It is a procedure used to whiten teeth which have been discolored mainly due to a root canal treatment or trauma. Internal bleaching is recommended when the color changes originate in the pulp.
How does it work?
It consists of opening the tooth and insertion of an oxidizing chemical substance into the tooth’s pulp. If the first amount inserted did not succeed in whitening the tooth properly, the bleaching gel can be replaced in a few days.
The internal bleaching gel has the same effect as the external bleaching products, but it acts from inside of the tooth. The procedure can be performed alone or with external whitening procedures.
