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 kinds of tooth stains can baking soda affect?
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.
How can you clean stained teeth without abrading enamel?
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 tooth discolouration be checked by a dentist?
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 about the cause of tooth discolouration?
Ask whether the color is surface stain, decay, fluorosis, trauma, or a restoration. Ask how whitening would affect fillings, crowns, or veneers.
