I am about to start week 5 of radiation and I am having a really hard time keeping my mouth clean. I don't have flouride trays, just a high flouride toothpaste that I was told to use after treatment. I have very healthy teeth. Never had a cavity or any kind of dental issue. I suspect that will change post-treatment. Anyway, I have been doing salt and baking soda rinses several times each day and scraping the yeast of my tongue with a little tongue cleaner. When I brush my teeth, my gums just bleed and bleed. I bought a waterpik but it stings like crazy so I haven't been using it. Any tips on how to take better care of my teeth until these sores and the thrush clear up?
