How to whiten teeth with baking soda
Baking soda can remove some surface stain because it is a mild abrasive, but it does not bleach the internal color of a tooth and overuse can wear enamel o
The short answer
Baking soda is sodium bicarbonate, an alkaline powder with abrasive particles. It can loosen deposits on the outer enamel surface, while deeper discoloration from dentin, trauma, medication, or aging needs a different assessment.
What is safer than scrubbing teeth with baking soda?
Use a soft toothbrush and a fluoride toothpaste for routine cleaning rather than scrubbing with dry powder. If you use a baking-soda toothpaste, brush gently and avoid combining it with acidic liquids or abrasive powders.
When should unusual tooth colour be examined?
Book an examination for a single dark tooth, brown or white patches, pain, erosion, bleeding gums, or color that does not improve with normal brushing. Urgent swelling or trauma needs prompt care.
What should you ask about baking soda and whitening?
Ask whether the stain is external or internal, whether enamel wear or gum recession is present, and whether professional cleaning or a monitored whitening treatment is appropriate.
Frequently asked questions
Can baking soda replace toothpaste?
No. A fluoride toothpaste supplies cavity protection that plain baking soda does not provide in the same way.
Can lemon be mixed with baking soda?
Avoid acidic mixtures because acid can soften enamel while abrasion removes the softened surface.
