Gummy smile treatment: hyaluronic acid filler vs botox
Part of Mouth & dental clinical trials.
This study compares two treatments for a gummy smile (when too much gum shows when you smile) caused by a hypermobile upper lip. It tests whether a hyaluronic acid filler or botox injections work better to reduce gum display.
