Philips zoom daywhite
Philips Zoom DayWhite is a dentist-directed take-home whitening system using custom trays and peroxide gel.
The short answer
Philips Zoom DayWhite is a take-home tooth-whitening system in which custom trays hold peroxide gel against the teeth for prescribed periods. The peroxide breaks down stain molecules within enamel and dentine, while the tray limits contact with the gums.

What is the direct answer?
What does this question mean?
DayWhite refers to whitening worn during the day, rather than an overnight tray routine. A dentist checks for decay, cracked teeth, leaking fillings, gum inflammation, and existing crowns or veneers because whitening changes natural teeth but not restorative materials.
What can you do next?
Have the teeth examined and obtain fitted trays if whitening is appropriate. Use only the prescribed gel amount and wear time, keep gel off the gingival margin, and stop and rinse if marked sensitivity or gum irritation develops.
When should you seek dental care?
Arrange an examination before whitening if a tooth hurts, bleeds around the gum, has a visible cavity, or has a dark single-tooth discoloration. Seek prompt care for swelling, spontaneous tooth pain, or irritation that persists after the trays are removed.
What should you ask the dentist?
Ask whether the discoloration is on the surface or inside the tooth, whether existing fillings or crowns will mismatch after whitening, and what gel concentration and wearing schedule fit your teeth. Also ask how sensitivity will be managed and when to stop treatment.
Frequently asked questions
Can whitening remove a cavity stain?
No. A cavity requires diagnosis and restorative treatment; whitening does not repair lost tooth structure.
Why can one tooth stay dark?
A single dark tooth may have internal discoloration from trauma, decay, or previous root-canal treatment and needs an examination before whitening.
