Before You Try Baking Soda
Baking soda may remove surface stains, but repeated use can wear exposed tooth surfaces and raise sensitivity. Learn safer limits and when to see a dentist.
The short answer
Baking soda is not automatically harmful, but repeated abrasive brushing, especially on exposed root dentin, can wear tooth surfaces and increase sensitivity.

What can baking soda remove without rebuilding enamel?
Sodium bicarbonate is a fine alkaline powder that can help detach some surface deposits, but it contains no fluoride and does not rebuild enamel. Damage risk depends on pressure, frequency, brush stiffness, the product's abrasivity, and whether enamel or dentin is exposed.
How can you brush safely instead of using loose powder?
Use a soft brush, light pressure, and a fluoride toothpaste made for daily use instead of relying on loose powder. Do not mix baking soda with lemon juice or other acids, which can chemically soften enamel.
When should sensitivity or tooth-surface changes be examined?
Seek an examination for sensitivity, cupping, flattened edges, recession, grooves near the gumline, or a change in tooth colour. Pain or a visible defect may indicate decay, erosion, abrasion, or a crack.
Could your symptoms reflect abrasion, erosion, or decay?
Ask whether your symptoms reflect abrasion, erosion, attrition, recession, or decay. Ask for a low-abrasion fluoride product and a brushing technique that protects exposed surfaces.
Frequently asked questions
Can baking soda repair enamel?
No. It can clean some surface stain, but it cannot replace lost enamel or fill a cavity.
Why are my teeth sensitive after scrubbing?
Forceful brushing can expose dentin through gum recession or surface wear, allowing temperature changes to stimulate the tooth's nerve pathway.
