Extensive research and clinical studies indicate that whitening teeth under the supervision of a dentist is safe. In fact many dentists consider whitening the safest cosmetic dental procedure available.
A clinical study performed by Loma Linda University on the effect of whitening gel on tooth enamel, confirmed that Zoom! is safe. The study concluded that Zoom! ?does not adversely affect the microhardness and surface morphology of human enamel.?
A clinical study was conducted by Discus Dental to evaluate the efficacy of the Zoom! system. Fifty subjects participated in a study that showed that the average shade change with the Zoom! system is 8 shades and that the Zoom! system is ?safe and effective for whitening teeth rapidly.? In addition, minimal sensitivity was noted during the study, with a significant number of patients reporting no sensitivity.
