cause temporary irritation as your mouth adjusts to the foreign appliance. Even with proper fitting, the mucosa may need time to adapt.
Common Symptoms of Denture-Related Sores
- Redness or inflammation
- Sensitivity when eating or drinking
- Open sores or ulcers on gums, cheeks, or tongue
- Burning or stinging sensation
- Difficulty chewing or speaking
OTC Medications for Treating Denture Sores
Several over-the-counter products can soothe and treat sores caused by denture abrasions. These options are typically available in pharmacies or drugstores and can be used safely at home.
1. Oral Analgesics
Topical numbing gels can offer temporary pain relief:
Benzocaine (Orajel, Anbesol): A popular oral anesthetic, it numbs the sore area, providing relief for a few hours.
Lidocaine (2% gel): Stronger than benzocaine, lidocaine is sometimes recommended for severe discomfort but should be used carefully.
2. Antiseptic Rinses
These help keep the mouth clean, preventing secondary infections:
Hydrogen Peroxide (3% diluted): Used as a mouth rinse, it helps cleanse sores and reduce bacterial load.
Chlorhexidine Gluconate (Peridex): While usually prescription-only, some OTC brands offer mild antiseptic mouthwashes that can be helpful.
3. Protective Pastes and Gels
These coat the sore area, creating a protective barrier:
Orabase with Benzocaine: A paste that sticks to moist oral tissue and numbs while shielding the area from further irritation.
Colgate Peroxyl Gel: Both antiseptic and soothing, this gel helps with healing and pain relief.
4. Oral Wound Healers
Some products are formulated to accelerate healing:
Canker-X Gel: Designed for canker sores but useful for denture abrasions, it uses aloe vera and benzocaine to heal and soothe.
Biotene Oralbalance Gel: Especially useful for dry mouth, this gel promotes a moist environment ideal for tissue recovery.
5. Anti-inflammatory Medications
Oral medications can reduce swelling and discomfort:
Ibuprofen (Advil, Motrin): Reduces inflammation and offers pain relief.
Acetaminophen (Tylenol): A suitable option for those who cannot tolerate NSAIDs.
Complementary Home Remedies
In addition to OTC medicines, several natural remedies can aid healing:
Salt Water Rinse
A warm salt water rinse (½ teaspoon in 1 cup of water) used 3–4 times a day can cleanse the mouth and promote healing.
Aloe Vera Gel
Known for its anti-inflammatory properties, applying aloe vera directly to the sore can speed healing.
Cold Compress
Pressing a cold compress or ice pack to the outside of the cheek reduces swelling and relieves discomfort.
Preventing Denture Abrasions
Prevention is crucial for long-term comfort and oral health.
Ensure Proper Fit
Visit your dentist regularly to adjust dentures as needed. Even minor shifts in gum structure can lead to poor fitting and sore development.
Use Cushioning Adhesives
Products like Fixodent or Poligrip can act as a cushion between the denture base and your gums.
Clean Dentures Daily
Soak dentures overnight and brush them daily to remove plaque, bacteria, and food particles that can lead to irritation.
Give Your Mouth a Break
Remove your dentures for at least six to eight hours each day—usually at night—to allow gum tissues to rest and recover.
When to See a Dentist
If OTC treatments and home remedies do not improve your symptoms within 7–10 days, it may be time to seek professional help. Persistent sores could indicate:
- Infections
- Fungal conditions like oral thrush
- Improperly fabricated dentures
- Underlying systemic conditions such as diabetes
Special Considerations for Diabetics and Seniors
People with diabetes or weakened immune systems should monitor denture sores closely. These populations are more prone to infections and slower healing. OTC treatments may need to be complemented with prescription medications if the healing process lags.
OTC Products to Avoid
Not all OTC treatments are appropriate for denture-related sores. Avoid:
Alcohol-based mouthwashes: These can dry out the mouth and worsen irritation.
Hydrocortisone creams: While useful for skin, they are not approved for use inside the mouth.
FAQs about Mouth Sores from Denture Abrasions
1. How long do denture sores take to heal?
With proper OTC treatment and good hygiene, most denture sores heal within 5–10 days.
2. Can I continue wearing dentures while treating sores?
It’s often advised to reduce wear time during healing. If sores are severe, avoid wearing them until tissues heal.
3. Are there any natural alternatives to OTC medications?
Yes, aloe vera, salt rinses, and honey have shown promise in reducing inflammation and promoting oral healing.
4. Should I switch to soft foods while healing?
Yes. Eating soft, non-acidic, and non-spicy foods can reduce irritation and speed up the recovery process.
5. Is it normal to have recurring sores?
No. Recurring sores may indicate poorly fitting dentures or an underlying condition. Visit your dentist for a proper evaluation.
Conclusion
Mouth sores from denture abrasions are common but manageable. With proper care, over-the-counter medicines like topical anesthetics, antiseptic rinses, and oral anti-inflammatories can bring significant relief. Pairing OTC treatments with good oral hygiene, regular denture maintenance, and dental check-ups can help prevent sores from returning. If symptoms persist or worsen, consult a dental professional to evaluate the fit of your dentures and rule out other conditions.
