Can baking soda remove the natural yellow colour of teeth?
Baking soda can loosen some surface stains, but it cannot bleach the natural color inside enamel or dentine.
How is sodium bicarbonate used in some toothpastes?
Sodium bicarbonate is a mild abrasive used in some toothpastes. Tooth color may also reflect dentine, enamel wear, calculus, decay, or intrinsic staining that brushing cannot remove.
How can a dentist identify the cause of yellow teeth?
A dentist distinguishes surface stain from internal discoloration and checks for decay, cracks, gum disease, fillings, crowns, and veneers before whitening.
What is safer than scrubbing teeth with loose baking soda?
Use fluoride toothpaste and gentle brushing rather than scrubbing loose powder onto teeth. Professional cleaning or peroxide whitening may be considered after the cause is identified.
What should you ask about discoloration and whitening?
Ask whether the discoloration is external or intrinsic and whether restorations will match after whitening.
