What are Those Black Dots Under Nails? Here’s What You Need to Know

Have you ever noticed tiny black dots under your nails and wondered what they were? While these spots may seem harmless, they could actually be a sign of an underlying health condition. In this blog post, we’ll explore the various causes of those mysterious black dots under nails and what you need to know about them. From nail trauma to melanoma, we’ll cover it all so that you can take the necessary steps to protect your health and keep your nails looking their best. 

What are Black Dots Under Nails?

There are a few different things that can cause black dots under nails. The most common is simple over-growth of the nail plate, which can be caused by bacteria or fungal overgrowth. Over-growth can lead to thickened nails and black spots on the nail surface. Other causes of black dots include melanoma, which is a cancerous tumor in the skin, and pyogenic granuloma, which is an infection of the nail bed.

If you think you may have any of these conditions, it’s important to consult a doctor to get a diagnosis and treatment plan. In many cases, simply treating the over-growth or infection will resolve the issue with black dots. If that doesn’t work, your doctor may recommend surgery to remove the affected nail tissue.

What Causes Black Dots?

Black dots are caused by a fungal infection. The fungus grows underneath the nails and produces these black dots. This infection is usually treated with an over-the-counter antifungal cream or oral medication. If left untreated, the fungus can spread to other parts of the body, such as the lungs, and cause serious health problems.

How to Remove Black Dots Safely

There are a few causes of black dots, but the most common is nail growth. As your nails grow, they push against the quick, which can cause black spots below the nails. Other causes include bad cuticles or fungus on the fingernails.

If you notice black dots under your nails, you should see your doctor to rule out any medical conditions. If the dots are caused by nail growth, there is little you can do to remove them yourself. However, if the dots are caused by other factors, there are a few ways to remove them safely and effectively:

-Apply a thin layer of clear nail polish over the black spots. This will hide the spots and prevent them from spreading.

-File away the black spots using a gentle file until they disappear completely. Be sure not to scratch the skin underneath the nails! Read more…

-Apply a topcoat made for nails to protect them from further damage and keep the polish looking fresh.


If you are scratching the black dots under nails and seeing black dots underneath them, there is a good chance that you have dermatitis pyoderma progressive (DPP), also known as nail-pitting disease. DPP is an extremely rare condition that affects the skin beneath the nails and causes them to become thin, brittle, and discolored. Left untreated, DPP can cause the nails to fall off entirely. If you think you may have DPP, it is important to consult a doctor as soon as possible for a diagnosis and treatment plan.
