Does pure baking soda whiten teeth
Baking soda may remove some surface discoloration, but it does not bleach deeper tooth colour and should not replace fluoride toothpaste.
The short answer
Sodium bicarbonate cleans mechanically and may loosen external stains, while deeper colour comes from enamel translucency and dentin. Forceful or frequent scrubbing can irritate gums and wear surfaces.

How can I brush safely when trying to remove stains?
Use gentle brushing with a soft brush and fluoride toothpaste. Avoid acidic mixtures and abrasive polishing, especially if enamel is thin or roots are exposed.
When should new or uneven discolouration be examined?
Have new, uneven, painful, or one-tooth discoloration examined because decay, trauma, or internal staining may be involved.
Is the discolouration surface staining or inside the tooth?
Is the discoloration on the surface or inside the tooth, and what whitening method suits my restorations?
