Tonight, I noticed three white marks on my gums near the gumline after brushing my teeth. I am concerned about this. I have been online trying to get information. I had ulcerative colitis for many years; however, after having my entire colon removed and my rectum, I have not had any symptoms since 2010. Also, I have an ileostomy. Please advise if I have anything to worry about. I am also on Warfarin for the rest of my life due to a past history of DVT; hence, I must sometimes limit green vegetables. Please advise, as I have been quite ill, at times, since the late 80's, and the thought of another medical setback is a big concern to me now. Thank you very much.
