A damaged nail bed can take anywhere from a few weeks to several months to heal, depending on the severity of the injury and the effectiveness of the treatment provided. In most cases, new nails will slowly regrow, but this process can be slow and may vary depending on the severity of the injury. Proper treatment can help ensure that the nail bed heals appropriately, forming a smooth surface for the new nail to grow. Minor nail bed injuries often heal on their own, but more severe injuries may require medical attention and take longer to heal. During the healing process, it is important to follow healthcare providers' advice on wound care, pain management, and physical therapy to promote optimal healing.

Healing time depends on the severity of the injury and treatment
The healing time for a nail bed injury depends on the severity of the injury and the treatment received. A nail bed injury can occur when a heavy object crushes or hits the fingers or toes, resulting in blood under the nail, known as a subungual hematoma. Nails can also be torn, split, or lifted away from the nail bed due to trauma. Repeated trauma to toenails, such as from ill-fitting shoes, can lead to deformities, while habits like nail biting can cause acute paronychia, an infection characterized by swelling and irritation.
Mild to moderate nail bed injuries typically take several weeks to a few months to heal, while severe injuries may take up to six months or longer. During the healing process, it is crucial to follow the healthcare provider's advice on wound care, pain management, and physical therapy to promote optimal healing. In some cases, minor nail bed injuries may heal on their own without requiring medical intervention.
The treatment for a nail bed injury depends on the severity of the trauma. For instance, if there is bleeding under the nail, a physician should be consulted to evaluate for potential bone fractures or tissue tears. In the case of a severe subungual hematoma, a doctor may perform trephination by making a small hole in the nail to drain the pooled blood. If the nail is damaged or torn, the doctor may remove it and repair the nail bed. Stitches may be used to repair any lacerations to the nail bed, and the nail may be reattached to provide protection during the regrowth process.
The regrowth of nails after an injury can take several weeks to a few months, depending on whether it is a fingernail or toenail. Fingernails typically regrow completely in about two months, while toenails can take up to four months. In cases of severe nail matrix damage, some or all of the nail may not grow back, resulting in permanent cosmetic changes. However, with proper care and attention, a functional and healthy nail is attainable in most cases.

Home remedies and medical treatments are available
The healing time for a nail bed injury depends on the type and severity of the injury. Minor nail bed injuries often heal on their own without any treatment, while more severe injuries may require medical attention and take longer to heal. Here are some home remedies and medical treatments for nail bed injuries:
Home Remedies:
- Keep your nails moisturized by applying oil or serum daily to help them heal faster and become stronger.
- Eat foods rich in vitamins A, B, C, and E, such as olive oil, eggs, carrots, sweet potatoes, spinach, kale, milk, strawberries, broccoli, and seafood. These vitamins can help strengthen your nails and cuticles.
- Drink plenty of water to prevent dehydration, which can lead to brittle nail beds and dry cuticles.
- Avoid painting your nails for 2-3 weeks to give them time to heal and recover. Chronic exposure to nail polish and other chemicals can dry out your nails over time.
- Keep your nails trimmed and avoid nail biting, picking, or tearing, as these habits can cause trauma and damage to your nails.
Medical Treatments:
- For subungual hematomas (blood under the nail), a doctor may perform trephination by making a small hole in the nail to drain the pooled blood. This relieves pain and pressure.
- If the hematoma covers more than a quarter to half of the nail, more aggressive treatment may be necessary. The doctor may remove the nail to repair the nail bed and matrix, and stitches may be required.
- For nail bed lacerations or deep cuts, stitches may be needed. If the injury is severe, the nail may have to be removed, but it should grow back over time.
- For nail bed avulsions, where the nail and nail bed are pulled away from the finger, the nail will likely need to be removed. Finger fractures, which are common with this type of injury, will require splinting for several weeks.
- In some cases, minor surgical procedures on the nail bed can improve the nail's appearance and treat deformities caused by injuries.
It is important to note that anyone uncertain about the severity of their nail bed injury should seek medical advice. While most minor injuries can be treated at home, more severe injuries may require prompt medical attention to ensure proper healing and smooth nail growth.

