Is it a good idea to try teeth whitening with baking powder?

Waste of time: Baking soda will not whiten your teeth, it will only help remove superficial stains. Overuse can wear away your enamel. You'll have to use whitening products that are formulated for this purpose, either purchased otc at your pharmacy or applied professionally by your dentist..

No: Unfortunately you will not get any 'whitening' effects from baking powder, but you will have an exceptionally fresh feeling mouth! i hope this helps.

Ineffective: Save the baking powder for a recipe. Talk to your dentist about effective alternatives.
