Amalgam tattoo

Amalgam tattoo (also known as amalgam pigmentation) is a grey, blue or black area of discoloration on the mucous membranes of the mouth, typically the gums or inner cheeks, and less commonly the lips or tongue. It is caused by the introduction of dental amalgam into the soft tissues.

Causes

Amalgam tattoos are most commonly caused by a small piece of amalgam filling that has been embedded in the soft tissues during dental procedures. This can occur during the placement or removal of an amalgam filling, or during a tooth extraction. The amalgam can also be introduced into the tissues through wear and tear of the fillings over time.

Diagnosis

The diagnosis of an amalgam tattoo is usually made by a dentist or oral surgeon based on the characteristic appearance of the lesion and the patient's dental history. In some cases, a biopsy may be performed to confirm the diagnosis and rule out other conditions, such as melanoma.

Treatment

In most cases, no treatment is necessary for amalgam tattoos. They are not harmful and do not pose a risk to health. However, if the tattoo is causing cosmetic concerns, it can be removed surgically.
