Why do you have black gums?

There are several reasons why someone may have black gums, including:

Gum disease. This is the most common cause of black gums. When bacteria build up on the teeth and gums, it can cause inflammation and infection. This can lead to the gums becoming red, swollen, and bleeding. In severe cases, the gums can turn black.

Smoking. Smoking can damage the gums and cause them to turn black. This is because the nicotine in cigarettes constricts the blood vessels in the gums, which reduces the amount of oxygen and nutrients that reach them. This can cause the gums to become thin and weak, and they may eventually start to bleed and turn black.

Certain medications. Some medications, such as chemotherapy drugs and certain antibiotics, can cause the gums to turn black. This is because these medications can damage the cells in the gums and cause them to produce melanin, which is the pigment that gives skin and hair its color.

Medical conditions. Certain medical conditions, such as Addison's disease and Peutz-Jeghers syndrome, can also cause the gums to turn black. Addison's disease is a disorder of the adrenal glands, which can lead to a decrease in the production of the hormone cortisol. This can cause the gums to become dark and pigmented. Peutz-Jeghers syndrome is a genetic disorder that causes the formation of polyps in the digestive tract and dark spots on the skin and lips. It can also cause the gums to turn black.

Trauma. Injury to the gums can also cause them to turn black. This can happen if you accidentally cut or bite your gums, or if you have a tooth extracted. The blood that pools in the injured area can cause the gums to appear black.

If you have black gums, it is important to see a doctor or dentist to determine the cause. Treatment will depend on the underlying cause of the black gums.
