Tests and diagnosis
By Mayo Clinic staffFrequently, your dentist is the first to notice oral lichen planus symptoms during a routine examination. The condition often can be diagnosed just by examining the affected areas of your mouth. In some cases, though, you may need to see a doctor or dentist who specializes in dermatology or oral medicine for a definitive diagnosis and treatment.
To make a diagnosis, your doctor may:
- Ask about your symptoms
- Discuss your medical history
- Examine your mouth and other areas of your body
- Order tests, such as blood and allergy tests, to rule out other conditions, such as yeast infections and canker sores
- Take a biopsy of your lesions, especially if they're erosive or ulcerated
