What is internal bleaching (Walking Bleach)?

Incorrect root treatments, traumas or dead nerves are the number 1 cause for a change in the colouring of a tooth. Due to internal bleaching the tooth can be brightened with the help of hydrogen peroxide.

However, we only perform internal bleaching if the root filling is free from inflammation. We remove part of the root-filling material to eventually seal the canals. The cavity is then filled with a bleaching agent. The cavity is then sealed. Five to seven days later we check the result. Should the treated tooth still be dark, we will repeat the process during a different appointment. Generally speaking a total of three appointments is needed in most cases. If the desired colour of the tooth has been achieved, we neutralise the bleaching reaction. We seal the tooth with a plastic filling or a dental prosthesis. This depends on the situation. The result achieved will remain the same for many years to come.
