The short answer
A tooth stain is removed according to its location: surface pigment may need professional cleaning, while colour inside enamel or dentin may need whitening or another treatment.

How can a tooth stain be removed safely?
The correct method depends on whether the discoloration is on the surface or within the tooth.
What causes stains on the enamel surface?
Extrinsic stains sit on enamel and can come from tea, coffee, tobacco, chromogenic plaque, or calculus. Intrinsic discoloration lies within tooth structure and may follow trauma, development, medication exposure, or loss of pulp vitality.
How can you care for stained teeth at home?
Brush twice daily with a fluoride toothpaste, clean between the teeth, and avoid scraping the surface with sharp objects or abrasive household powders. A dental hygienist can remove calculus and polished deposits, after which a dentist can judge whether bleaching, bonding, or a veneer is appropriate.
When should a tooth stain be examined?
Book an examination when one tooth changes colour, the stain returns quickly, the tooth is painful, or the gum bleeds around it. A grey or dark tooth after an injury may require pulp testing and an X-ray.
What should you ask about tooth discolouration?
Ask whether the discoloration is external or internal, whether cleaning alone can remove it, and whether decay, enamel wear, or a non-vital pulp is involved. Ask how any restoration will match after whitening.
Frequently asked questions
Does whitening remove calculus?
No. Calculus is hardened mineralized plaque and generally needs professional instrumentation.
Why is one dark tooth different?
A single dark tooth can reflect trauma, pulp changes, or a restoration, so it needs an individual assessment.
Will a filling whiten?
No. Whitening changes natural tooth structure, so a visible filling may need replacement later for shade matching.
