I have oral lichen planus for over 10 years. My dentist gives me a steroid gel to put on it when it's bad but I did some research and started making my own toothpaste. I have not had a flair up in over 3 years. I mix equal parts(one tablespoon) baking soda and coconut oil and several drops of Act flouride to make my dentist happy. It takes some getting used to but after a while it won't bother you. You can also add organic peppermint oil from a health food store to it if you like the minty taste. Google it. There are many variations out there but it has helped me tremendously. I also mentioned having my teeth pulled but my dentist said it would not help as it would still affect your gums and inside cheeks. Hope this helps.
