What does it feel like?
Dark or black gums can reflect a change in oral pigmentation, but a new or changing dark area needs assessment rather than a visual diagnosis.
[1][2][3]What can cause it?
Smoking can affect oral tissues and is linked with oral health risks. Pigmentation and other tissue changes have different causes, so colour alone does not identify the diagnosis.
[3]What relief is safe tonight?
How is it checked?
A dentist or doctor examines the colour change and surrounding mouth. Persistent or suspicious changes may need further assessment to determine whether they are benign pigmentation or a disease-related lesion.
[3]What treatment depends on the cause?
Treatment depends on the diagnosis. Stopping smoking supports oral health, while a persistent lesion requires management recommended after examination. Cosmetic lightening should wait until a medical cause has been excluded.
[3]How can you reduce the chance of it returning?
Avoid tobacco and attend regular oral examinations. Protecting oral health also means reporting persistent sores, lumps, bleeding, numbness, or colour changes instead of waiting for them to disappear.
