Whitening cream teeth
A tooth-whitening cream may remove some external stain through its ingredients, but it cannot reliably change the internal colour of every tooth.
The short answer
Creams and toothpastes act mainly on the exposed enamel surface. Abrasive particles can lift deposits, while peroxide-containing products may affect some colour molecules; neither approach changes the shade of fillings, crowns, veneers, or the underlying cause of a grey or brown tooth.
How should whitening cream be used safely?
Check the ingredient label, use only the amount and frequency directed, and brush with a soft brush without pressing hard. Have persistent discolouration, sensitivity, enamel wear, gum recession, or visible restorations assessed before choosing a whitening method.
When should you stop using whitening cream?
See a dentist if one tooth changes colour, whitening causes pain, the gum becomes sore, or the surface looks thinner or rougher. An examination is also appropriate before whitening when decay or enamel defects may be present.
When does tooth colour need a dental examination?
Ask whether the colour is surface stain, enamel change, dentine colour, or a restoration. Ask which method matches that cause and how to avoid abrasion or sensitivity.
What could be causing the tooth colour change?
Surface stain and internal tooth colour are different problems.
Frequently asked questions
It depends on the product and the cause of discolouration. A cream may address surface deposits, while supervised bleaching is a separate treatment for selected natural teeth.
