Black Gums Around Teeth: Causes
Dark gums may reflect normal melanin pigmentation, smoking, medication, inflammation, or a localized lesion requiring assessment.
The short answer
Gum colour varies naturally because melanocytes produce melanin in the gingival tissue, but a dentist should assess new, asymmetric, raised, bleeding, or changing pigmentation. The clinician records location, size, colour, surface texture, duration, and changes, then reviews smoking, medicines, trauma, restorations, and medical history.
How will a dentist assess a dark area on the gums?
The clinician records location, size, colour, surface texture, duration, and changes, then reviews smoking, medicines, trauma, restorations, and medical history. A persistent unexplained lesion may need specialist assessment or biopsy.
How should you protect dark gums before assessment?
Do not scrape, bleach, or apply household chemicals to the gums. Photographing a changing area with a date can help the clinician compare its appearance.
When should black gum pigmentation be examined?
Book an examination for a new, enlarging, irregular, painful, ulcerated, bleeding, or raised dark area. Prompt review is especially important when the change is confined to one site.
What should you ask about a dark gum area?
Ask whether the colour is diffuse pigmentation or a focal lesion, what may have caused it, and whether monitoring, treatment, or specialist assessment is needed.
Frequently asked questions
Are dark gums always a disease?
No. Natural pigmentation is common, but appearance alone cannot diagnose the cause of a new change.
Can dark gums be lightened?
Cosmetic depigmentation may be considered only after the cause is assessed and the gum tissue is healthy.
