I just use baking soda, it doesn't have the best of flavors, but it works. When out of Phase 1 I have several recipes, bing it, there are lots of recipes on the net.
I use fluoride-free toothpaste so it is hard to find something.
I've used Tom's fluoride-free Antiplaque & Whitening toothpaste most of the time. It is peppermint flavored but it contains no oils. Other Tom's toothpastes contain peppermint oil.
I finally found Dr. Ken's Cinnamon flavored Maximum Care Whitening toothpaste. It fluoride, oil & peppermint free. Unfortunately I had a reaction to something in it & my tongue felt like it was burned all the time. It was better a few days after I stopped using it. I went back to the Tom's.
I just got Supersmile Professional Whitening Toothpaste & it is has no fluroide & no oils & no mint. Whitens nice, too.
