Did you know that the use of bleaching agents increases dental enamel permeability?

Vol.12 no.2 of Brazilian Journal of Oral Sciences includes "Evaluation of human enamel permeability exposed to bleaching agents" by Horning et al. This study evaluated various bleaching techniques to find out how different bleaching techniques affected dental permeability. A dye was used to show the degree of penetration on human teeth of four groups; Group 1 did not use a bleaching agent, while the other groups used 35% hydrogen peroxide for various numbers of 10 minute applications.
