What are the Causes of Black Gums?

There are a variety of reasons for black gums and in most cases, the cause is not serious.  For example, amalgam tattoos are dark spots that may form around fillings, dentures, and crowns. This issue often looks like a blue or black tattoo in the mouth, and though it is not desirable to those seeking a perfect smile, it is also harmless. Of course, amalgam tattoos can be removed by a dentist if preferred. 

Calculus, which is a substance that can build up in the mouth when oral hygiene is lacking, can also cause dark areas on the gums.

Black gums may also be a symptom of acute necrotizing periodontal disease, also known as black gum disease. The black coloration is a result of dead tissue, or necrosis.

Black gums may also be a sign of malignant melanoma in the mouth, which is particularly difficult to treat. The good news is that dark gums can typically be avoided through sufficient oral hygiene that includes regular brushing, flossing, dental checkups, and avoidance of smoking and chewing tobacco. 

If you have black gums, it is best to be evaluated by a dentist to rule out the possibility of a serious cause.  Feel free to contact our office for an oral evaluation by Scottsdale dentist, Dr. Brian Williams.
