Fingernails and toenails can be injured by a blow to the nail, by closing a finger or toe in a door, or by cutting with a sharp object. Toenails grow more slowly than fingernails, with the latter growing at a rate of 0.13 inches per month and requiring 3-6 months to completely regrow. Toenails, on the other hand, can take about 4-12 months to grow back. The new nail will likely have grooves or ridges and may be misshapen, which could be permanent.

Fingernails take 2-6 months to grow back, while toenails take 4-12 months
Fingernails and toenails can be injured by a blow to the nail, by closing a finger or toe in a door or drawer, or by nail biting and cuticle biting. Toenails are more prone to damage caused by ill-fitting shoes, which can lead to deformities. Nails grow from the root, and trimming them encourages growth.
If the nail is torn or detached, it is unlikely to reattach to the nail bed, but it will usually regrow. The nail matrix is the part of the body that produces nails, and if it is damaged, the growing nail may contain defects. Minor damage will produce minor defects, while more significant damage can result in a permanently deformed nail. The nail bed is the area of skin at the upper tip of the finger or toe, and it is protected by the nail.
If the nail bed is injured, it will take around 7 to 10 days to heal. A new fingernail will take about 4 to 6 months to grow back, while a toenail will take about 12 months. Fingernails grow at a rate of 0.13 inches per month, while toenails grow more slowly.
To prevent infection, the damaged skin should be covered with a dressing, and any unattached remnants of the nail should be removed with a nail clipper. The nail bed should be cleaned with soap and water, and any sharp ends should be filed down. The nail bed can then be covered with petroleum jelly or neomycin ointment and dressed with a clean bandage.

Nails grow at a rate of 0.1-0.13 inches per month
The rate at which a broken nail grows back depends on various factors, including the severity of the injury, the health of the individual, and the treatment provided. On average, fingernails grow at a rate of about 0.1 to 0.13 inches per month, translating to approximately 2-3 millimetres. This growth rate implies that it would take about three to six months for a fingernail to regrow entirely.
The growth rate of nails can vary among individuals, with some experiencing faster nail growth than others. Genetics, age, and overall health are factors that influence nail growth rate. Additionally, maintaining a well-rounded diet and good general health can contribute to stronger nails that are less prone to damage.
The matrix, the whitish moon-shaped area at the base of the nail, is responsible for nail production. When a nail is damaged or torn, it is essential to assess whether the nail matrix has been affected. Minor damage to the matrix may result in minor defects in the nail, while more significant damage can lead to permanent deformities.
In most cases, nails are capable of regrowing if the nail matrix is not severely damaged. Proper nail care and maintenance can aid in the regrowth process and prevent further issues. This includes keeping nails trimmed and avoiding habits such as nail-biting or cuticle biting, as these can also cause trauma to the nails.
It is worth noting that toenails tend to grow back more slowly than fingernails, typically taking about four to twelve months to regrow completely. This extended timeframe is due to the slower growth rate of toenails compared to fingernails.

Nail matrix damage can cause permanent nail deformities
A broken nail typically takes around four to six months to grow back completely, but this timeline can vary depending on various factors. Toenails, for instance, tend to take longer to regenerate than fingernails, with regrowth periods ranging from 12 to 16 months.
Now, let's delve into the topic of nail matrix damage and its potential consequences:
Nail Matrix and Its Role in Nail Growth
The nail matrix is the region beneath the base of the nail where new nail cells are produced, facilitating nail growth. It consists of two parts: the germinal matrix and the sterile matrix. The germinal matrix contributes to about 90% of nail growth, giving the nail its natural curvature. The remaining 10% of nail cells are formed in the sterile matrix, which also plays a crucial role in keeping the nail attached to the underlying skin.
Impact of Nail Matrix Damage
Injuries or conditions affecting the nail matrix can have both temporary and permanent effects on nail growth and appearance. Minor matrix damage may result in temporary changes such as dents, horizontal ridges, soreness, splits, discolouration, and texture alterations (e.g., thicker or crumbly nails). These changes usually resolve as the nail grows, allowing new, healthy cells to replace the damaged area.
However, severe trauma, such as deep cuts or crushing injuries, can lead to long-term or permanent nail deformities if the nail matrix sustains significant damage. In such cases, conditions like chronic thickening, uneven or irregular nail growth, and, in rare instances, complete and permanent nail loss may occur. The severity of these changes often depends on factors like the depth and location of the trauma. For example, damage near the cuticle is more likely to cause significant and lasting changes than an injury at the tip of the nail.
Treatment and Prevention
While nail matrix damage can lead to permanent nail deformities, proper medical care can often promote healthy nail regrowth. Consulting with skilled practitioners, such as dermatologists or physicians, is crucial to determine the best treatment approach. They may recommend trimming damaged sections, draining blood under the nail, or, in severe cases, surgical procedures.
To minimise the risk of nail trauma and potential matrix damage, it's advisable to wear protective gloves during tasks that may expose your nails to injury. Keeping nails trimmed and well-maintained can also reduce the likelihood of breakage. Additionally, wearing properly sized and well-fitting shoes is essential to prevent toenail trauma and potential nail deformities.

