Is there something that can be used instead of fluoride. I'm doing 5 minutes a day with dental trays. I'm going to ask my onco dentist about this, but I'd also like to hear opinions here.

Squamous cell carcinoma base of tongue. Lymph involvement unclear; staging placed at "2 or 3." Biopsy 4/18/2008. Treatment: IMRT every day for 7 weeks. Cisplaten once a week to sensitize cancer to radiation. Treatment ended 7/16/08. PET/CT shows no more cancer.
