One Dark Front Tooth - Options?

In the modern world of technology, we have many options of getting the right shade.Digital shade matching gives us the ability to conquer the trickiest shade challenges all day, every day, instantly and accurately. Also the dentist can have the lab tech come in personally to get you the right shade for your discolored tooth.Since you are getting root canal treatment on that tooth, the most ideal option is to put a full coverage crown on that tooth. The reason being first and foremost the tooth is discolored and also after the root canal treatment the tooth itself is not very strong and full coverage will protect it from further breakdown. You could also do veneer but root canal treated teeth usually get darker as time passes and you might need to replace your restoration.

When a tooth is traumatized and the nerve damaged, the tooth may darken due to death of the nerve.  A root canal therapy is your only option.  Sometimes, an internal bleaching procedure can be done after root canal therapy to lighten the tooth.  When internal bleaching is not enough, a crown or porcelain veneer is indicated to mask the discoloration.  You indicated this was an upper central incisor, the focal point of the smile.  Under these circumstances, I would recommend doing the same procedure, crown or veneer, on both upper central incisors to provide an aesthetic match.
