i have no idea how to use baking soda?
a chemical right? not for baking cakes right?
i believe soda can clean for a month/2-3 weeks and you will get stains back right?

There is already a type of toothpaste that contains baking soda, have you tried that? You just use baking soda powder? I know you can buy as much as you want at Save-on foods.
i just went to the dentist yesterday... they said crest whitening strip is the best.. but because of a certain chemical that makes the strips, so if you use it too much it's not good for your teeth
surface stain you can remove by normal brushing....baking soda helps by acting as a abrasive
the strength of the strips are so weak that it can only bleach the surface stain
if the stain is deep inside the teeth.....go see a dentist
