Hi Jerry, When I was @ the "Spring Fling Tasting" to night, as luck would have it, a woman was there I met before & she mentioned her dentist has several "post cancer" patients & is very familiar with all the dental issues that can occur post TX. So, I am going to give him a call tomorrow. Also, the white patch on the side of my tongue (same side as my tumor was) has already had a biopsy (came back neg) & my rad. dr. calls the patch an "ulcer" I keep an eye on the size of it. Thanks again for your advice!
