What is the direct answer?
Baking powder is not a predictable tooth-whitening treatment because it is a variable mixture rather than a formulated dental bleaching product.
What does this question mean?
Whitening changes tooth colour by removing or breaking down stain molecules. Baking powder may abrade deposits or react in the mouth, but it does not provide the controlled peroxide chemistry used for dental whitening.
What can you do next?
Use fluoride toothpaste and have persistent discolouration assessed. A clinician can distinguish surface stain, natural dentine colour, fluorosis, trauma, decay, and restorations before selecting treatment.
When should you seek dental care?
Seek care before whitening if a tooth is painful, sensitive, chipped, dark after trauma, or visibly decayed.
What should you ask the dentist?
Ask whether the colour is surface or intrinsic, whether fillings will match afterward, and which method suits your enamel and gum condition.
