I have had OLP for many years. A dermatologist recommended Lyderm gel and it worked great for me. She also suggested that I mix 50% liquid children's Benadryl and 50% liquid Gaviscon together and use it as a mouthwash two to three times a day, as needed. It was amazing. It calmed the pain and I didn't have to use the Lyderm gel so much. Do not swallow it, just rinse and spit it out. She also recommended that I use an electric round toothbrush and a water pic instead of floss, so as not to irritate the gum tissue. I hope this helps and keep smiling. It is always better when you smile.
