Baking soda as whitening teeth
Baking soda can help remove some surface stain through mild abrasion, but it does not bleach the internal color of a tooth.
The short answer
Sodium bicarbonate is a fine alkaline powder that can polish deposits on the outer enamel surface. It cannot change the shade of dentin beneath enamel, repair decay, or alter the color of fillings, crowns, or veneers.
What is the direct answer?
What does this question mean?
Use a soft toothbrush and fluoride toothpaste for routine care rather than scrubbing with dry powder. For a lighter overall shade, have the dentist check for disease and select a formulated peroxide treatment when appropriate.
What can you do next?
Seek care for sensitivity, worn enamel, gum recession, rough patches, pain, or discoloration that does not lift with cleaning. A single dark or gray tooth needs assessment before whitening.
When should you seek dental care?
Ask whether your stain is external or internal, whether enamel or dentin is exposed, and which whitening method protects your gums and existing dental work.
What should you ask the dentist?
Sodium bicarbonate is baking soda.
