Some patients are on medications that may make them photosensitive and the Zoom Whitening system advises against them using a light assisted bleaching system. This doesn’t rule out In Office rapid whitening for these patients.
We have used a number of in office whitening systems that do not require light activation. Most recently we having using Nupro White Gold In-Office Tooth Whitening System with great success. It seems as effective as the Zoom Whitening System and it does not require any light assistance! The set up is simpler and I have found that it requires about 15 minutes less time.
