Dark gums causes and treatment
Dark gums may reflect normal melanin, inflammation, medication, tobacco exposure, or a lesion, so treatment starts with finding the cause.
The short answer
Dark gums may reflect normal melanin, inflammation, medication, tobacco exposure, or a lesion, so treatment starts with finding the cause. Healthy gums can naturally vary from pink to brown, while a new or changing patch deserves examination.
What gives the gums their natural colour?
Gum colour is produced by blood vessels, epithelial thickness, and melanin in the mucosa. Diffuse, symmetrical pigment is different from a single irregular, raised, bleeding, ulcerated, or rapidly changing area.
What should you note about a changing dark gum patch?
Photograph a changing area in good light and note when it appeared, any new medicine, smoking or vaping exposure, and associated symptoms. Keep plaque controlled with gentle brushing and interdental cleaning, but do not scrub or chemically bleach the gums at home.
When does dark gum pigmentation need examination?
Book an examination for a new focal patch, asymmetry, bleeding, ulceration, pain, numbness, a lump, or colour change after trauma or medication. Urgent review is needed when swelling, fever, or difficulty swallowing accompanies the change.
How can the cause of dark gums be identified?
Ask whether the colour is physiologic pigmentation, inflammation, medication-related, tobacco-related, or a separate lesion. If it is benign and cosmetic, ask about observation, laser depigmentation, or surgical removal and how recurrence would be managed.
Frequently asked questions
Are dark gums always unhealthy?
No. Even pigmentation can be a normal feature, but new or changing pigment needs assessment.
Can smoking darken gums?
Tobacco exposure can stimulate darker oral pigmentation and also increases the need to assess gum health.
