Brief Answer:
start with oral steroids

Detailed Answer:
Hello,
There is not cure for oral lichen planus so the goals of treatment are to decrease symptoms and minimize scarring.
A combination of measures can be used to treat lichen planus and this often depends upon the patient factors such as the extent of disease and tolerance to treatments.
In general topical treatments are preferred because they have less side effects than oral treatments.
Topical steroids are used first and additional treatments like topical calcineurin inhibitors and intralesional corticosteroid injections may be used if the topical steroids do not work.
Oral treatments are reserved for patients who fail the above treatments or have disease that affects other areas of the body.
See a dermatologist for the best available options.
Regards,
Dr. Robinson
