Gum darkening causes and evaluation
Dark gums may reflect natural melanin, smoking, medication, inflammation or a pigmented lesion, so a new or changing area needs examination.
Why do dark gums need assessment when they change?
Dark gums may reflect natural melanin, smoking, medication, inflammation or a pigmented lesion, so a new or changing area needs examination.
Why can healthy gums naturally range from pink to brown?
Gingival melanocytes produce melanin, so healthy gums range from pink to brown. A longstanding even pattern differs from a new, irregular, ulcerated or focal mark.
What details should you record about gum darkening?
Record when the change began and any tobacco exposure, new medicines, irritation or dental treatment. Do not scrape or apply bleaching chemicals; persistent unexplained lesions may need specialist review or biopsy.
When does a dark gum area need prompt review?
Arrange prompt care for a new, enlarging, uneven, ulcerated, bleeding or painful area, especially with a lump or failure to heal.
What should you ask about a pigmented gum area?
Ask whether the pattern appears physiological or acquired, what features require photographs or referral, and whether tissue sampling is indicated.
Frequently asked questions
What determines the right next step?
The examination finding, symptoms, anatomy and existing dental work determine the appropriate next step.
Can home care replace an examination?
Home care can support comfort and cleaning, but it cannot identify every cause or remove problems such as calculus, decay or a structural defect.
