You are in the right place. Dr. Tom Biernacki, DPM, FACFAS — board-certified foot & ankle surgeon with 3,000+ surgeries — explains exactly what black toenail falling off means and what actually works. Call (810) 206-1402 for a same-day appointment at our Howell or Bloomfield Township office.
Quick answer:A black toenail is usually a bruise — blood trapped under the nail from injury or tight shoes — that loosens and grows out over several months. Because a dark nail can rarely be melanoma, have a podiatrist check any black nail that appears without an injury or keeps changing. Call (810) 206-1402.

What Does a Black Toenail Falling Off Mean?
A black toenail typically forms when blood collects under the nail (subungual hematoma) or when the nail becomes damaged due to trauma, pressure, infection, or circulation problems. As the nail loses its attachment, it may loosen or fall off entirely.
While some cases heal on their own, others require medical attention to prevent infection, deformity, or permanent nail damage.

What Causes Your Toenail to Turn Black and Fall Off?
Why are my toenails turning black and falling off?
- The toenail becomes black because the underside of the toenail plate is very rich with blood vessels.
- Once the nail is disturbed and loosened, these blood vessels rupture, leading to blood pooling.
- The blood will stop eventually, but increased pain can increase due to increased pressure underneath the nail.

When a Black Toenail Is Dangerous: Melanoma Warning Signs
Most black toenails are harmless bruising. Rarely, a dark nail is a subungual melanoma — a skin cancer under the nail that is often mistaken for a bruise that won’t heal. See a podiatrist promptly if any of these apply:
- The dark color appeared with no injury you can remember.
- It isn’t growing out with the nail over 2–3 months (a bruise moves toward the tip; melanoma tends to stay put or widen).
- A single dark band runs lengthwise down the nail and is getting wider or darker.
- The pigment extends onto the skin of the cuticle or nail fold (Hutchinson’s sign).
- One nail is dark, doesn’t match the others, or is changing, cracking, or bleeding without trauma.
These signs don’t mean you have cancer — most won’t — but they warrant a same-week evaluation. A podiatrist can date a bruise, examine the nail, and biopsy if there’s any doubt. Early detection changes outcomes. Call (810) 206-1402.
Will the Toenail Grow Back?
- In almost all cases, the toenail will grow back.
- The undersurface of the nail plate is needed to nourish it with blood, but the nail will regrow from the base of the nail.
- So if you lose the last 5 millimeters of your toenail, it will take approximately 5 months for it to grow back.
- It isn’t easy to increase the speed of regrowth.
- The most you can do to regrow your nail is to decrease the pain and swelling when it happens and protect the toe.
The occurrence of a black toenail falling off is usually due to three common causes:
- Trauma or Injury – A stubbed toe, dropped object, or repetitive pressure from tight shoes or athletic activity can cause bleeding under the nail, turning it black and eventually causing it to detach.
- Fungal Nail Infection – Infections can darken and thicken the nail, weaken its attachment to the nail bed, and lead to nail loss if left untreated.
- Circulation or Health-Related Issues – Poor blood flow, diabetes, or other medical conditions can weaken the nail, make it more prone to injury, and result in discoloration or detachment.

Best Toenail Fungus Products:
- These are our favorite products to treat toenail fungus at home.
- Keratin Granulations are very easily taken care of through moisturizing your nails with cuticle wax, oils and simply avoiding nail polish for a little while.
- It is not necessary to buy anything expensive or online; it is fine to use a product like Vaseline or any other petroleum oil in most circumstances.
- So get yourself some petroleum jelly at your corner store and apply it to your nails at night when you won’t be using your hands. In 2 weeks, you should be in great shape!
- Make sure you read the reviews and see if it is good for you!
How to fix toenail fungus:
- There are many different types of toenail damage.
- In our experience, about 90% or more is related to toenail fungus.
- The key to toenail fungus is to trim it as much as possible and file that nailed down.
- These products are not meant to replace prescription drugs or medical treatment equipment.
- If you can do that, you have to make sure you can kill fungus the rest of the way.
- The best way to do that is to soak exfoliate the affected toenail skin. So, consider foot soaks.
- At the same time, you have to apply antifungal medication such as these medications recommended here or the toenail repair pens.
Best Toenail Fungus Clippers & Files:
- This is something you have to be careful using at home, and deftly don’t use these if you have dangerous health conditions.
- These are some great value heavy-duty clippers and sets.
- The key is to cut straight across and file the nail down from the top to prevent impinging in the corners.
- It is also important to make sure all dead, dry skin is removed surrounding the foot.
- This is where you should really see your podiatrist if you have any concerns or are worried about cutting or hurting yourself.
- This is something covered, so don’t take chances with your health!
Best Antifungal Moisture Wicking Socks:
- These are some great options for moisture-wicking socks.
- We tried to focus on budget value stocks that are not too expensive.
- Sure there are better stocks out there, but these are great socks for a great price for most people.
- If you have diabetes, focus on getting yourself some diabetic socks.

Recommended foot fungus products:
- It is also essential to fix your foot fungus.
- Even if you cure your toenail fungus, keep your toenails trimmed in healthy: your foot fungus can spread back into toenails.
- It’s not a far journey from skin fungus to jump onto your toenails again.
- So make sure you treat your foot fungus, as well as your toenail fungus.
Get The Best Shoes:
- You definitely want to get great shoes and sandals for your toenail fungus and foot fungus.
- Specifically, when you are in a communal shower or pool, you want to get a good pair of sandals. We compiled a great list of our recommended orthotic flip-flops.
- You also want to get new breathable shoes that are not covered in sweat and mesh around the toes.
- Specifically, good pairs of running shoes have a mesh where your toes are. This prevents your toenails from rubbing and prevents them from dreaming on the front of the foot.
