Abstract:

Tooth bleaching is the application of bleaching agents that mitigate tooth discoloration caused by a disease, aging, food and beverage staining, and smoking. Conventional bleaching agents mainly produce reactive oxygen species from hydrogen peroxide, which undergoes a redox reaction that converts organic pigment molecules into light-colored compounds. However, the bleaching effect of hydrogen peroxide needs to be improved, and the bleaching process may increase tooth sensitivity and cause enamel demineralization. Nevertheless, research on how to mitigate these effects with dental bleaching agents have advanced in recent years, and this paper reviews components with non-peroxide bleaching efficacy, novel methods for hydrogen peroxide catalysis, and strategies for mitigating the adverse reactions of bleaching.

Key words: tooth bleaching agent, photocatalyst, pulp stimulation
