Losing a fingernail or toenail can be a painful and worrying experience. Fortunately, nails have a good regeneration capacity and will grow back over time. However, this can be a slow process, and it's important to take steps to prevent infection and further injury during the healing process. In this article, we will explore the topic of nail regeneration, including the time it takes for nails to grow back, the potential for deformation, and the treatment options available for nail injuries. We will also discuss the causes of nail loss and provide insights into promoting healthy nail growth.

What You'll Learn
Fingernails grow back in 3-6 months
Fingernails can grow back in 3-6 months, but it is important to take the necessary steps to care for the exposed nail bed and prevent infection during this time. The nail bed should be kept dry, clean, and covered with petroleum jelly or neomycin ointment and dressed with a clean bandage until it is firm or the nail has grown back. Any sharp edges should be filed down to prevent catching and tearing.
The rate of fingernail growth is about one-tenth of an inch per month, or about one-tenth of a millimetre each day. Toenails grow more slowly, usually at close to half the rate of fingernails. This means that toenails can take up to 18 months to grow back completely.
It is important to note that if there is damage to the nail matrix or nail bed, the growing nail may be deformed. Minor damage will produce minor defects in the nail, while more significant damage can result in permanent deformation. In the case of severe nail trauma, a physician should be consulted to assess and repair any damage to the nail bed or adjacent tissues.
Nail separation can occur due to various reasons, including injury, fungal nail infection, skin conditions, chemicals, medications, and severe illnesses. To promote nail health and growth, it is recommended to maintain a well-rounded diet and good general health. Additionally, keeping the nails trimmed and avoiding long nails can help prevent nail separation and damage.

Toenails take longer, regrowing in 12-18 months
Toenails take significantly longer to grow back than fingernails. While fingernails typically regrow in 3-6 months, toenails can take anywhere from 12 to 18 months to fully regrow. This extended timeframe is due to the slower growth rate of toenails compared to fingernails. Toenails usually grow at about half the rate of fingernails, sometimes even slower.
The growth rate of toenails can be influenced by various factors. Proper nutrition and overall health play a role in nail growth. A well-rounded diet and good general health contribute to stronger nails. Additionally, age and certain diseases can impact the blood flow to the feet, which may result in slower nail growth.
Toenails are more susceptible to certain issues, such as fungal nail infections. These infections occur when fungi invade the toenail, the skin underneath (the nail bed), or both. Symptoms of a fungal infection include cracked, yellow, discoloured, streaked, thickened, or spotted nails. Such infections can affect the growth of the toenail and may require medical treatment.
Injuries to the toe, particularly those that affect the nail bed and matrix, can also slow down toenail growth. In some cases, the growing toenail may exhibit minor defects or become permanently deformed if the injury was severe. Therefore, it is crucial to keep the nail bed clean, dry, and covered with petroleum jelly or ointment, and to seek medical attention if there are signs of infection, such as increasing heat, redness, pain, or swelling.
The regrowth process for toenails demands patience. During this period, it is essential to maintain proper foot care and hygiene to support the growth of a healthy new toenail.

Nails protect the nail bed
A fingernail that has been torn or detached will take about 4 to 6 months to grow back, while a toenail will take about 12 months. The nail bed will heal in about 7 to 10 days. Nails protect the nail bed, which is the skin at the upper tip of the finger or toe. The nail bed is prone to damage, as it is located at the back of our fingertips and toes. Nails act as a barrier to external trauma, and they also provide a degree of insulation to the sensitive nail bed.
The nail bed is the area of skin that the nail plate rests on. The nail plate is the hard, translucent surface that we commonly refer to as the nail. The nail bed is the soft skin beneath this harder surface. The nail bed is rich in nerve endings and blood vessels, which is why damage to this area can be very painful.
Nails are produced by the nail matrix, which is the moon-shaped, whitish area at the base of the nail. The nail matrix contains cells that produce the nail plate and are responsible for its growth. As long as there is no permanent damage to the nail matrix or nail bed, the nail should regrow normally. Minor damage to the nail matrix will result in minor defects in the regrown nail. More severe damage can lead to permanent deformities.
To protect the nail bed after a nail has been torn or detached, it is important to keep the area dry and clean. Petroleum jelly and ointments can be applied, and the nail bed should be covered with a bandage. Any sharp edges should be filed down to prevent the nail from catching and tearing further. If there is an artificial nail still attached to the nail bed, it should be removed, as it may tear the nail bed further.

Nail injuries can cause bleeding and pain
Fingernails and toenails are composed of protein and fat and are not live tissue. They grow at a rate of about one-tenth of an inch per month. Nails are produced by the nail matrix cells that reside in the moon-shaped whitish area (lunula) at the base of the nail.
For more serious nail injuries, you should go to an urgent care center or the emergency room. They will stop the bleeding and clean the wound. The nail and finger or toe will usually be numbed with medicine before treatment. If there is a large bruise, a doctor will create a small hole in the nail to allow blood and fluid to drain out, relieving pressure and pain.
If the bone is broken or the bruise is very large, the nail may need to be removed, and the nail bed repaired. Part or all of the nail may be removed. Cuts in the nail bed will be closed with stitches, and the nail reattached with a special glue or stitches. If the nail cannot be reattached, a doctor may replace it with a special type of material.

Treatments include home care, medication, and surgery
Fingernails and toenails are composed of protein and fat and are not made of live tissue. Nails grow at a rate of about 0.13 inches per month and require 3-6 months to completely regrow. Toenails grow more slowly, usually taking up to 12 months or 18 months to grow back.
Home Care
If you lose your nail, it will take about 7 to 10 days for the nail bed to heal. Nails grow back slowly, and it may take several weeks for a new nail to appear. To promote healing and prevent infection, keep the area dry and clean. Cover the nail bed with petroleum jelly or neomycin ointment and dress it with a clean bandage. Apply a new bandage whenever the bandage gets wet. File any sharp ends smoothly to prevent them from catching on clothing or socks.
Medication
For more serious nail injuries, visit an urgent care center or the emergency room. The wound will be cleaned, and the bleeding will be stopped. The nail and affected area will be numbed with medicine before treatment. Antibiotics may be prescribed to prevent infection. If there is bleeding between the nail and the nail bed, a doctor may drill a tiny hole in the nail plate to relieve the pressure of the accumulated blood.
Surgery
In the case of subungual melanoma, surgery is required to remove the affected area in the nail matrix and under the nail. If the cancer has spread, chemotherapy or radiation therapy may be necessary. If a nail is partially or completely removed, the nail bed may be repaired with stitches. The nail may be reattached with a special glue or stitches, or replaced with a special type of material.
