Only do it once a week, baking soda is abrasive and can weaken the enamel on your teeth. it is VERY effective. I would not use it if you have sensitive teeth or bleeding gums.How often should you brush your teeth with baking soda to obtain whiter teeth?
you could have naturally colored teeth, so the affect varies. but the procedure itself can be used as often as you wish to.
It's pretty effective but tastes terrible, twice a day should do it.

take colgate white strips for your teeth instead of using baking soda
