Odontobleach is a sodium perborate-based endodontic bleach. Suitable for internal bleaching of stained teeth. Odontobleach is mixed with water in a dappens dish and blotted dry with a cotton roll. Odontobleach can then be picked up with an amalgam carrier and placed within a root canal and sealed. Repeated treatments may be required to remove the stain. Odontobleach is available in a 20 gram jar.
