All Philips Zoom! whitening products including in-office, take-home custom and take-home semi-custom trays are proven safe on enamel without compromising the whitening effectiveness
Some people may experience temporary tooth sensitivity during treatment. However, all Philips Zoom! products are designed to prevent tooth sensitivity caused by whitening. Based on surveys, customers experience little-to-no teeth sensitivity123
We recommend choosing a whitening solution based on desired time-to-result and convenience:
The main difference is in wear times. Philips Zoom! DayWhite uses various percentage HP formulations that are faster and require a wear time of 30-90 minutes per day. Philips Zoom! NiteWhite products use CP formulations, act relatively slower and need to be worn 2-4 hours per day or overnight.
If you have a history of allergic reactions, consult your dentist before you use the whitening products.
Yes. Some dental treatments start with an in‑office session for fast, noticeable change and follow with take‑home trays (custom or semi‑custom) for gradual maintenance and touch‑ups. Discuss the treatment plan with your dentist.
Most professionals advise women not to whiten their teeth during pregnancy and breastfeeding.
Yes, but whitening gels do not work on restorations. Expect restorations to remain in the same shade. Consult your dentist about restorations.
After whitening treatment, your teeth may never be as dark as they were. However, they may still become slightly discolored over time, especially if you smoke or consume pigmented foods. For this reason, some people opt for a touch-up treatment once or twice a year. Talk to your dentist about the available options.
