Oral and lip pigmentation treatment and safety
Dark areas on the lips or oral lining have several possible causes, so treatment depends on examination of the pigment and surrounding tissue.
The short answer
Lip or oral pigmentation is a change in melanin or other tissue colour that can be normal, medication-related, irritation-related, or associated with a lesion. A clinician should examine a new, changing, uneven, bleeding, or persistent patch before cosmetic treatment is considered.
Where can pigmentation appear inside the mouth?
Pigment may appear on the vermilion of the lip, inner cheek, gums, palate, or tongue. The history, distribution, surface texture, medications, tobacco exposure, trauma, and whether the colour is brown, blue, red, or mixed help guide the differential diagnosis.
How can you record changes in oral pigmentation?
Take a clear photograph for comparison, note when the change began, and list new medicines, cosmetics, tobacco exposure, or repeated biting. Avoid bleaching acids, unregulated lightening creams, and picking at the area while it is being assessed.
Which pigment changes need prompt dental assessment?
Arrange prompt evaluation for a patch that enlarges, changes colour or texture, ulcerates, bleeds, becomes painful, or has an irregular border. A specialist may recommend dermoscopy, imaging, or a biopsy when examination cannot identify the cause.
What should you ask about the pigmented area?
Ask what structure is pigmented, which causes fit the history, and whether observation, medical treatment, or biopsy is appropriate. If cosmetic removal is discussed, ask about recurrence, scarring, altered sensation, and who performs it.
Frequently asked questions
Can oral pigmentation be removed at home?
Do not apply bleaching or caustic products to oral tissue; first establish the cause with a clinician.
Does every dark spot need a biopsy?
No. The decision depends on examination findings, history, change over time, and the clinician's level of concern.
