Management of Sore Gums from Dentures
For sore gums caused by dentures, you should first remove the dentures as much as possible during treatment, ensure meticulous oral hygiene of both the mouth and dentures, and have the denture fit and occlusion professionally evaluated and adjusted by a dentist.
Immediate Steps
The most common causes of denture-related gum soreness are mechanical trauma from poor denture fit, fungal infection (particularly Candida albicans), and bacterial plaque accumulation 1, 2, 3. Your approach should address all three simultaneously:
1. Denture Relief and Wear Reduction
- Minimize denture wearing time during the acute phase 1
- If there are obvious pressure points or areas of trauma, the denture base should be relieved by a dental professional 4
- This allows the traumatized tissue to heal and reduces ongoing mechanical injury
2. Hygiene Protocol
- Clean the dentures meticulously—poor denture hygiene is strongly associated with denture sore mouth 3
- Clean the oral mucosa thoroughly as well 1
- This addresses the bacterial plaque component that contributes to inflammation
3. Antifungal Treatment
Since Candida infection is present in approximately 73% of patients with denture sore mouth (compared to only 22% of controls) 3, antifungal therapy is often necessary:
- Nystatin or ketoconazole are effective first-line treatments 1
- Treatment should continue until complete resolution of the infection before proceeding to denture adjustment 1
Sequential Treatment Algorithm
The evidence supports a specific order of treatment 1:
- Initiate antifungal medication (if fungal infection suspected based on appearance)
- Implement strict oral and denture hygiene while minimizing denture wear
- Achieve complete resolution of the infection/inflammation
- Only then proceed to denture adjustment and occlusion correction
Professional Denture Evaluation
Once acute symptoms resolve, the denture itself must be addressed 1, 3:
- Assess denture fit and stability—unstable, traumatogenic dentures will cause persistent problems even after treatment 3
- Evaluate occlusion for balance
- Identify areas requiring relining due to maladjustment to soft tissues 1
- In some cases, soft relining material may be needed for 2 months to enhance healing 4
Important Caveats
A critical pitfall: Not all "denture sores" are simple trauma or infection. One case report documented a palatal perforation caused by an impacted canine tooth with deep caries underneath the denture 4. While rare, this emphasizes that:
- Persistent lesions require thorough examination
- Dark spots, significant swelling, or non-healing ulcers warrant radiographic evaluation
- Biopsy may be necessary to exclude malignancy, as chronic denture trauma can rarely predispose to oral carcinomas 2
Treatment failure: If symptoms persist despite new dentures and appropriate treatment, a combined nystatin-chlorhexidine regimen resolved 7 out of 9 persistent cases in one study 3. The remaining failures were due to unstable dentures requiring further mechanical correction.
When to Seek Immediate Dental Care
Refer urgently if you observe:
- Tissue perforation or deep ulceration
- Hyperplastic tissue response (requires surgical excision) 5
- Non-healing lesions despite appropriate treatment
- Severe pain or inability to eat
Regular recall examinations are essential for all denture wearers to prevent or minimize these lesions, as most are preventable with proper care 5, 2.
