What leads to the appearance of black gums?

Are you hesitant to show off your smile because of the appearance of your gums? If your gums appear dark or black, it could be due to genetics, ethnicity, specific medications, diseases, or a more advanced stage of periodontal disease or gingivitis. Generally, dark gums aren’t painful, but they may cause discomfort or self-consciousness. However, if caused by periodontal disease or gingivitis, it can be painful and requires medical intervention.

While pink gums are the norm for most, just as no two fingerprints are identical, variations in gum color are also natural. Darker or black gums may result from a higher concentration of melanin or pigmentation imbalance. This condition is most often seen in individuals with darker skin tones but can affect anyone. Excessive sun exposure can darken melanin in both the skin and gums.

Certain diseases lead to an increase in melanin production. For instance, rare conditions like Addison's disease, the inherited disorder Peutz-Jeghers syndrome, and the bone condition Von Recklinghausen's disease can cause dark patches and discoloration that affect not only the gums but also other areas of the body.

Gum discoloration may also be triggered by smoking, medications like minocycline, antimalarial drugs, or tricyclic antidepressants, and even metal-based crowns or fillings.

If dark gums are causing you distress and you wish for a brighter smile, there’s good news – they can be treated. Surgical procedures can remove the dark layer to reveal the pink tissue beneath. Once healed, only a portion of the pigmentation returns, leaving behind lighter-colored gums.

Some dental professionals now offer a cosmetic bleaching procedure to lighten gums and enhance their appearance. This painless, in-office treatment permanently alters the melanin pigment, leaving gums looking pink and healthy.

Black gums can also indicate acute necrotizing periodontal disease, also known as black gum disease. The dark color is due to dead tissue or necrosis. Additional symptoms include spontaneous bleeding, rapid onset of pain, bad breath, and gum tissue that looks flattened between teeth, unlike the normal conical shape. Contributing factors include stress, poor nutrition, smoking, and viral infections like HIV. If untreated, this condition can spread to the cartilage and bone around the teeth.

Fortunately, this condition can be addressed with antibiotics or by surgically removing the affected tissue. Oxygen therapy, when combined with systemic antibiotics, can also aid in minimizing the damage to gum tissue caused by harmful bacteria.

Another condition that can darken the gums is acute necrotizing ulcerative gingivitis, which may lead to a grayish film on the gums. This disease, often referred to as 'trench mouth,' is caused by poor oral hygiene and was more common in the past. It gained the name because soldiers during World War I frequently developed it after long periods in the trenches without proper dental care.
