We are so confused about dental care. My husbands treatment ended July 3, we were never told about fluoride trays or prescription fluoride toothpaste and in October I found this website, so I started inquiring of his Drs about it. They were clueless and our insurance has denied a referral to a oncologist dentist. So he went to his regular dentist and he just cleaned his teeth and gave him some prescription fluoride toothpaste to use at night. Has anyone else encountered this problem and how important are fluoride trays. Is there research info on this that we could show our Dr's? We are in Oklahoma, US. We thought we were being treated at a top cancer center in OK, but now we wonder?
