Does using baking soda whiten teeth
Baking soda can remove some surface stains, but it does not change the natural color of teeth like peroxide whitening.
The short answer
Loose baking soda can remove some surface stains, but it does not change the natural color of teeth like peroxide whitening. Repeated scrubbing can abrade enamel or expose dentin.
What is the direct answer?
What does this question mean?
This question concerns extrinsic stain on enamel, such as discoloration from tea, coffee, or tobacco. Internal tooth color and stains within dentin need a different approach.
What can you do next?
Use fluoride toothpaste and a soft brush with gentle pressure. A dentist can assess tartar, erosion, decay, and restorations before discussing peroxide whitening.
When should you seek dental care?
Arrange an examination for one-tooth discoloration, sudden darkening, pain, sensitivity, or a rough surface. Facial swelling or trauma needs prompt care.
What should you ask the dentist?
Ask whether the color is surface stain, decay, fluorosis, trauma, or a restoration. Ask how whitening would affect fillings, crowns, or veneers.
