Is teeth whitening harmful?

Teeth Whitening is Safe
Teeth whitening with professional peroxide is a safe and effective way to enhance your smile. The effects of dentist administered whitening every 6 months followed by at home whitening over the course of many years has not been scientifically studied. The studies I have looked at show no significant change to the enamel 1 month after professional whitening. I have patients that are frequent users of teeth whitening gel that have seen no problems with tooth strength, so it is probably ok to whiten frequently. To increase enamel strength, I always have my patients alternate use of bleaching gel with a mineral paste to strengthen and rebuild enamel.
