The short answer
Smoking can leave brown or yellow surface stain on enamel, and whitening toothpaste mainly helps remove this external discoloration.
How does tobacco smoke create yellow or brown tooth stain?
Tobacco smoke deposits pigments and can promote plaque accumulation. Abrasive toothpaste may polish away some surface stain, but it cannot change the color of fillings, crowns, veneers, or stain located within the tooth.
How can you use toothpaste without worsening tooth wear?
Use a fluoride toothpaste as directed, brush gently with a soft brush, and avoid scrubbing harder to chase stain. A dental cleaning can remove hardened deposits, while professional whitening is considered only after the teeth and gums are examined.
When could tooth discolouration need a dentist’s review?
See a dentist for a new, one-sided, rough, or persistent discoloration, bleeding gums, ulcers, or a sore that does not heal. Mention tobacco use so the examination includes the gums and oral lining.
What should you ask about stain removal and whitening?
Ask whether the stain is external or internal, whether a cleaning is needed, and how existing restorations will compare after whitening. Ask what brushing method is appropriate for your enamel and gums.
