Gingival contouring is popularly known as gum reshaping and sculpting. This procedure has aesthetic and functional benefits. It helps to resolve the gummy smile problems and expose more of your natural tooth structure for dental restorations like crowns. The contouring procedure is conducted by sculpting your gums.
There are several reasons why your gum can appear too high or low. One of the most common reasons is gum recession, where your gum pulls back from the tooth, exposing more of your dental roots. While gingival contouring is mostly done for cosmetic purposes, it can also solve several problems, like exposing decays present deep within the tooth roots.
