I present you with a dental case dealing with traumatic injury causing discoloration of the teeth and how the issue was resolved. The patient has a history of trauma to her two teeth in the front. As a result the teeth have died off and become darkly stained. They had a root canal to prevent teeth from getting darker or infected.
The first step is to choose a shade or “colour” to match the crowns to. Once we agree on a suitable colour the teeth are “prepped”. Basically the teeth are prepped to allow an adequate amount of material for the crown. I crown acts like a hat or jacket for the tooth. As you can see in the photo below the teeth look like stumps when they are prepared. I also take a shade of the prepped tooth or “stump shade”. This is important because the porcelain is glasslike and lets light through, the final crown shade is a combination of the white crown and the yellow tooth.
