What is gum depigmentation?

The epithelium of gingiva contains cells called melanocytes. These cells are responsible for melanin pigmentation, which is seen as black spots or patches on the gum surface. Certain medicines, systemic diseases and habits like smoking can also cause gum depigmentation. Darkening of gums can also occur due to some gum diseases like ‘trench mouth’
Gum depigmentation, also called gum bleaching, is a cosmetic dental procedure performed to lighten and remove black spots and patches on the gum caused by melanin. 

Procedures used for gum depigmentation
Mainly 2 techniques are employed – laser and surgical

Laser : Dental laser targets melanocytes and ablates them, which in turn reduces the production of melanocytes. Similar to laser skin resurfacing, laser gum depigmentation destroys the top most layer of gums. This lightens the gums and gives them the natural pink colour. Treatment with laser ablation is minimally invasive and most effective. The healing time is speedy as well and patient discomfort is minimal.


In earlier days, surgical procedures were employed for gum lightening. Scalpels and rotary tools were used to physically abrade the gums. This method is more painful, more invasive and also more expensive.
Lasers are always superior to surgical depigmentation methods.

Before starting the treatment, your doctor may advice you deep cleaning and administer antibiotic drugs to rid off any persisting gum infections.
