Philips zoom hydrogen peroxide
Philips Zoom whitening uses a peroxide gel to oxidize stain molecules, with the concentration and application controlled by the dental team.
The short answer
Philips Zoom whitening uses a peroxide gel to oxidize pigmented molecules in enamel and dentine; the exact gel, concentration, and light protocol depend on the treatment system.
What is hydrogen peroxide doing during whitening?
Hydrogen peroxide is the bleaching agent, and carbamide peroxide can release hydrogen peroxide as it breaks down. Whitening works through oxidation and is different from abrasive stain removal by ordinary toothpaste.
What should your dentist check before peroxide whitening?
A dentist should check for decay, leaking fillings, gum inflammation, cracks, and existing restorations before whitening. The team can select the gel and tray or in-office protocol, protect the gums, and explain how to manage temporary sensitivity.
When does pain after whitening need dental care?
Seek dental care before cosmetic whitening if a tooth hurts, has a cavity, or has a large restoration, and report severe or lingering pain after treatment. Gum burns, uneven colour, or a restoration that looks darker after whitening also warrant review.
What should you ask about peroxide and sensitivity?
Ask which Zoom system and peroxide formulation will be used, whether your restorations will match afterward, and how the gums and sensitivity will be managed. Ask whether a cleaning, filling, or replacement restoration should come first.
Frequently asked questions
Does a whitening light bleach teeth by itself?
The peroxide gel is the bleaching material; a light may be part of a specific system, but it does not replace the gel.
Why can teeth feel sensitive afterward?
Peroxide can temporarily affect fluid movement through dentine, especially where enamel is thin or roots are exposed.
