Can you whiten teeth with baking soda
Baking soda can remove some surface discoloration through mild abrasion, but it does not bleach the internal colour of teeth like peroxide-based whitening.
The short answer
Baking soda may polish away some external stain, but it cannot reliably whiten the deeper tooth structure.
How does baking soda affect tooth surface stains?
Baking soda is sodium bicarbonate, a fine alkaline powder with mild abrasive action. It can disturb surface deposits, while true bleaching uses peroxide chemistry to change coloured molecules within enamel and dentin. Excessive rubbing can wear enamel or expose sensitive dentin.
What is the safest way to control tooth stains?
Use a fluoride toothpaste and a soft brush for routine stain control rather than brushing with household powder. A dentist can check for decay, erosion, gum disease, fillings, or crowns and then recommend a whitening method matched to your teeth.
When should sensitive or damaged teeth be examined?
Arrange an examination before whitening if teeth are painful, translucent at the edges, cracked, decayed, or sensitive. Seek care for gum burns, persistent sensitivity, or a change in colour that affects one tooth.
Which whitening option suits your teeth and gums?
Ask whether the discoloration is surface stain or an internal change, whether existing fillings or crowns will match, and which whitening concentration and application method fit your enamel and gums.
