Melanocytes are cells which reside in the basal layer of the gingival epithelium. These cells produce melanin, which are pigments that cause discoloration or dark spots in gums. A dental laser can target and ablate the melanocytes, thus reducing the production of melanin in the gingival tissue. Following laser depigmentation, the gingiva heals by secondary intention. This results in a lighter and more uniform colour of the gums.


A frenectomy (also known as a frenulectomy or frenotomy) is the removal of a frenulum, a small fold of tissue that prevents an organ in the body from moving too far. It can refer to frenula in several places on tahe human body. It is related to frenuloplasty, a surgical alteration in a frenulum. Done mostly for orthodontic purposes, a frenectomy is either performed inside the middle of upper lip, which is called labial frenectomy, or under the tongue, called lingual frenectomy. Frenectomy is a very common dental procedure that is performed on infants,[1] children, and adults. A similar procedure frenulotomy is where a tight frenulum may be relieved by making an incision in the tight tissue.
