Gum bleaching or Gum depigmentation is a procedure used in cosmetic dentistry to remove black spots or patches on the gums caused by excessive melanin.
The normal color of the gum tissue (gingiva) is pink, but excess deposits of melanin (melanin gingival hyperpigmentation) can create what seem to be black spots or patches on the gums, creating an aesthetic or cosmetic problem. Discoloration may also be caused by long term use of certain medications or smoking.
A clinical assessment is carried out to customize the treatment to the patient needs, and the procedure itself can involve surgical, chemical, or laser ablation techniques.
Laser Gum Depigmentation Techniques (Laser Gum Bleaching)
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 color of the gums. This procedure is painless and the result is immediate.
