One of the most common causes of discoloured teeth is due to a 'dead tooth' or a tooth that is root filled. All of our teeth are supplied by nerve and blood supply. Now when a tooth needs a root canal treatment, this supply called the pulp is removed which can lead to the deposition of blood products within the tooth which is then absorbed by the tooth leading to a darker colour. On a back tooth, this may not have any major issue but on a front tooth is a different matter altogether!
How can you change the colour of a dark front tooth?

Case of the Month June 2025Our case of the month is a classic one of a dark front tooth after a childhood trauma will resulted in a root canal treatment. Over the years the tooth became darker and discoloured. We were asked three specific questions before treatment: 2. Can we improve the shapes of the teeth at the same time? 3. Can we close the spaces between the teeth? |

We can see here the left central tooth is discoloured and there is quite obvious asymmetry present in terms of widths, heights, spacing and gum levels.

After careful digital planning and tooth whitening, a crown was placed on the discoloured tooth and veneers on the adjacent teeth. He did not want a Hollywood white smile and asked for characterisation for a natural smile which was music to our ears.
What did the process involve and how long did it take?As alluded to above , the key aspect was the planning. Once we had our digital projection of the final outcome, we used this as our guide to the entire treatment. Tooth whitening is always the first step with internal and external whitening first. The only area where we had to prepare tooth structure to any degree was the dark tooth as we needed to block the brown shade. The adjacent teeth were micro preparations only. Provisional veneers were then placed using the projection and the our lab worked their magic. The fitting stage was next with a turnaround time of only two weeks.
