In this article, the authors identify the cause of tooth staining under the influence of external factors – pigments acting on the hard tissues of the tooth when eating. Experimentally, with the help of eight different reagents, the degree of staining of tooth enamel was assessed over the time of primary exposure during the day, and then a week. After that, the authors carried out bleaching using toothpastes and mouthwashes. The results obtained are presented in a table reflecting the coloring power of eight reagents in descending order. The conclusion is made about the resistance of tooth enamel to the procedure of home bleaching
