Baking soda can make teeth white
Baking soda can remove some surface stain by mild abrasion, but it does not bleach the internal colour of teeth.
The short answer
Baking soda can make teeth look cleaner by removing some surface stain, but it does not bleach the internal colour of teeth.
How can sodium bicarbonate lift deposits from enamel?
Sodium bicarbonate is a fine abrasive that can help lift deposits on the outer enamel surface. It cannot change the colour of dentine beneath enamel, and it cannot whiten crowns, veneers, or fillings.
How should you clean teeth without scrubbing with powder?
Use fluoride toothpaste and a soft brush for daily cleaning rather than scrubbing teeth with loose powder. A dentist can distinguish surface stain from internal discolouration and discuss professional whitening after checking enamel, decay, gums, and restorations.
Which colour or gum changes should a dentist assess?
Seek care for sensitivity, worn or translucent enamel, bleeding gums, persistent darkening, or a single tooth that changes colour. Do not use abrasive methods to mask pain or a suspected cavity.
Is the tooth colour suitable for professional whitening?
Ask whether the colour is surface stain, enamel change, or dentine discolouration, and whether whitening is appropriate for your teeth. Ask how existing restorations will look after natural teeth are lightened.
