A specific brand of in-office teeth whitening system (by Philips) that uses a high-intensity Blue LED light to activate a hydrogen peroxide gel.
It is fast. In a single 45-minute session, teeth can become up to 8 shades whiter. It is more effective than any take-home strip.
A light-activated power bleaching session done by a dentist.
Results fade over 1–2 years depending on diet. Touch-up trays can extend this indefinitely.
It can cause temporary sensitivity to cold air for 12–24 hours. It does not damage the tooth.
