What is the direct answer?
Toothpaste with baking soda can help remove some surface stains, but it cannot change every type of tooth discoloration.
What does this question mean?
It does not bleach the internal tooth color, and it cannot whiten fillings, crowns, veneers, or other restorations.
What can you do next?
Use a soft brush and a toothpaste formulated for teeth rather than repeatedly rubbing loose powder onto the teeth. A dentist can identify whether discoloration is surface stain, enamel change, decay, medication-related, or a restoration before whitening.
When should you seek dental care?
Seek dental care for a dark spot, pain, sensitivity, a rough surface, or discoloration limited to one tooth. Arrange an assessment before whitening if you have cavities, gum disease, enamel erosion, exposed roots, or extensive restorations.
What should you ask the dentist?
Ask what type of stain you have and whether baking-soda toothpaste, professional bleaching, cleaning, or restoration replacement fits it. Ask how to reduce abrasion and how existing fillings or crowns will look after natural teeth are whitened.
