When cleaning the pulpal (nerve) area of a tooth during a root canal procedure, sodium hypochlorite (a strong base - pH 11 and more commonly known as bleach) is usually used in concentrations between 0.5 and 5.25%. The overall effect is to dissolve organic tissues that can not be readily accessed mechanically.

Dental Did You Know: Tooth Bleaching Using 10% carbamide peroxide and Enamel Hardness
In a recent study, it was shown that bleaching teeth with 10% carbamide peroxide can reduce enamel surface microhardness. It was recommended by the authors to either add professionally administered or self-administered fluoride to remineralize the enamel.
