Common treatments for oral lichen planus include caring for sharp teeth or broken prostheses that may irritate the area, changing any medication the patient may be taking and eliminating tobacco and alcohol consumption, as noted by Medscape. Adding more fruits and vegetables to the diet may also help.
The most important thing a patient and his or her doctor can do is to remove anything that might be irritating the area, allowing it to heal faster while reducing pain. The goal is to increase the time between and severity of symptoms and flare-ups.
Left untreated, oral lichen planus can lead to oral cancer, and there is currently no form of treatment available to cure the condition.
