Laser gum whitening
Laser gum depigmentation removes selected surface pigment from gingiva, but colour changes and recurrence depend on the tissue and cause.
The short answer
Laser gum whitening is cosmetic gum depigmentation, in which a dental laser removes pigmented surface tissue so lighter gingiva can heal beneath it. It changes visible pigmentation, not the natural anatomy of the gums or the colour of teeth.
What factors can influence the colour of your gums?
Gum colour is influenced by melanin-producing cells, tissue thickness, blood supply, inflammation, tobacco exposure, medicines, and some medical conditions. A clinician should identify the pattern before treating it because brown or dark areas are not always simple cosmetic pigmentation.
What happens during an assessment for laser gum whitening?
The dentist examines the gums, records the pigmentation, reviews medical and medication history, and discusses alternatives such as observation or non-laser depigmentation. After treatment, follow instructions for gentle cleaning, prescribed products, and avoiding irritants while the surface heals.
When does a dark gum patch need prompt dental assessment?
Have a dark patch assessed if it is new, uneven, changing, bleeding, ulcerated, painful, or associated with a lump. Seek review for delayed healing, worsening pain, pus, or swelling after a procedure.
What should you ask about laser gum whitening safety?
Ask what caused the pigmentation, whether examination or testing is needed, which laser and settings are proposed, and how the gums will be protected. Ask about healing care, possible colour variation, and alternatives if the pigment returns.
Frequently asked questions
Is laser gum whitening the same as tooth whitening?
No. Gum depigmentation targets gingival pigment, while tooth whitening acts on colour molecules within tooth structure.
Can dark gum colour return?
It can change again because pigment biology, irritation, tobacco, medicines, and the original cause may continue.
