A toenail falling off is usually not a major medical concern, but it can be painful and annoying. Toenails can fall off due to injuries, fungal infections, or psoriasis. In the case of an injury, blood may collect under the nail, known as a subungual hematoma, which can cause the nail to separate from the nail bed and fall off after several weeks. Depending on the cause and size of the lost toenail, it can take anywhere from six months to two years for the nail to completely grow back. During this time, it is important to keep the nail bed clean and protected to prevent infection.

What You'll Learn
Subungual hematoma
A subungual hematoma is a common injury that occurs when there is bleeding under a fingernail or toenail. It is usually the result of a crush injury, such as stubbing a toe or finger, and can cause intense pain and throbbing as blood collects under the nail. The pressure generated by the pooled blood can be extremely uncomfortable.
The treatment for a subungual hematoma depends on the severity of the injury. A small hematoma may not require medical treatment, and can be managed with ice, elevation, and over-the-counter anti-inflammatory medications such as aspirin or ibuprofen. However, if the hematoma covers more than a small portion of the nail, or if there is severe pain, it is important to seek medical attention. A doctor may perform a procedure called decompression or trephination, which involves creating a small hole in the nail to allow the blood to drain and relieve the pressure and pain. This procedure is typically done within the first 48 hours of the injury to prevent clotting, which can prolong pain. After trephination, it is important to keep the nail clean and dry, avoiding soaking it in water to prevent infection.
In some cases, especially if there is a fracture or damage to the nail bed or surrounding tissues, the nail may need to be removed and the nail bed repaired with stitches. A new fingernail can regrow in as little as 8 weeks, while a toenail may take up to 6 months to a year to fully regrow. During the recovery process, it is important to keep the nail bed clean and protected to prevent infection. This may involve keeping the area bandaged and wearing well-fitting shoes and socks to prevent further injury.
Overall, a subungual hematoma is a common and usually minor injury that can be managed with prompt medical care and proper wound care. However, it is important to be vigilant for any signs of infection, such as fever or feeling unwell, as this may require further medical attention and treatment.

Nail injuries and treatment
Nail injuries are common and can occur due to several reasons, such as car accidents, sports injuries, or dropping something heavy on your foot. Depending on the severity of the injury, you may be able to treat it at home, or you may need to seek medical attention.
Mild Nail Injuries:
For minor cuts or scrapes, gently wash the wound with soap and water. If there is any part of the nail that is hanging off, carefully trim it away. Keep the wound moist with petroleum jelly and cover it with a bandage or gauze. Change the dressing daily, and apply a small amount of antibiotic ointment if recommended by your healthcare provider. You can also take over-the-counter pain relievers, such as ibuprofen or acetaminophen, to manage pain and reduce swelling.
Severe Nail Injuries:
For more severe nail injuries, such as when the bone is broken or the bruise is very large, it is recommended to seek medical attention at an urgent care center or emergency room. The healthcare provider will assess the injury and determine the appropriate treatment. They may need to create a small hole in the nail to drain blood and relieve pressure and pain. In some cases, the nail may need to be removed, and the nail bed may need to be repaired with stitches or special glue. Antibiotics may be prescribed to prevent infection.
Preventing Nail Injuries:
To prevent nail injuries, it is important to keep your nails short and trim. Wear well-fitting shoes with a wide toe box to prevent rubbing, and always wear protective gear during sports or other activities that may pose a risk to your nails.
Recovery Time:
The time it takes for a nail to grow back can vary. A new fingernail typically takes about 4 to 6 months to grow, while a toenail can take up to 12 months or even longer, depending on the cause and size of the lost toenail. In some cases, it may take up to 2 years for the nail to completely regrow. During this time, it is important to keep the nail bed clean and protected to ensure proper healing.

