Healing Cut Nails: What To Expect

will a cut nail heal

Nail injuries are common and can occur when a heavy object crushes or hits the fingers or toes, or when a sharp object pierces the nail and nail bed. Depending on the severity of the injury, the nail may heal on its own or may require medical attention. Minor nail bed injuries, such as small cuts or scrapes, often heal with home care, while more severe injuries may require a visit to the doctor or hospital. In some cases, the nail may need to be removed and replaced with a special type of material while the nail bed heals. A new nail will then grow in, replacing the old nail. This process can take several months for fingernails and up to 18 months for toenails.

Healing time for cut nails

A cut nail will heal over time, but the healing time depends on the type and severity of the injury. Nails are complex structures involving three layers: the nail plate, the nail bed, and the eponychium (cuticle). Any injury to these layers is considered a nail injury.

Nail injuries can be caused by crushing forces, such as hammers or doors slamming on fingers, or by slicing or cutting with sharp objects. Lacerations or cuts can occur on the nail, the nail bed, or the skin surrounding the nail. In some cases, the nail may be partially or completely avulsed, or lifted off the nail bed, resulting in bleeding and pain.

Minor nail injuries, such as small cuts or scrapes, can often be treated at home with soap and water, followed by bandaging. More serious injuries, such as large cuts or avulsions, may require a visit to the emergency room for treatment. For example, if the bone beneath the nail is broken, the doctor 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 repaired with stitches or glue.

The healing time for a cut nail depends on the severity of the injury. Minor nail bed injuries, such as small subungual hematomas (nail bruises), often heal on their own within a few weeks, with the bruise fading from red or purple-black to blue. More severe injuries, such as those that require medical treatment, may take 6 to 9 months to fully recover, depending on the type and extent of the damage.

During the healing process, it is important to keep the injured area clean and protected. This may involve the use of bandages, splints, or special shoes. Keeping the hand or foot elevated above the level of the heart can help reduce throbbing and pain. Additionally, ice packs can be applied in the initial stages of healing to reduce swelling and discomfort. In some cases, antibiotics may be prescribed to prevent infection.

Home care for nail injuries

Most nail injuries can be treated at home, but some may require medical attention. If you notice any signs of infection, such as pus, redness, or heat around the nail, seek medical help. Additionally, if your nail is black or purple, or if you are experiencing severe pain, it is important to see a doctor or seek emergency care.

If you experience a nail injury, the first step is to treat the wound. If any part of your nail is hanging off, gently trim away the disconnected portion. Then, gently clean the wound with soap and water. Avoid using a dry bandage or gauze on an open wound, as it will stick to the wound once the bleeding stops. Instead, apply petroleum jelly to keep the wound moist, and then cover it with gauze or a bandage. Repeat this process daily as your wound heals. Remember not to put sticky products directly on your nail; only apply them to the skin surrounding your nail.

To reduce swelling, apply a cool, damp washcloth to your wound and prop up your injured arm or leg with pillows so that the nail is positioned higher than your heart. Taking over-the-counter medications like ibuprofen or acetaminophen can also help manage pain and reduce swelling.

To prevent further nail injuries, it is recommended to keep your nails short so they don't bend or catch on objects. Additionally, ensure that your shoes fit well and have a wide toe box to prevent rubbing.

Medical treatment for nail injuries

A nail injury can occur when any part of the nail, nail bed, cuticle, or surrounding skin is damaged. The treatment for a nail injury will depend on the type and severity of the injury. Here is some information on medical treatments for different types of nail injuries:

Nail Bruise (Subungual Hematoma)

For minor nail bruises, home care may be sufficient. This includes keeping the injured hand or foot elevated above the level of the heart to reduce throbbing and pain. Over-the-counter medications like acetaminophen or ibuprofen can be taken for pain, but ibuprofen is preferred if there is also swelling. Any cuts or scrapes should be washed with soap and water, and a bandage can be applied if needed.

For larger nail bruises that occupy more than 25% of the nail, or if there is a bend or deformity in the fingertip, a visit to the hospital's emergency department is recommended. At the hospital, the doctor may drain the blood and fluid to relieve pressure and pain.

Nail Avulsion

Nail avulsion occurs when a portion of the nail is lifted or pulled off the nail bed. This often results in a nail bed injury that requires repair. If the nail bed is not damaged, the nail may be reattached. The doctor may numb the area with medicine before treating the injury. In some cases, the nail may need to be removed and replaced with a special type of material that stays on the nail bed as it heals. Antibiotics may be prescribed to prevent infection.

Broken Bone

If there is a broken bone in the finger or toe along with the nail injury, the treatment will focus on stabilizing the fracture. A wire may be placed in the finger or toe to keep the bone in place, and a splint will be applied. It typically takes about four weeks for the bone to heal.

Fingertip Amputation

In cases of fingertip amputation, the tip of the finger may not be able to be reattached. Advanced techniques may be attempted by specialists, but the success rate is low. The focus of treatment will be on improving the final appearance of the finger and managing any associated nail bed injuries.

It is important to note that for any serious nail injuries, especially those involving cuts, amputations, or potential bone fractures, seeking medical attention at an urgent care center or emergency room is recommended.

Preventing infection

Nail injuries can range from a bruise under the nail to the separation of the nail from the nail bed. These injuries can be complex and may result in permanent deformity.

To prevent infection from a nail cut, it is important to keep the wound clean and to take care of your hands and nails. Wash any cuts or scrapes with soap and water, and apply a bandage if needed. Keep the injured area elevated above the level of the heart to help with throbbing and swelling. You can also apply ice to the wound, through a cloth, for 20 minutes every 2 hours on the first day, then 3 to 4 times a day after that.

If the nail is separated from the nail bed, it is important to seek medical attention. A doctor may prescribe antibiotics to prevent infection and will likely reattach the nail or provide a replacement. If you have broken the bone under your nail, your provider may need to place a wire in your finger to keep the bone in place.

Paronychia, a bacterial or fungal skin infection, can occur when bacteria enter broken skin near the cuticle and nail fold. Symptoms include inflammation, swelling, pain, and discomfort. To prevent paronychia, it is important to not bite or pick at your nails, cut your nails regularly, and avoid pushing back, trimming, or removing your cuticles.

Regrowing cut nails

A fingernail cut is a common injury, and fortunately, the nail will usually heal and regrow. Nails grow more than one-tenth of an inch per month and require 3-6 months to fully regrow. Toenails grow more slowly, usually taking about 12 months to grow back.

If you have cut your nail, the first step is to assess the severity of the injury. If it is a minor cut, you can treat it at home by cleaning the wound with soap and warm water, applying an antibiotic ointment, and bandaging the area. It is important to keep the wound clean and to change the bandage daily. You can take over-the-counter pain medication such as acetaminophen or ibuprofen to manage any pain or swelling. Keep the injured area elevated above the level of your heart to help reduce throbbing and discomfort.

If there is significant damage to the nail or surrounding structures, such as a deep cut or injury to the nail bed, it is important to seek medical attention. Your healthcare provider will examine the injury and determine the appropriate treatment. They may need to remove the nail to repair any underlying tissue damage. In some cases, they may reattach the nail or use a special type of material to protect the nail bed as it heals. Antibiotics may be prescribed to prevent infection.

To promote nail regrowth, it is important to maintain a well-rounded diet and good general health. Nails are produced by nail matrix cells, and any damage to these cells can affect nail regrowth. Protecting the nail bed during the healing process is crucial to ensure the nail can regrow properly. Keeping your nails trimmed and avoiding poorly fitting shoes can help prevent nail injuries and promote healthy nail growth.
