Internal tooth bleaching is a procedure designed to remove stains from the inside of the tooth. After the nerve and any infection have been removed, and the root canal has been cleaned, sealed and filled, internal tooth bleaching can be performed.
Internal tooth bleaching involves the insertion of a peroxide gel into the clean, empty pulp chamber. This allows the gel to work directly inside the tooth on the dentin layer. The internal bleaching gel produces the same effect as external bleaching agents, but it simply works on the stains inside of the tooth that can’t be reached by external means.
