I am not sure what they will want to do other than remove the tissue and wait for pathology - yet again. Unless it's proven cancer doing something more invasive might be overkill, though it is good to have it monitored what is causing the dysplasia might be a place to look. Is your tongue being irritated by say a molar? Sharp tooth? Have you had a recent cap? Filling? Possibly you are allergic to the amalgam ? Do you unconsciously bite the area? Eat something you are sensitive to? Habits? (Chewing tobacco? Heavy drinking? Smoking?) hugs and best of luck.
