Just as we have our own unique skin tone, the gum also has its own tone. The
pigment melanin is responsible for the colour of the gums.
People with darker gums have more melanin pigment in them. Here are some
of the causes for gum darkening
Usually addressing the cause of the pigmentation is sufficient – for example if
it is due to cigarette smoking, cessation of the habit can improve the gums,
or changing the medications too. The dental treatment with Lasers involves
using Laser beam to target the top layer of cells of the gums that contain the
melanin pigment. With this layer gone, the pink gums underneath are
revealed and most patients get satisfactory results.
