Yes dark gums can be treated by the gums de-pigmentation procedure. They are safely lighten to the classic pink color. Gum de-pigmentation, also known as gum bleaching, is a procedure to lighten or remove black spots or patches on the gums consisting of melanin pigment. The procedure takes 20-45 minutes depending on the color and size of the dark patch. We will give you local anesthetic to make the procedure as comfortable as possible. This is a very common procedure which is done routinely in our clinic. With the coming of lasers the procedure has become bloodless and painless and heals up quickly.
