Review title is more like diatomacious earth rather than baking soda [SEP] I have used Tom's of Main for the last 20 plus years, but thought I would give this product a try.  It is a tiny jar, so unless you are saving dental bills, it isn't very cost efficient compared to many available natural toothpasts.  I am primarily avoiding fluoride and other ingredients I can't pronounce just for general purposes, not to address any mouth / gum issues.  It is quite gritty, more like diatomacious earth rather than baking soda.  Even a little grittier than the polish product the dentist uses after your cleaning is completed.  The all natural flavor is quite strong, which I like to think is doing great things for my gums, but some would find it too much.  There is zero foaming, just mixing with the saliva produced while brushing, and I haven't mastered the spilling out of my mouth during the brushing process . . I have to make sure to lean over the sink bowl!  It does leave my mouth and teeth clean and refreshed, it just isn't all that pleasant to use.  I haven't used it long enough to weigh in on the whitening property.  I will porbably use this jar completely and try another natural product for comparison.
