Internal Bleaching

Internal bleaching procedures are performed on devitalized teeth that have undergone endodontic treatment but are discolored due to internal staining of the tooth structure by blood, fluids, or dental materials. Unlike external bleaching, which brightens teeth from the outside, internal bleaching brightens teeth from the inside out.  Bleaching the tooth internally involves placing a gel or paste into the pulp chamber after root canal treatment so it can work directly inside the tooth on the dentin layer.  The whitening agent is sealed within the tooth over a period of some days and replaced as needed until a satisfactory result is achieved.
