This is another case of a gummy smile. The gum tissue covered up too much of the teeth, which caused the teeth to look short.
A crown lengthening procedure was performed, which evened the height of the gum tissue across the front teeth. What is interesting to see occur over time is the amount of increase in the smile that patients show after this procedure. After a few weeks, they are beaming since they no longer are insecure about their smile.
