text: In relation to carcinogenesis, high hydrogen peroxide concentrations may act as a promoter of oral lesions together with other known carcinogenic products (tobacco, alcohol), but low concentrations of carbamide peroxide are considered to be safe, and some recommendations should be directed to patients and clinicians, such as to protect the oral soft tissues when applying high HP concentration agents (in office bleaching), to use low concentration agents and for short periods of time.6 Care should also be taken to avoid deglutition of peroxide agents.