Nails won't reattach after separation from the bed
A nail that has been torn or detached will not reattach to the nail bed. The main concern after such an injury is damage to the surrounding structures. If there is significant damage to the areas around the nail, a physician should be consulted.
Onycholysis, or nail separation, is the medical term for when a nail separates from the skin underneath it. It is usually caused by trauma to the nail, such as a blow to the nail or finger being closed in a door. However, it can also be caused by fungi, yeast infections, thyroid disease, or a lack of vitamins or minerals, such as iron. Keeping nails short can help to prevent nail trauma, but aggressive clipping is not recommended.
If the nail matrix (the tissue inside the cuticle where new nails are formed) is damaged, a ridge or split may develop. If the matrix heals normally, the deformity will disappear as the nail regrows. Fingernails usually take about two months to regrow, while toenails can take four months or more. However, full recovery from a nail bed injury may take six to nine months, depending on the severity of the injury.
If the nail has been completely lifted off the nail bed, it may be most comfortable to replace the nail and hold it in place with a bandage. As the nail grows out, the affected portion can be clipped off. If the nail is torn or damaged, a doctor may remove it and repair the nail bed. Antifungal medication may be prescribed if the separation is due to a fungal infection.

Prevent infection and dress the wound
The healing time for a nail bed injury depends on the type and severity of the injury. Most nail injuries are noticeable until the damaged nail grows out. Fingernails usually regrow completely in about two months, while toenails can take about four months. However, in some cases, full recovery may take up to 6–9 months.
To prevent infection and dress a nail bed wound, follow these steps:
- Clean the wound: Start by cleaning the wound to remove any foreign material, blood, or debris. Use a mild soap and water to gently clean the area. Ensure that you also wash your hands thoroughly before and after treating the wound.
- Apply a topical antibiotic ointment: After cleaning the wound, apply a thin layer of topical antibiotic ointment to help prevent infection. You can find these ointments at your local pharmacy or ask your healthcare provider for a recommendation.
- Cover the wound: Use a sterile gauze or bandage to cover the wound. This will help keep the area clean and protected. Change the dressing regularly, especially if it becomes wet or soiled.
- Protect the nail: If the nail is still attached, you can try to replace it and hold it in place with a bandage. Nails will not reattach themselves once they have separated from the nail bed, but they can be protected while a new nail grows.
- Manage pain: Nail bed injuries can be quite painful. Take over-the-counter pain medications as needed to help manage any discomfort.
- Monitor for infection: Keep a close eye on the wound for any signs of infection, such as redness, swelling, warmth, or pus. If you notice any of these symptoms, consult a healthcare professional right away.
- Keep the nail trimmed: As the nail regrows, be sure to keep it trimmed and filed smoothly. Avoid biting your nails or cuticles, as this can damage the nail bed and increase the risk of infection.
- Protect your hands: If your job or activities involve exposure to chemicals, detergents, or frequent contact with water, wear protective gloves to prevent irritation and infection.
- Avoid tight shoes: Wear properly sized, well-fitting shoes to reduce further damage to the nails and allow them to heal.
- Seek medical attention: If the injury is severe or if there is significant damage to the surrounding structures, don't hesitate to visit a physician or healthcare provider. They may provide additional treatments, such as stitches or surgical procedures, to ensure proper healing.

Surgical treatment may be required for severe cases
Nail bed injuries are common and can be caused by accidents with a hammer, door, or saw, or by dropping a heavy object on the fingers or toes. Nails can also be accidentally torn or split, or a splinter can get under the nail. Repeated trauma to toenails, caused by ill-fitting shoes, can lead to deformities in the nails. Nail biting and cuticle biting can also cause trauma to the nails.
In most cases, new nails will slowly regrow after being injured or separated from the nail bed. Fingernails usually regrow completely in about two months, while toenails take about four months. However, if the trauma to the nail injures the nail matrix (the tissue inside the cuticle where new nails are formed), a ridge or split can develop, and the deformity will only disappear once the nail regrows.
While many nail bed injuries are minor and can be treated at home, some require prompt medical attention to ensure proper healing and smooth nail growth. Severe cases of nail bed injuries may require surgical treatment to restore function and prevent complications. Surgical treatments may include nailbed repair or nail removal. For example, in cases of severe subungual hematoma (a collection of blood under the nail that looks like a bruise) a doctor may drain the pooling blood by making a small hole in the nail, a procedure known as trephination. If the blood covers more than half of the nail bed, the doctor may remove the nail and repair the nail bed and matrix. Stitches may be used to repair any lacerations to the nail bed, and the nail may be reattached to provide protection and support while the new nail grows.
Minor surgical procedures on the nail bed can also improve the nail's appearance in cases of damage and scarring that produce whitish changes in the nail, known as onycholysis. Additionally, surgical intervention may be necessary to correct abnormal nail growth that occurs following nail bed injuries, resulting in deformed or misshapen nails.
