Cam whitening toothpaste containing bleach be good for the teeth?

Yes: When included in therapeutic amounts it is efficacious and not harmful. Amount is equivalent to the amount found in tap water to thwart water-borne bacterial pathogens. If it was harmful, FDA would prevent sale. Do know, however, that whitening t’pastes tend to be more abrasive and only remove surface stain.
