Lichen Planus

Oral Lichen Planus

Oral Lichen Planus (OLP) is a non-infectious, chronic, ongoing, inflammatory condition that attacks the mucus membrane inside of your mouth. It probably fits into the category of diseases known as Autoimmune Disease. It certainly behaves like one where a given immune system fails to recognise that body’s tissue as friendly and attacks it as if it were hostile or invasive.


Oral Lichen Planus has an incidence of about 2% of the population, affects women and men in equal proportion and has an age of onset of over 50.
