This morning, on the road, I brushed my teeth with a travel toothbrush. I had forgotten my toothpaste. As I brushed, I could taste the toothpaste from past poor-rinsing. I wondered how much fluoride I still had in the bristles, and whether the fluoride could be delivered without toothpaste more efficiently (as I brushed).
