I've had OLP for ?maybe 25 - 30 years. At one point it was erosive and dentist did not even have a clue about LP. I had to go to a teaching hospital to get a Dx. Over the years I tried so many toothpastes and mouth rinses. what I landed on that helps the most is: 1) gentle electric tooth brush, 2) baking soda and 3) rinse with hydrogen peroxide. Swish afterward with water. My gums are the healthiest they have ever been.