Fungal infections
Fungal nail infections occur when the nail becomes thick, discoloured, and brittle. The infection usually starts at the edge of the nail and can spread to the rest of it, causing the nail to crumble and break easily. It can affect both toenails and fingernails, although toenail infections are more common.
Fungal nail infections are often not serious, but they can take a long time to treat and may require ongoing medication. Treatment options include antifungal creams, gels, sprays, nail polishes, and patches, which are available over the counter or online without a prescription. However, these treatments may not be strong enough for moderate or severe cases, and prescription drugs may be necessary. Oral antifungal medications are also an option, but they may not be suitable for individuals with certain conditions, such as liver or kidney disease, or for those who are pregnant or breastfeeding.
Home remedies, such as vinegar soaks, baking soda soaks or foot powders, Vicks VapoRub, or tea tree oil, can be used alongside prescription medications to help speed up results. However, it's important to note that home remedies alone may not be effective in treating fungal nail infections.
The timeline for treating a fungal nail infection can vary. Over-the-counter treatments may take months to show results, while prescription medications like terbinafine can take about 12 weeks to work. Even with successful treatment, it can take 12 to 18 months for fresh nail growth to fully replace the damaged nail.
To prevent fungal nail infections, it is recommended to keep your feet clean and dry, avoid walking barefoot in communal areas like showers and gyms, and wear shoes in locker rooms and other communal spaces.

Nail reattachment and regrowth
Once a nail has detached from its nail bed, it will not reattach. Instead, you will have to wait for a new nail to grow back, which can take anywhere from 6 months to 2 years, depending on the cause and size of the lost nail. Toenails, in particular, can take 12 months to 2 years to grow back, while fingernails typically take 4 to 6 months. Nails grow at a rate of about one-tenth of an inch per month, or 1 millimeter every 10 days.
While you wait for your nail to regrow, there are several steps you can take to promote nail growth and keep the area clean and protected:
- Keep your hands and feet clean, and your nails smooth and short.
- Apply a thin layer of petroleum jelly, such as Vaseline, and cover the area with a non-stick bandage.
- Take prescription pain relievers as directed by your doctor. You can also use over-the-counter medications like ibuprofen or naproxen to reduce pain and swelling.
- If you have diabetes, peripheral arterial disease, or a suppressed immune system, consult a podiatrist for advice on how to prevent infection and manage your nail regrowth.
- If you have an artificial nail, it should stay in place until your nail bed heals.
- If your nail is only partially detached, a physician may be able to repair the nail bed to prevent scarring.

Preventing nail loss
Nail injuries are quite common, and they can occur due to several reasons, from car accidents to dropping something on your foot. Toenails can take anywhere from a few months to two years to grow back, so it is important to take care of your nails and prevent nail loss. Here are some ways to prevent nail loss:
Keep Nails Short and Trimmed
Long nails are more prone to breaking and tearing, and bacteria can accumulate under them. Keeping your nails short and trimmed prevents them from catching on objects and pulling off your nail beds. Smooth and short nails also reduce your risk of losing a toenail.
Wash Your Hands Regularly
Washing your hands regularly helps prevent infections. Use a clean washcloth to reach beneath your nails. You can also use antifungal or antimicrobial soaks to prevent infections. These soaks may include ingredients like lemon juice, vinegar, hydrogen peroxide, and essential oils.
Choose the Right Shoes
Wear well-fitting shoes to prevent injuries to your toenails. Shoes that rub against your feet can cause blisters or sores that can get infected.
Wear Protective Gear
When playing sports, wear protective gear to shield your nails from potential injuries.
Avoid Biting Your Nails
Biting your nails can introduce cold-causing viruses into your mouth. It can also lead to punctures or tears in the skin, increasing the risk of ingrown nails or infections.
Dry Your Hands and Feet Thoroughly
Make sure to dry your hands and feet thoroughly after washing or showering. Bacteria and fungi thrive in moist environments, and waterlogged nails are more susceptible to splitting.
Treat Infections Promptly
If you notice any signs of infection, such as discolouration, pain, inflammation, or pus, consult a dermatologist. Infections can worsen if left untreated, especially if trapped under nail polish.
