How does peroxide affect enamel and dentine colour?

Whitening products use peroxide to oxidise colour molecules in enamel and dentine. They can lighten natural tooth structure, but they do not change the colour of fillings, crowns, veneers, or Lumineers, and some stains need diagnosis rather than more whitening.

How can you follow the product instructions safely?

Check the exact product instructions and use only the supplied amount and contact time. Have a dentist assess decay, cracks, gum recession, restorations, and existing sensitivity before whitening, and stop if significant pain or soft-tissue irritation develops.

Which whitening reactions require a dental assessment?

Seek dental care for persistent sensitivity, chemical burns to the gums, tooth pain, uneven colour, or a dark single tooth. Whitening should be postponed when untreated decay, leaking restorations, or inflamed gums need attention.

Is your Crest Professional formulation suitable for you?

Ask which Crest Professional formulation you have and whether it is suitable for your teeth. Ask how to protect exposed roots and gums, what result is realistic for your existing restorations, and what to do if sensitivity appears.
