Baking soda uses for teeth
Baking soda is sodium bicarbonate, a mildly abrasive alkaline powder that can help loosen surface deposits when used in an appropriate toothpaste.
The short answer
Baking soda is sodium bicarbonate, a mildly abrasive alkaline powder that can help loosen surface deposits when used in an appropriate toothpaste. It does not rebuild lost enamel, remove decay, or replace fluoride toothpaste and professional care.
How does baking soda clean deposits in the mouth?
Its fine particles provide mechanical cleaning, while its alkaline nature can neutralise acids in the mouth. The benefit depends on particle size, brushing pressure, frequency, and whether the product also contains fluoride.
How should you use baking soda toothpaste safely?
Use a commercially formulated fluoride toothpaste as directed and brush with a soft brush using light pressure. Avoid making a rough paste from household powder or scrubbing hard, because abrasion can wear exposed dentine, root surfaces, and softened enamel.
When should tooth changes be checked by a dentist?
Seek dental care for brown or white changes, holes, sensitivity, bleeding gums, or persistent bad breath instead of trying to polish them away. A dentist can distinguish stain from decay, erosion, fluorosis, calculus, or gum disease.
What should you check in a baking soda toothpaste?
Ask whether the product contains fluoride and whether its abrasivity suits your enamel and exposed roots. Ask what caused the discolouration or sensitivity and whether cleaning, filling, desensitising treatment, or whitening is appropriate.

It can remove some surface deposits, making teeth look cleaner, but it does not bleach intrinsic tooth colour.
Can I brush with it every day?
