Why Are My Gums Black? What Causes Changes In Gum Color

Understanding the possible reasons for changes in gum color is essential since they might be alarming. There are several possible changes in gum color, yet it can be difficult to provide a definitive diagnosis. One of the most frequent reasons for gum discoloration is poor oral care, which can lead to plaque and tartar buildup and gum discoloration. Sometimes the chemicals in tobacco and smoking can cause the gums to turn black. This condition can also be another negative side effect of several drugs, including antimalarials and minocycline. In addition, underlying medical issues like gum disease or irregular melanin synthesis can be involved. Finding the precise reason and receiving the right advice for treatment and prevention need consulting a dentist.

Causes of Black Gums

Black gums can be caused by harmless lesions, smoking, dental treatment, medicine, and some medical conditions, including cancer. If these changes persist, they cause pain, bleeding, and other concerning symptoms and don’t go away on their own. You need to consult with a dentist to see what is going on and to find the proper treatment. Early intervention can often prevent complications and ensure your oral health. Further, we will talk about some of them:

Melanotic Macules

On the gums, benign black spots called melanotic macules might appear. They account for 86% of the dark lesions and are the most frequent source of dark pigmentation in the mouth. These lesions do not produce symptoms other than black patches. They might be grey, blue, black, or brown. An examination by a medical professional may include a biopsy to rule out cancer since melanotic macules resemble other illnesses that are risky.

Smoker’s Melanosis

Melanin can occasionally build up in the gums as a result of smoking. When this happens, it is referred to as “smoker’s melanosis.” It appears as a flat, black or brown patch on the gums. With 22% of smokers affected, the illness is common. Depending on the amount of smoking a person does, the probability increases. Smokers’ melanosis has no known cure, however, tissues usually change back to normal in six to 36 months after quitting. To rule out the possibility of cancer the doctor may perform a biopsy.

Amalgam Tattoos

When silver dental filling material settles into the gums during dental surgery, an amalgam tattoo develops. This causes a flat, black, or bluish-gray region of the gums that was most frequently present next to the tooth that underwent dental surgery. Dentists identify amalgam tattoos based on your dental history and outward look. On an X-ray, filling particles could also be visible.

Medications

Melanin pigmentation in the gums is a side effect of several medicines. These consist of:

  • Zidovudine (antiretroviral)
  • Chlorpromazine (antipsychotic)
  • Quinine (antiparasitic medicine)
  • Minocycline (antibiotic)
  • Chloroquine (antimalarial medication)
  • Ketoconazole (minocycline (antibiotic)
  • Bleomycin (chemotherapy drug)
  • Cyclophosphamide (chemotherapy drug)

Addison’s disease

An uncommon condition called Addison’s disease causes the body to generate insufficient amounts of the hormones cortisol and aldosterone. Adrenal gland dysfunction causes it. Abdominal discomfort, lightheadedness, exhaustion, and skin discoloration are some of the symptoms. Gums are one type of mucus membrane where skin darkening frequently happens. A person may get darker lips and gums as Addison’s disease worsens. Addison’s disease can also create darker patches of skin in other parts of the body besides affecting the lips and

Peutz-Jeghers Syndrome

An uncommon condition called Peutz-Jeghers syndrome (PJS)which happens because of a genetic mutation is characterized by the development of benign gastrointestinal growths. Additionally, the gums and the surrounding area of the mouth exhibit dark blue to dark brown freckling. 

Oral Malignant Melanoma

A kind of skin cancer called oral malignant melanoma grows in the mouth, especially on the gums. Oral melanomas are very unusual. This condition can initially be asymptomatic (without presenting any symptoms), but it can also exhibit changes in the color, symmetry, and form of the gums. Later, open sores, irregular bleeding, and mouth swelling might appear. Typically, they range from dark brown to bluish-black. White or skin-colored lesions, however, do rarely appear. A tissue biopsy is carried out by doctors to identify melanomas.

Symptoms of Black Gums

Black gums are often not a symptom of anything dangerous, but they can occasionally be an indication of oral cancer, so it’s vital to visit the dentist regularly to find out what is causing them. Among the signs of black gums are some of the following:

  • Bad breath
  • Dark stains on the surface of the teeth
  • Teeth beginning to lose 
  • Red, swollen gums
  • Bleeding gums

Gum disease may be present if you also have gum problems and black gums along your gum line. Your dentist may suggest using fluoride mouthwash and/or antimicrobial toothpaste to help reverse gum disease and maintain the health of your gums if it is still in its early stages.

Are There Tests to Diagnose the Cause of Black Gums?

If you notice a darkening of your gums that doesn’t improve, it’s important to consult a dentist. They will start by reviewing your medical history, medications, and any smoking or drug use since these can contribute to black gums. 

Next, the dentist will thoroughly examine your gums and teeth, checking for plaque, tartar buildup, and potential food accumulation between teeth using a periodontal device. If he notices any issue during the examination he will decide what the proper treatment for you is. X-rays and a biopsy may also be necessary in some cases for a more detailed understanding as this condition can also be a cause of cancer. Just like with any other condition early diagnosis and treatment are crucial.

Treatment

Each treatment will be different depending on the cause of the problem. Some conditions may need medication to be treated and sometimes they may go away on their own, for example, if it is caused by smoking. Gum bleaching is another possible treatment option offered by the dentist, even though it is not very highly recommended.

How to lighten dark gums at home

Normally, the safest thing to do if you start to notice any changes in your gums is to check with your doctor. Some people have tried using natural remedies like medical plants such as sage, mint, lemon balm, and oregano to treat this condition. Alternative medicine also suggests Thyme, calamus root, chamomile, and sage. This can help strengthen the gum tissues, get rid of bad breath, and reduce inflammation. Although this can work for some people no evidence supports these natural remedies. 

Professional black gum treatment

As we mentioned before there is a professional treatment done to improve the look of your gums. This procedure is called gum bleaching or depigmentation. There are two ways to create a new healthy smile. The first one is called microdermabrasion and the second is the laser technique. 

Microdermabrasion resembles the traditional way of whitening. Firstly the dentist will numb the gums and then the colored area will be removed. After this, the healthy, pink gums beneath will be revealed. This procedure takes only one hour to complete. 

A dental laser is used to target and destroy melanin-producing cells in the gums during laser depigmentation. Your body produces a naturally lighter gum color as the tissue heals. The good thing about this procedure is that the results are permanent and will last a lifetime.

Prevention

It is important to maintain good oral hygiene to keep your teeth and gums healthy. Flossing and brushing your teeth twice a day is essential. You may also consider cutting down the sugar use. Another thing you should consider is going to the dentist for regular check-ups as they can diagnose issues earlier and prevent further damage. 

Fluoride toothpaste will also protect your teeth and gums from damage. The dentists also recommend using a soft-bristled brush, to not cause harm to the gums and the tooth enamel. As we said before the risk of gum diseases, cavities, and plaque will be reduced if you maintain healthy habits. Most pharmacies and stores have dental floss, mouthwash, and other needed items for maintaining good oral health. It’s crucial to pick dental professional-recommended items that are specially made for your oral health requirements and to use them according to package instructions.
