Baking soda or baking powder for white teeth
Baking soda can remove some surface stain, but baking powder is not a teeth-whitening treatment; dental whitening uses peroxide.
The short answer
Baking soda may polish away some surface stain, but baking powder is not a whitening treatment; dental whitening uses peroxide-based products.
What is baking soda and how might it affect stains?
Baking soda is sodium bicarbonate, a mildly abrasive alkaline powder. Baking powder also contains an acid salt and a starch, so it is formulated for cooking rather than controlled tooth cleaning or bleaching.
How can you clean your teeth safely at home?
Use a soft brush and fluoride toothpaste for routine cleaning. For intrinsic colour or persistent tea, coffee, or tobacco staining, a dentist can examine the enamel, remove calculus, and select peroxide whitening or another treatment.
When does tooth discolouration need dental care?
Arrange an examination when discoloration is uneven, appears in one tooth, follows an injury, or comes with pain or sensitivity. Seek prompt care for swelling, a fever, or difficulty swallowing.
What should you ask about whitening and existing restorations?
Ask whether the colour is surface stain, enamel change, decay, or a restoration, and which whitening method matches your enamel and existing fillings, crowns, or veneers.
Frequently asked questions
Will either powder change the natural colour inside a tooth?
No. Surface polishing does not bleach intrinsic tooth colour; peroxide-based whitening or restorative treatment may be considered after an examination.
What if the stain is on a filling or crown?
Whitening changes natural tooth structure, not most tooth-coloured restorations, so the dentist must plan colour matching separately.
