. Gingivectomy is the removal of gum tissue.
. Gingivoplasty is the reshaping of gums to improve functions, such as to prevent cavities or improve your ability to chew foods, or to change your appearance.
Gingivoplasty is less common as a treatment for gum disease, but may be done if your gums are affected by a genetic condition or as part of other dental procedures to restore tooth and gum function, especially as you lose gum definition and teeth over time.
