Ed, I use baking soda once in a blue moon to brush my teeth. I think it's a little to abrasive to use all the time. To help with that saltiness try mixing it with your regular toothpaste. I know here I can get baking soda tooth paste elminating the need to do that. But again probably cheaper to buy a box.

edit: looks like I was beat to the Arm & Hammer tooth paste..........
