Gummy Smile
Some people have very strong muscles that lift the upper lip so that, when they smile, the upper gums, rather than just the teeth, are visible.
Small amount of antiwrinkle treatments can reduce the ‘gummy smile’ appearance although patient selection is crucial.
Someone with a relatively long distance from under the nose to the top of the upper lip, would be less suited to this treatment as it tends to lengthen the skin above the upper lip.
