Asking for your advice and what you do about tooth brushing. Is baking soda okay to use? I know you don't have to use anything but I kind of like the idea of the possible whitening aspect of baking soda (or is that a myth)? One of my friends uses baking soda mixed with coconut oil. what do you think of that? I tried it. it's kind of weird and slimy in my mouth. thanks in advance for your input.
