My husband had his first round ot RT in the fall of 2015 at Mayo jville. Before treatment began he was sent to a dentist to be fitted for fluoride trays, with directions to use them every day. He has since had two more rounds of RT. He is not compliant with the daily floruide, but probably 2 x week. I make an appt with our family dentist every six months. (Give him 24 hrs notice, so he can't back out)

He tried a new product called SalivaMax rinse which showed promise, but after a couple of weeks it gave a metallic taste and he stopped using it. Maybe it would help someone else. It is prescription: http://www.forwardscience.com/salivamax
