Stomatitis Venenata from Dentures: Allergic Contact Dermatitis of the Mouth

Stomatitis venenata is allergic contact dermatitis of the oral mucosa triggered by denture materials (acrylic resin, metals), dyes, or adhesives.

Symptoms

• Erythema, edema, burning, itching of mucosa
• Vesicles or ulcerations in severe cases
• Symptoms correlate with denture wear

Management

• Remove allergen: switch denture material (e.g., to hypoallergenic acrylic, metal-free), change adhesive.
• Topical corticosteroids (e.g., triamcinolone oral paste) for symptom control.
• Patch testing identifies specific allergen.

Denture hygiene and regular dental review prevent irritation and allow early detection.
