White beauty teeth whitening
Professional whitening lightens natural tooth colour by breaking down stains, while fillings, crowns, and veneers do not bleach.
The short answer
Teeth whitening uses a peroxide gel to break down stain molecules in natural enamel and dentine. A dental examination should come first because whitening does not change the colour of fillings, crowns, or veneers.
What is the direct answer?
What does this question mean?
The phrase refers to cosmetic bleaching, not a separate type of tooth. Darkening may come from coffee, tea, tobacco, plaque, ageing, enamel thinning, or staining inside a tooth after injury or root canal treatment.
What can you do next?
A clinician checks for decay, leaking restorations, gum disease, cracks, and the cause of discolouration before selecting an in-office gel or custom trays for home use. Follow the prescribed wear time and stop if marked sensitivity or gum irritation develops.
When should you seek dental care?
Seek an examination before bleaching if one tooth is suddenly dark, painful, chipped, or sensitive, or if the gums bleed or appear inflamed. A dark tooth may need treatment rather than cosmetic whitening.
What should you ask the dentist?
Ask whether the colour is from surface stain, internal discolouration, or disease, and which teeth will respond. Confirm how existing restorations will look after whitening and how sensitivity will be managed.
Frequently asked questions
Will whitening make every tooth the same colour?
Not necessarily. Existing fillings, crowns, and veneers retain their original shade, and internal stains may respond differently from surface stains.
Can I whiten teeth with untreated decay?
The decay should be examined and treated first because peroxide can aggravate sensitivity and whitening does not repair the damaged tooth.
