Fingernail injuries are common and can result from a variety of incidents, such as smashing a finger in a door or cutting it with a knife. These injuries can cause the nail to fall off, and the time it takes for this to happen depends on the severity of the injury. In some cases, the nail may fall off immediately, while in others, it may take several weeks or months for the nail to detach completely. During this time, it is important to care for the wound properly to prevent infection and ensure the nail regrows healthily.

Factors that affect how long a fingernail takes to fall off
Fingernails usually take about two months to regrow completely, while toenails take about four months. However, several factors can affect how long it takes for a fingernail to fall off after an injury. Here are some key factors to consider:
Type and Severity of Injury
The type and severity of the injury play a crucial role in determining how long it takes for a fingernail to fall off. Minor injuries, such as a small bruise or crack, may only require basic wound care and will have a shorter recovery time. On the other hand, more serious injuries like deep tears or injuries involving the nail bed or matrix may take longer to heal and could result in permanent cosmetic changes. In some cases, medical intervention, such as stitches or antibiotics, may be necessary, prolonging the recovery process.
Presence of Infection
Infection is a common complication of nail injuries. If the nail bed becomes infected, a doctor may need to perform a procedure called nail evulsion to forcibly remove the nail. This can delay the natural process of the nail falling off and may require additional treatment to address the infection.
Underlying Health Conditions
Certain underlying health conditions can impact the healing process and, consequently, the time it takes for a fingernail to fall off. For example, individuals with diabetes, peripheral arterial disease, or immune system problems may experience reduced blood flow and loss of feeling in the affected area, slowing down the healing process.
Treatment Approach
The approach to treating the injury can also influence the timeline for the fingernail to fall off. In some cases, a doctor may attempt to reattach the nail or use a special material to protect the nail bed during healing. These interventions can delay the natural process of the nail falling off as the body heals and regenerates the nail.
Nail Care Practices
Proper nail care after an injury is essential for optimal healing. Keeping the nail bed clean, dry, and protected with a bandage or petroleum jelly can promote healing and reduce the risk of infection. Trimming the nail if it is partially detached can also prevent further tearing and potential complications.
It's important to note that the information provided assumes proper medical care and wound management. Seeking medical attention and following the advice of a healthcare professional are crucial for ensuring the best possible outcome and recovery.

What to do if there is a lot of blood under the nail
A collection of blood under the nail is called a subungual hematoma. This happens when blood collects between the nail and the nail bed, causing throbbing pain. If there is a lot of blood under your nail, you should seek medical attention. A doctor may perform a procedure called decompression or trephination, which allows the underlying blood to drain, relieving pressure and pain in the area.
If you are unable to see a doctor, there are a few at-home treatments you can try. One method is to heat a needle or the end of a paper clip until it is red-hot, then use gentle pressure to penetrate the nail, creating a small hole for the blood to drain. However, it is important to note that this method may not be comfortable or safe for everyone. Alternatively, you can try basic wound care:
- Put pressure on the area to slow the bleeding.
- Clean the wound with soap and water.
- Apply a bandage.
- Take an analgesic to help with pain if needed.
- Ice your finger if you have swelling in the area.
If you have a large subungual hematoma, your nail will likely fall off on its own after several weeks. A new fingernail can regrow in as little as 8 weeks, but it may take up to 4 to 6 months for the nail to fully replace the lost nail. Toenails can take even longer, up to 12 months. The new nail may have grooves or ridges and be somewhat misshapen.

How to treat a fingernail injury at home
Fingernail injuries are very common and can happen due to several reasons, from closing a car door on your fingers to kitchen accidents or sports injuries. Depending on the type and seriousness of the injury, you may be able to care for a fingernail injury at home. Here are some detailed steps you can take to treat a fingernail injury at home:
Stop the Bleeding
If there is bleeding, use a clean cloth to apply direct pressure to the wound. This will help to slow down the bleeding.
Clean the Wound
Once the bleeding has stopped, gently clean the wound with soap and warm water to prevent infection. Ensure that you clean not only the wound but also the torn nail area if there is one.
Apply Medication
Apply a small amount of petroleum jelly to the wound to keep it moist. You can also apply antibiotic ointment to prevent infection and promote healing.
Bandage the Wound
Cover the wound with a bandage or gauze to keep it protected. Make sure to only apply sticky products, such as an adhesive bandage, to the skin around the nail to avoid irritating the injury. Change the bandage daily while the wound heals.
Elevate the Injured Area
Prop the injured finger or toe on pillows so that the nail is higher than your heart. This will help to reduce swelling and promote healing.
Take Pain Relievers
If you are experiencing pain, you can take over-the-counter pain medications such as acetaminophen (Tylenol or Advil) or ibuprofen (Advil, Aleve) to help relieve pain and reduce swelling.
Apply a Cold Compress
Use a cold compress or ice pack to the injured area to further reduce swelling and provide relief.
It is important to note that if you cannot bend your finger or toe, if there is blood covering more than half of your nail, if your nail is black or purple, or if the injury is particularly painful, it is best to seek medical attention from a dermatologist or urgent care centre.
If you lose your fingernail due to the injury, it will take about 7 to 10 days for the nail bed to heal. A new fingernail will typically take about 4 to 6 months to grow back, and it may have grooves or ridges and be somewhat misshapen.

How to care for the nail bed after a fingernail falls off
Fingernails falling off is often a result of trauma or injury to the nail. It can be very painful to tear or rip a nail from its nail bed. After the nail falls off, it is important to care for the nail bed to prevent infection and promote healing. Here are some ways to care for the nail bed after a fingernail falls off:
Clean the wound
It is important to clean the wound to prevent infection. Gently wash any minor cuts or scrapes with soap and water. You can also apply a small amount of antibiotic ointment to the wound to prevent infection and keep any dressing from sticking.
Cover the nail bed
Apply a bandage or adhesive tape to the nail bed to protect the sensitive skin. Leaving the nail bed exposed can cause it to become very dry and cracked, which can affect how the nail grows back. Keep the wound covered until it has healed and a new nail has started to grow.
Control swelling and pain
Apply ice wrapped in a cloth to the injured area for 20 minutes every 2 hours on the first day, then reduce to 3 to 4 times a day after that. This will help to reduce any swelling and throbbing pain. Over-the-counter pain medications such as ibuprofen or acetaminophen can also be taken to manage pain.
Keep the area dry
Keep the nail bed area dry to prevent infection. A new nail will eventually grow in and replace the old nail, pushing it off as it grows. This process can take about 4 to 6 months for a fingernail and up to 12 to 18 months for a toenail.
Avoid certain products and chemicals
Avoid using nail products or chemicals that can irritate the nail bed or the skin surrounding it. This includes nail polish, nail gloss, nail hardener, nail polish remover, and fake nails. These products can damage the nail bed and hinder the healing process.
Keep nails trimmed and avoid biting
Keep your nails trimmed and short to prevent them from catching on objects and pulling off the nail bed. Avoid biting your nails as this can also cause trauma to the nails and hinder the healing process.
It is important to follow the recommendations of your healthcare provider when caring for a wound or injury. With proper care, the nail bed will heal, and a new nail will grow back over time.
