This tip was developed in order to help clinicians not only to focus on composite shade selections but also the importance of contours and finishing which are crucial components to creating a natural appearing esthetic restoration.
The tip attempts to emphasize that there are general guidelines to accepted tooth contours as well as variations to the guidelines.
However, especially when trying to restore a tooth adjacent to a natural tooth, we must match the contours and level of finishing to that natural tooth in order to make it blend-in and disappear. A very pertinent example would be over polishing a restoration which would not blend-in well if the native enamel of the adjacent natural tooth does not exhibit the same degree of smoothness.
