Synopsis of Denture Sores

Denture sores are painful, inflamed areas on the gums, inner cheeks, or roof of the mouth caused by poorly fitting or unclean dentures. These sores can appear as red patches, raw spots, blisters, or ulcers, often triggered by friction, pressure, or bacterial/fungal buildup beneath the dentures. They may lead to discomfort during eating or speaking and increase the risk of oral infections if left untreated.

This condition is most common in new denture wearers or those with ill-fitting, worn, or unclean dentures. It can be exacerbated by dry mouth, nutritional deficiencies, or immune suppression. Denture-related stomatitis (inflammation of the oral mucosa) may also be associated with Candida overgrowth (oral thrush).

Types of Denture Sores:

  • Pressure Ulcers: From uneven pressure or poorly fitting dentures.

  • Friction Irritation: From movement or sliding of the denture.

  • Denture Stomatitis: Inflammation caused by Candida or poor hygiene.

  • Traumatic Ulcers: From sharp denture edges or rough acrylic surfaces.

Common Causes:

  • Ill-fitting or loose dentures

  • Poor oral or denture hygiene

  • Wearing dentures overnight

  • Dry mouth (xerostomia)

  • Candida (yeast) overgrowth

  • Allergy to denture materials (rare)

  • Nutritional deficiencies (vitamin B12, folate, iron)

Severity Factors:

  • Mild soreness may heal with rest and hygiene adjustments.

  • Persistent sores can become infected or lead to chronic inflammation.

  • Severe or recurrent sores may indicate underlying fungal infection or systemic issues.

When to See a Doctor or Dentist:

  • Persistent sore spots or ulcers lasting more than 10 days

  • Pain or discomfort interfering with eating or speaking

  • Redness, swelling, or signs of infection (pus, odor)

  • White patches suggesting oral thrush

  • Dentures that rock, slip, or rub frequently

  • Recent weight loss or bone loss changing denture fit

Natural remedies for Denture Sores

Remove dentures overnight: Allows tissues to rest and heal.

Rinse mouth with warm salt water: Promotes healing and reduces irritation.

Apply aloe vera gel: Natural anti-inflammatory and soothing.

Cold compresses: Reduce swelling and numb sore areas.

Maintain denture hygiene: Brush dentures daily and soak in antibacterial solution.

Check for rough edges: Have dentures adjusted by a dentist.

Stay hydrated: Prevent dry mouth that worsens friction.

Avoid spicy, acidic, or very hot foods: These can aggravate sores.
