Dental Management of Patients with Oral lichen planus
Important — second opinion only. DentiCision provides an evidence-based second opinion to assist the dentist.

Oral lichen planus — confirm current activity
Oral lichen planus is a chronic immune-mediated condition and an oral potentially malignant disorder (malignant transformation ≈1.1–1.4%). Reticular forms are usually asymptomatic; erosive forms are painful and can flare with trauma.
Emergency vs routine management
If EMERGENCY — what to do
- • Treat pain/infection now with the gentlest technique — emergency care is never delayed.
If ROUTINE — what to do
- • Confirm disease activity to see the routine-care plan.
Clinical precautions
- • Review every 6–12 months; biopsy or refer non-healing, red, ulcerated or indurated areas, or any change in appearance
- • Antibiotic prophylaxis is NOT required for oral lichen planus
- • Erosive/symptomatic: topical corticosteroid (e.g. clobetasol or betamethasone mouthwash); watch for secondary candidiasis
- • Lichenoid lesions in contact with amalgam: consider patch testing / replacing the restoration
- • Minimise mucosal trauma; smooth sharp cusps and restoration margins
Information & tests to request
- • Is Oral lichen planus currently active in the mouth? — Elective treatment is deferred during an active flare because trauma worsens lesions; quiescent disease is treated with precautions.
