Tests and diagnosis

By Mayo Clinic staff

Frequently, 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
