How does dentist-provided overnight tray whitening work?
Philips Zoom Night is an at-home whitening approach using a dentist-provided tray and whitening gel worn according to the prescribed schedule.
How does the tray deliver gel to natural teeth?
The tray holds peroxide gel against natural tooth surfaces so the gel can diffuse into enamel and dentine. It does not whiten fillings, crowns, veneers, or bonding, and the product instructions and clinical plan determine wear time.
What should be checked before choosing a night tray?
A dentist checks for decay, gum disease, cracks, exposed roots, and existing restorations before making or selecting the tray. Use only the prescribed gel, keep it off the gums, and report sensitivity or irritation instead of extending wear time.
When should night whitening be reviewed by a dentist?
Arrange review before whitening if you have untreated dental disease, uneven darkening, gum bleeding, or significant sensitivity. Stop and seek advice for persistent pain, marked gum irritation, or a tray that cuts the tissue.
What should you ask about tray fit and restorations?
Ask whether the product is suitable for your teeth, how the tray should fit, how to handle sensitivity, and whether visible restorations will need separate colour planning.
