Why Do Gums Turn Dark — and How Does Laser Gum Bleaching Help?

When gums appear dark or discoloured, it’s often due to excess pigmentation — primarily melanin — within the gum tissue. Certain areas may accumulate more pigment, causing a grey, brown, or “black” look, especially in contrast with lighter surrounding gums.

Laser gum bleaching (or depigmentation) works by gently removing the pigmented surface tissue and targeting the cells that produce melanin. Here’s how it transforms dark gums into a pinker appearance:

Surface removal
The laser removes the top, pigmented layer of gum tissue where most of the dark pigment lies.
Destruction of pigment-producing cells
The energy from the laser helps suppress or neutralise the melanocytes (cells that create pigment) in the treated area.
New, lighter tissue regeneration
As the site heals, healthy gum tissue grows back — tissue with little to no pigmentation — resulting in a more naturally pink gum colour.

Curious to see if your gums are good candidates for bleaching — and to estimate how much lightening is possible?
