Dark or Black Gums: Causes and Gum Depigmentation
Written & medically reviewed by Dr. Rajat Shaikh, MDS — Pediatric & Preventive Dentistry · Last updated July 2026
Dark or black gums are usually caused by natural excess melanin and are harmless — laser gum depigmentation can safely lighten them for a pinker, more even smile.
Many people are self-conscious about dark gums showing when they smile. The good news is it is usually harmless and treatable.
Why are my gums dark?
The most common cause is extra melanin (the natural pigment in skin and gums) — often simply genetic. Smoking and certain medicines can also darken gums.
Is it harmful?
Melanin pigmentation itself is harmless. However, if a dark patch is new, changing or one-sided, it should be checked to rule out other causes.
How does laser gum depigmentation work?
A dental laser gently removes the thin pigmented surface layer of the gum, revealing pinker tissue underneath. It is precise, minimally invasive and part of our cosmetic dentistry care.
What to expect
Treatment is quick with minimal discomfort and short healing. Results are usually long-lasting, though pigment can slowly return in some people.
