It is safe to use baking soda—sodium bicarbonate— to whiten the teeth?
You don’t want to do this frequently. The abrasive properties that make it really effective to clean teeth will break down the protective outside layer of the teeth, and leave them vulnerable. Baking soda erodes the enamel on your teeth terribly. Yes, it does whiten the teeth but enamel is not replaceable and it is the only thing coating and protecting your teeth. My dentist suggested that if I want to do this, leave it for once every couple months.
I’ve never heard of brushing your teeth with just baking soda. I’ve heard that mixing hydrogen peroxide and baking soda into a paste can whiten your teeth. The hydrogen peroxide whitens and the baking soda acts as scrub. Either ways, I wouldn’t advise someone to do any. If you wish to whiten your teeth you can easily go to the dentist.
