Why Are My Gums Black? Causes, Concerns and When to Seek Help

Feb 5, 2025

Introduction

Have you recently noticed black spots or dark patches on your gums? If so, it’s a case of concern, but don’t worry you’re not alone. Gum colour naturally varies from person to person, and over time, various factors can contribute to changes in gum colour. While it’s common for some people to have black gums because of genetics, sudden changes in gum colour to black may indicate underlying issues.

In this guide, we’ll explore common causes of black gums, why gums turn black and other related health concerns. We will also provide helpful tips for maintaining healthy gums.


What Does Black Gum Discoloration Mean?

Think about the range of skin tones we all have, gum colour also varies from person to person. Some people naturally have darker gums due to a higher level of melanin, which is especially common in people with darker skin tones. However, if your gums were once pink but suddenly turned black or have black spots on your gums, don’t overlook it.

These changes could indicate an underlying health issue that should be addressed promptly to prevent it from becoming more serious.

Understanding the causes of dark gums can help you identify whether they are harmless or a sign of a potential health concern.


Common Causes of Black Gums

Let’s look at the most common reasons why gums turn black.

  • Medications: Certain medications can cause dark spots or patches on gums. For instance, minocycline, an antibiotic prescribed for treating infections, is known to cause dark pigmentation in some people. This discolouration may resolve after stopping the medication.

  • Smoking: Smoking is one of the most common causes of black gum. The nicotine and tar present in tobacco can stain the gums over time; this condition is called a smoker’s melanosis, where gums appear dark or patchy.

  • Amalgam Tattoos: Imagine visiting a doctor to get a silver filling and noticing black spots on the gums near the teeth. These spots, called amalgam tattoos, are caused when the tiny particles from the filling embed themselves in the gum tissues. This may look like black spots on gums, but it’s harmless.

  • Natural Pigmentations: Similar to skin tones, gum colour also varies. Darker gum pigmentation is common in certain genetics and is completely normal and harmless.

Most of these factors are harmless and do not typically cause concern, but knowing the reasons why black gums are caused can help you determine whether they need attention.

Serious Conditions Linked to Black Gums

While black gums are often benign, there are some serious conditions to be aware of that may also cause gum discolouration:

  • Periodontal Disease: In advanced stages of gum disease, gum tissue can darken due to tissue death (necrosis). Periodontitis causes inflammation and infections of the gums, and when left untreated, it can lead to significant health diseases. 

  • Oral Melanoma: Though rare, oral melanoma is a type of mouth cancer affecting the soft tissues in the mouth and may appear as dark patches on gums. If you notice sudden dark spots on your gums, it’s better to get them checked.

  • Addison’s Disease: This is a rare adrenal gland disorder that causes dark pigmentions in various parts of the body, including gums. People with Addison’s disease may notice unusual dark spots on gums, lips, or inner cheek lining.

If you observe black spots on your gums or any new dark areas on your gums, it’s essential to assess whether these changes might be linked to severe health concerns.


How to Identify If Black Gums Are a Concern

After knowing why gums turn black the next step is to know if the reasons for dark gums are normal or if there’s a cause for concern. Look for these signs:

  • Sudden Change in Colour or Appearance: Imagine someone has pink gums all their life but suddenly notices black spots on gums or gums darkening. This could be a sign that something isn’t right and may need further observation and attention.

  • Presence of Other Symptoms: If black gums appear along with bleeding, tenderness, or swelling, it’s often a sign of infection or inflammation.

  • Spot Characteristics: If you notice black spots on gums that are irregular, growing, or changing in appearance, it’s best to consult a healthcare provider or dentist.


 When to Seek Professional Help for Black Gums

If you’re wondering when to see a dentist about black gums, here are some situations where it may be beneficial:

  • Unexpected Discoloration: Sudden, unexplained discolouration or blackening of your gums, especially without any prior causes like smoking, should be assessed by a doctor or dentist. They can help identify the cause of dark gums and recommend appropriate treatment options. 

  • Persistent or Growing Spots: Black spots on gums that don’t fade away with time or continue to increase in size should be a reason for concern.

Unusual growth of black spots on the gums may indicate underlying health issues, and seeking professional help is recommended.


Preventive Tips for Maintaining Healthy Gums

Maintaining a healthy lifestyle and good oral hygiene can reduce the risk of gum issues and keep the natural colour of gums. Here are some tips:

  • Brush and Floss Regularly: Daily brushing and flossing help prevent plaque buildup, which is one of the main reasons for gum disease. Good oral hygiene can also help you spot any changes in gum colour early on. Choose from Perfora’s electric toothbrushes and water flossers for quality oral care.
