Dark or black gums aren't always a warning sign. Natural pigmentation is common, especially in darker skin tones, and doesn't require treatment.

Smoking is one of the most common causes of darker gums. Quitting can gradually reduce smokers' melanosis.

Poor oral hygiene and gum disease can darken gum tissue, turning it red, purple, brown, or even grey or black in severe cases. Early treatment prevents further damage.

You might notice dark gums one morning while brushing your teeth and feel a spark of worry. Why are my gums black? Is something wrong? Most people jump straight to the worst conclusion, but dark or black gums aren’t always a problem. They can be completely natural, or they can be your gums quietly signalling that something needs attention. 

Pigmentation, smoking, medication, and gum disease all play a role. Some causes are harmless, some aren’t, and knowing the difference matters. We’ll walk through all the reasons why your gums might be turning black, how to get rid of black gums, and which treatments actually work.

Common causes of dark or black gums

Dark gums have many faces. Sometimes it's your biology, while other times, it's a habit that's been sneaking up on you for years. Occasionally, it's medical. Here's where the real detective work begins.

Natural pigmentation

Many gums are naturally dark. High melanin levels are completely normal, especially in people with darker skin tones. In this case, dark gums aren't a symptom of poor hygiene or disease. They're simply part of you; harmless and unchanging. If the gum colour hasn't changed suddenly, natural pigmentation could be the entire answer to the question: why are my gums black?

Smoker's melanosis

Smoking doesn't only stain teeth. It also triggers an increase in melanin production in the gum tissue, causing gum discoloration. Over time, the gums may appear patchy, brown, black, or smoky-looking. The body is reacting to cigarette smoke by increasing pigmentation. Luckily, stopping smoking often allows the colour to fade gradually, not overnight, but slowly.

Poor oral hygiene and gum disease

Maintaining your oral hygiene is essential to ensure your teeth stay healthy. If one fails to maintain good oral hygiene, plaque builds up, irritates the tissue, and inflammation takes over. If gum disease progresses, your gums may not only darken but also recede, bleed, or hurt. In severe cases, where tissue becomes damaged or necrotic, you might even see grey or black patches. That's never normal and shouldn't be ignored. Sometimes people wonder, “Why are their gums turning black?” The answer often links back to infection, trauma, or deep decay.

Amalgam tattoos

It sounds dramatic, but it's not. When a dentist uses older-style silver fillings, tiny pieces can drift into the gum tissue. They leave a permanent, harmless dark spot known as an amalgam tattoo. These don't change shape or size. They just sit there quietly, often mistaken for disease.

Medications

Certain antibiotics, antimalarials, birth control pills, or even antipsychotic medicines may create gum hyperpigmentation. It's a side effect that isn't dangerous, though sometimes it's visually noticeable. If your gums started darkening after beginning a new medication, tell your doctor or dentist. It may be reversible or at least manageable.

Endocrine conditions

This cause is rare but important. Disorders like Addison's disease can create dark patches on the gums and inner cheeks. The darkening happens because hormone issues increase internal pigmentation signals.

Other medical causes

Occasionally, dark gums point to concerns like circulatory disorders, anaemia, or even oral cancer. This doesn't happen often, but sudden colour changes or black gums appearing without a clear cause are worth checking quickly.

Treatment options for dark or black gums

Not all gum discoloration needs treatment. But when it does, the right option depends on the cause. Some treatments brighten the gums for cosmetic reasons. Others restore health.

Professional dental cleaning

Dark gums caused by plaque or early gum inflammation can often improve with a thorough cleaning. Scaling and root planing remove the irritants responsible for redness, swelling, and darkened tissue. It's simple. Often, the first step and surprisingly effective for people whose gums are going black due to inflammation rather than pigmentation.

Gum depigmentation

Some people want lighter gums purely for aesthetics. Gum depigmentation lifts excess melanin from the surface. Dentists can do this using:

  • Laser depigmentation

  • Cryosurgery (freezing techniques)

  • Scalpel removal of the top pigmented layer

Laser is the most modern and popular choice because healing is quick and results are smooth. People searching for how to get rid of black gums often choose this treatment.

The outcome depends on your natural pigmentation, but many patients see noticeably lighter gums.

Treating underlying conditions

If medication is causing the colour change, your clinician might adjust it. If a systemic disease is behind it, managing that condition becomes the priority. The gums often brighten on their own once the root issue settles.

Managing gum disease

Early gum disease can be reversed. Brushing, flossing, professional cleanings, antimicrobial rinses, and improved habits can restore pinkness and reduce darker patches. More advanced gum disease might need deep cleanings or specialist care. And in severe cases, the priority is preventing bone loss and infection rather than just lightening gum colour.

Prevention tips to keep gum colour healthy

Healthy gums come down to consistent habits. Not complicated ones. Just the basics you've heard your whole life, plus a few extras.

Practice strong oral hygiene

Brush twice a day using fluoride toothpaste. It keeps plaque under control and prevents the irritation that leads to discoloured gums. Floss daily. Even on the days you're tired, especially on those days.

Visit your dentist regularly

Routine check-ups catch inflammation early before gums turn dark or painful. Cleaning appointments lift stubborn tartar and keep gum colour steady.

Avoid tobacco products

Stopping smoking not only helps your lungs. It reduces smokers' melanosis, improves gum health, enhances breath quality, and prevents gum tissue breakdown.

Use an antimicrobial mouthwash

Rinses with antibacterial properties help prevent plaque accumulation, inflammation, and the darkening caused by chronic irritation.

Monitor medication effects

If you notice changes after starting a new prescription, tell your doctor. It might be harmless, but it helps to note these things early.

When to see a dentist urgently

Even though dark gums can be normal, there are warning signs that you shouldn't ignore.

  • Gum patches that appear suddenly

  • Gums turning grey or black around a painful tooth

  • Persistent bleeding or swelling

  • A spot that changes shape, grows, or feels unusual

  • Pain or lumps that don't make sense

  • A black patch near a tooth with an old filling

Dark gums can be natural

Dark or black gums don't automatically mean something is wrong. So, are black gums normal? Many people naturally have darker pigmentation. Others develop changes due to habits, medications, or gum disease. What matters is knowing whether your gums are simply unique or trying to warn you.

With better hygiene, lifestyle adjustments, professional cleanings, or treatments like gum depigmentation, you can enhance your gum colour and overall oral health. If anything feels unfamiliar, or you're unsure why your gums are discoloured, a quick consultation helps settle the worry. Healthy gums aren't just about colour. They're about comfort, confidence, and long-term wellness, all things worth protecting.

Frequently asked questions

faqs
It depends on the cause. If it's natural pigmentation, you might not need treatment at all. For cosmetic improvement, gum depigmentation is most effective. If gum disease is the cause, scaling, root planing, and improved oral care are essential.
Advanced gum disease, Addison's disease, certain circulatory conditions, and rare oral cancers may darken the gums. Sudden colour changes should always be checked.
Gums may appear dark, greyish, swollen, or receding. There may be bleeding, pain, or a foul smell. In severe cases, tissue damage can create black or dying areas.
Sometimes. Smoker's melanosis can fade after quitting smoking. Inflammation-related darkness improves with treatment. Natural pigmentation stays unless you choose cosmetic lightening.
Not always. It can be hereditary or natural. But it can also be a sign of infection, irritation, or systemic health issues.
