Bread soda for teeth whitening
Baking soda may remove surface stain, but it does not bleach internal tooth color and can irritate enamel or gums when misused.
The short answer
Baking soda may remove some surface staining through mild abrasion, but it does not bleach the internal color of teeth and can irritate enamel or gums if misused.

What is baking soda and where is it used in dentistry?
Baking soda is sodium bicarbonate, an alkaline powder used in some formulated toothpastes. Its cleaning action is mainly mechanical on surface deposits, while bleaching products use peroxide chemistry to change some internal tooth stains.
How can you clean teeth without scrubbing loose powder?
Use a fluoride toothpaste and a soft brush for routine cleaning instead of scrubbing with loose powder. A dentist can check enamel wear, exposed root surfaces, cavities, fillings, crowns, and the cause of discoloration before selecting whitening.
When do sensitivity or discolouration need dental care?
Seek care for painful sensitivity, gum burning, rough enamel, or discoloration that does not improve with cleaning. A dental examination is also appropriate before whitening if you have untreated decay or gum inflammation.
How can a dentist identify the cause of tooth colour?
Ask whether the color is surface stain, tooth-internal discoloration, or a restoration that whitening will not change. Ask which product strength, contact time, and sensitivity plan suit your teeth.
Frequently asked questions
Will baking soda whiten a filling?
No. Tooth-colored fillings and crowns keep their material color while natural tooth structure may change with whitening.
What should I use instead?
A fluoride toothpaste made for regular use and a dentist-selected whitening method address cleaning and color change more predictably.
