While not all teeth discolour following root treatment it is reasonable to expect some slight alteration in colour of the tooth following root canal treatment, particularly where a front tooth is involved. Colour change may be already present due to a number of factors including amalgam fillings or trauma. Post treatment discolouration may be caused by the root filling materials in the visible portion of the tooth. All steps are taken to try and reduce the chances of this happening. It is also important to note that discolouration following trauma may take months or even years to develop.

If the discoloration proves to be a problem, there are a number of procedures which can be undertaken to improve the colour and appearance dependent on the type and severity of the discolouration. These include Internal Bleaching, Veneers and Crowns.
