A gingivectomy involves the surgical removal of gum tissue. This procedure is typically performed to treat periodontal disease, where the gums have become inflamed or have excessive tissue, potentially interfering with oral hygiene or contributing to ongoing gum issues. By removing the affected gum tissue, the procedure helps in reducing pockets that can trap bacteria, thereby promoting healthier gum tissue and aiding in the overall health of the teeth and gums.

The other options relate to different dental procedures. Extraction of impacted teeth pertains to the removal of teeth that cannot properly emerge or are trapped within the jawbone or gums. Scaling and root planing is a non-surgical cleaning procedure aimed at removing plaque and tartar from teeth and smoothing the roots to encourage healing. Bone grafting involves transplanting bone to repair or rebuild bone in areas where it has been lost, which is not directly related to the management of gum tissue. Therefore, the focus of a gingivectomy is specifically on the surgical alteration of the gums themselves.