Treatments for nail injuries include antibiotics, surgery, and pain relievers
A broken nail will take around 4 to 6 months to grow back, with toenails taking up to 12 months. Nails grow at a rate of 0.1 to 0.13 inches per month. If the nail matrix is not damaged, the nail should regrow normally.
Nail injuries can range from minor to severe, and treatments will vary depending on the extent of the injury. Here are some treatments for nail injuries, including the use of antibiotics, surgery, and pain relievers:
Antibiotics
Nail injuries can sometimes lead to bacterial infections, such as paronychia, which require antibiotics to treat. Paronychia develops when bacteria enter broken skin near the cuticle or nail fold. Signs of infection include pain, swelling, redness, warmth, and the presence of pus. Antibiotics help kill the bacteria causing the infection and are often prescribed to prevent infection after surgery as well.
Surgery
In more severe cases of nail injuries, surgery may be required. This could involve repairing lacerations to the nail bed and nail matrix, or addressing fractures and tendon injuries in the digit. Surgery can also be performed to improve the appearance of the nail if there is damage to the nail bed. Before surgery, the injured digit is thoroughly cleaned, and antibiotics are administered to prevent infection.
Pain Relievers
Nail injuries can be quite painful, and prescription or over-the-counter pain relievers can help manage this pain. Options include prescription pain relievers, ibuprofen, naproxen, and acetaminophen. It is important to follow the provider's recommendations and instructions when taking these medications.

Prevent nail injuries by wearing properly sized shoes and keeping nails short
A broken nail can take anywhere from a few months to an entire year to grow back, depending on the severity of the injury and whether it was a fingernail or toenail. Toenails, in particular, can take up to a year to fully regrow, while fingernails typically take around 4 to 6 months. Nails grow at a rate of about one-tenth of an inch per month, so it will take some patience for the nail to fully heal.
In the meantime, there are several measures you can take to prevent nail injuries and promote healthy nail growth. One of the most important is to wear properly sized shoes. Ill-fitting shoes are a common cause of toenail trauma and can lead to deformities in the nails. Repeated trauma to the toenails from shoes that are too tight or too loose can cause permanent damage, such as thickening, discoloration, and lifting of the nails. Therefore, it is crucial to invest in comfortable shoes that fit well and provide ample room for your toes and nails.
In addition to wearing proper footwear, keeping your nails short can also help prevent injuries. Longer nails are more prone to damage as they can easily catch on surfaces or run into the end of your shoes. Trimming your nails regularly helps to reduce the risk of nail trauma and also improves the appearance of your nails. However, it is important to cut your nails properly to avoid ingrown nails, especially when trimming your toenails. Cut them straight across and avoid cutting the sides down too far, as this can lead to pain and inflammation.
Maintaining short and well-groomed nails is a simple yet effective way to prevent injuries and maintain nail health. It is also beneficial to be mindful of your surroundings and avoid dangerous situations that could potentially harm your nails or toes while they are healing. Taking these preventative measures can help you avoid the pain and inconvenience of a broken nail and ensure your nails stay strong and healthy.
If you do experience a nail injury, it is important to take the necessary steps to care for it properly. Minor nail injuries can often be managed at home by cleaning the wound, trimming any jagged edges, and covering the area with a bandage. However, if there is significant trauma or any signs of infection, it is crucial to seek medical attention promptly to prevent further complications and ensure proper healing.
