Baking soda is good for teeth whitening
Baking soda can help remove some surface stain through mild abrasive cleaning, but it does not bleach the deeper color of enamel or dentin.
The short answer
Baking soda can help remove some surface stain through mild abrasive cleaning, but it does not bleach the deeper color of enamel or dentin. It is not a substitute for a dental examination or a formulated whitening product.
What is the direct answer?
What does this question mean?
Sodium bicarbonate is a fine alkaline powder that can disturb external stain during brushing. The result depends on the powder, brushing force, frequency, enamel condition, and whether the discoloration is on the surface or inside the tooth.
What can you do next?
Use a soft brush and avoid vigorous or repeated scrubbing with loose powder. For a color change beyond surface stain, a dentist can check for decay, fluorosis, tetracycline staining, trauma, or restorations and discuss peroxide whitening or another option.
When should you seek dental care?
Seek dental care for sensitivity, gum irritation, enamel defects, a gray or brown single tooth, or discoloration that does not brush away.
What should you ask the dentist?
Ask whether your discoloration is surface stain or intrinsic tooth color, and whether whitening, cleaning, bonding, or another treatment is appropriate.
