How to use baking soda for your teeth
Baking soda is sodium bicarbonate, and it should be used only as directed in a formulated toothpaste rather than as a substitute for routine fluoride toot.
The short answer
Baking soda, or sodium bicarbonate, is a mild alkaline powder that can help loosen surface deposits when incorporated into a toothpaste. It does not replace fluoride, which helps remineralize enamel, and loose powder does not provide the controlled formulation of a dental product.

What determines whether baking soda may harm tooth surfaces?
The relevant risks depend on particle abrasivity, brushing pressure, frequency, exposed dentine, gum recession, and any acidic erosion or enamel defect already present. Mixing it with acids or scrubbing aggressively can irritate gingiva and wear tooth surfaces.
How should you brush daily to protect your enamel?
Brush twice daily with a soft brush and a fluoride toothpaste. If you want a product containing sodium bicarbonate, choose a formulated toothpaste and follow its label; do not use it to treat toothache, gum disease, cavities, or stains beneath enamel.
When should sensitivity or staining be assessed by a dentist?
Ask for a dental review if teeth are sensitive, surfaces look worn, gums recede, or you are using powder because of persistent staining or bad breath. Pain, a cavity, or bleeding needs diagnosis rather than abrasive home treatment.
What should you ask about toothpaste for your teeth and gums?
Ask which toothpaste suits your enamel, dentine, gum condition, and staining pattern. Ask whether the colour is a surface stain, erosion, decay, or natural dentine showing through, and whether a professional cleaning or whitening assessment is appropriate.
