The short answer
A whitening toothpaste can remove some surface stain, but it cannot change the natural color of dentine or replace professional treatment for deeper discoloration.

How do whitening toothpaste ingredients affect surface stains?
Products marketed for whitening commonly use mild abrasives and sometimes peroxide. Abrasives polish extrinsic stain on enamel, while peroxide can chemically break down some color molecules.
How can you use whitening toothpaste safely at home?
Use a soft toothbrush with gentle pressure and follow the product label. If teeth are sensitive, alternate with a non-whitening fluoride toothpaste and have the cause of discoloration checked.
When should tooth discolouration be checked by a dentist?
See a dentist for one dark tooth, gray or brown internal discoloration, enamel defects, pain, or sensitivity that persists. A dentist can distinguish surface stain from decay, trauma, fluorosis, or medication-related color change.
What whitening option suits your restorations and sensitivity?
Ask whether the color is surface stain or internal discoloration, whether enamel wear or recession is present, and which whitening method fits your restorations and sensitivity.
