Maintaining gums in good condition is very important for our oral health and aesthetics since its function is to hold the teeth in place.

An alarming sign a priori, is the darkening of the gums. The causes of black gums can be diverse, but do not panic, most are not harmful to health.

Healthy gums

The gums are made of hard, fibrous and sensitive tissue. They serve as a junction between the teeth and the alveolar bone.

They usually have a pinkish appearance, but sometimes they develop black or dark brown spots, although in most cases, as we will see, they represent a more aesthetic than a health problem .

Sometimes, however, blackheads can indicate a more serious condition . To be sure, it is best to deal with your dentist if you notice the appearance of dark spots on the gums, especially if they are also painful or change in size, shape or color.

The solution to black gums will depend directly on the cause that causes it.

Possible causes of black gums

The reasons for the gums turning black can be of different nature. By maintaining proper oral hygiene, we minimize the risk of associated diseases .

Mouth injuries

The gums can be injured like any other part of your body . Falling flat on your face, eating something with sharp edges, and even brushing or flossing your teeth too hard can damage your gums. Gum bruises are usually dark red or purple, but they can also be dark brown or black.

These injuries usually heal on their own without the need for medical treatment. If with the passage of time the hematoma does not remit, it is advisable to consult a dentist.

Rash bruises

This cyst can sometimes be made up of blood mixed with fluid, which can make it look dark purple or black. When an eruption cyst has blood in it, it is called an erupting hematoma.

They usually go away on their own after the tooth comes in . If the tooth does not come out on its own, the dentist can surgically open the cyst to allow the tooth to come out properly.

Amalgam tattoos

Another cause that can create black spots on the gum are the so-called amalgam tattoos. When filling a cavity with a silver amalgam filling , a deposit of this amalgam may remain on the gums, creating a dark spot.

Amalgam tattoos cannot be removed, but they are harmless and require no treatment.

Blue nevus

A blue nevus is a harmless mole that is round and flat or slightly raised. Blue nevi can appear black or blue and generally look like a freckle on the gums.

The cause of blue nevi is unknown, but they often develop during childhood or adolescence and are more common in women.

They usually do not need treatment. However, if its shape, color or size begin to change, the dentist can perform a biopsy, removing a part of the nevus to analyze it, ruling out the possibility of cancer.

Oral cancer

Cancer inside the mouth can also cause black gums. Other symptoms associated with oral cancer include open sores, unusual bleeding, and swelling in the mouth.

To determine if a spot is caused by cancer, the dentist will perform a biopsy and use different imaging techniques , such as a CT scan, to check if the cancer has spread.

If the spot is cancerous, it can be surgically removed if it has not spread. If it has spread, radiation therapy or chemotherapy can help kill cancer cells.

Drinking large amounts of alcohol and using tobacco are the greatest risk factors for developing oral cancer.
