The short answer
The most predictable way to whiten natural teeth is dentist-guided peroxide treatment after an examination, although a suitable regulated home product may work for some people.
What determines the colour of your natural teeth?
Tooth color comes from enamel translucency, dentin beneath it, and stains on the surface or within the tooth. Whitening products use peroxide chemistry to break down stain molecules, while fillings, crowns, and veneers do not change color.
How can a dentist help choose a suitable whitening option?
A dentist checks for decay, gum inflammation, cracks, exposed roots, and restorations before selecting custom trays, an in-office application, or a suitable home product. Follow the stated concentration and contact time, and stop if significant sensitivity or gum irritation occurs.
When should you have an examination before whitening?
Seek an examination before whitening if one tooth darkened, pain is present, gums bleed easily, or you are pregnant, breastfeeding, or under dental treatment. A dark tooth can need treatment rather than cosmetic bleaching.
What should you ask about stains, restorations, and sensitivity?
Ask what type of stain you have, whether existing restorations will mismatch, which peroxide method fits your teeth, and how sensitivity will be managed.
