The repair to the affected tooth is completely natural looking. Notice that the tooth is not a uniform color or translucency. When Dr. Perry uses dental bonding to repair gaps or chips, he must exactly match the colors and translucency of all parts of the tooth he is repairing. The composite material must be shaped properly, then polished to match the surrounding teeth.
This is very demanding work, artistically, and few dentists have the skills and aesthetic sense necessary to do this kind of beautiful work.
