Nails have a good regeneration capacity, but they grow slowly. Fingernails may grow one-tenth of a millimeter each day, so completely removed fingernails usually grow within 6 months. Toenails may grow at about half or one-third the rate of fingernails, so they may take up to 18 months to grow back. However, if the root of the nail is damaged, the nail may never grow back or may grow back with deformities. In some cases, a doctor may perform a procedure to kill the root and prevent the nail from growing back as a solution for chronic ingrown nail issues.

What You'll Learn
Nails do grow back, but slowly
While nails do grow back, it is a slow process. Fingernails may grow at a rate of about one-tenth of a millimeter each day, with a complete regeneration taking up to 6 months. Toenails, on the other hand, grow at a slower pace, typically achieving full regrowth in about 18 months. The rate of nail growth can be influenced by various factors, such as age and certain diseases, which may decrease blood flow to the hands and feet.
In the case of nail injuries or issues, such as ingrown toenails or fingernails, it is possible to surgically remove the nail partially or completely. This procedure, known as onychectomy, can provide relief from pain and discomfort caused by abnormal nail growth. However, it is important to note that nail removal may result in permanent changes to the nail's appearance. For example, if the root of the nail is damaged during an injury or surgery, it can leave a noticeable groove or straight line in the nail as it regrows.
To promote healthy nail regrowth after a removal or injury, it is essential to keep the area clean and dry to prevent infection. Home treatments, such as trimming sharp edges and covering the nail with tape or a bandage, can help manage pain and protect the nail bed until a new nail grows in. Additionally, soaking the affected area in a warm salt solution and applying petroleum jelly can aid in the healing process and maintain nail bed health.
While nail regrowth typically occurs, there may be instances where the nail grows back thickened or deformed. In such cases, further treatment options can be discussed with a doctor. For example, in the case of toenail fungus, topical medications can be applied to the exposed nail bed during the regrowth process to improve the efficacy of the treatment.

Fingernails grow faster than toenails
Nails do grow back, but the rate of growth varies between fingernails and toenails. Fingernails grow faster than toenails, with a daily growth rate of about one-tenth of a millimeter, resulting in a complete regeneration in approximately 6 months. Toenails, on the other hand, grow at a slower pace, taking about half to a third of the time it takes for fingernails to grow, which means they usually take around 18 months to fully regrow.
Several factors can influence the growth rate of nails. Aging and certain diseases can decrease blood flow to the hands and feet, causing slower nail growth. Additionally, nail injuries can impact the growth pattern and overall appearance of the nail. In some cases, injuries may cause permanent damage to the nail root or nail bed, resulting in deformed nail growth or a complete absence of regrowth.
It is important to note that ingrown toenails, a common issue, occur when the side corners of the toenail grow into the surrounding nail fold and pierce the soft tissue. This condition can cause pain and discomfort, sometimes requiring partial or complete toenail removal. Similarly, fungal infections, such as tinea, can affect both fingernails and toenails, leading to discolouration, thickening, and brittleness. In severe cases of fungal infections, toenail removal may be recommended to expose the nail bed for more effective topical treatments.
To promote healthy nail growth and prevent complications, it is crucial to take proper care of your nails and address any underlying conditions or injuries. This may include wearing appropriate footwear, maintaining nail hygiene, and seeking medical advice for persistent or severe nail issues.
While nails typically grow back, the rate of growth differs between fingernails and toenails, with fingernails regenerating faster and taking less time to fully regrow compared to toenails.

Toenail removal is recommended for thickened, painful toenails
Fungal infections, such as onychomycosis, can cause discolouration (yellow, green, or brown) and a foul odour. In some cases, the nail may separate from the nail bed (onycholysis), leading to a white or yellow appearance. Left untreated, these infections can worsen and cause further complications, including foot ulcers. Therefore, prompt treatment is essential to prevent the condition from worsening and to relieve symptoms.
Treatment options for thickened, painful toenails include topical treatments, oral medications, and surgical removal. Surgical removal, or onychectomy, involves the partial or complete removal of the toenail. This procedure is recommended when the thickened toenail causes significant pain and discomfort, especially if it is affecting the ability to walk or wear shoes comfortably.
After toenail removal, it is important to follow the doctor's instructions for care. This may include wearing appropriately fitted footwear, completing the prescribed course of medication, and keeping the wound clean and dry. It is also crucial to watch for signs of infection, such as increasing heat, redness, pain, tenderness, swelling, or pus.
The regrowth process for toenails can take up to 18 months, so patience is required during this slow regeneration process. During this time, home treatments can help relieve pain, promote healing, and prevent infection. Keeping the area dry and covering any sharp edges or detached parts of the nail with tape or a bandage can aid in protecting the toe until the new nail grows back.

Injured nails can become infected
Injured nails are susceptible to infections, which can have serious consequences if left untreated. Nails grow back slowly, taking about 6 months for fingernails and up to 18 months for toenails to fully regenerate. During this extended period, it is crucial to prevent infections and manage any injuries properly.
Nail injuries can create an entryway for bacteria and germs to invade, leading to infections such as paronychia. Paronychia is a common nail infection that occurs when bacteria enter broken skin near the cuticle and nail fold. It is typically caused by bacteria like Staphylococcus aureus and Streptococcus pyogenes, which gain entry through cuts, broken skin, hangnails, or trauma to the nail bed. Ingrown toenails, water or chemical irritation, and frequent manicures or pedicures can also lead to paronychia.
The risk of infection is heightened in individuals with diabetes or conditions affecting blood circulation. Bacterial paronychia often manifests abruptly, with noticeable symptoms such as red, swollen, warm, and tender skin around the nail. On the other hand, fungal paronychia may go unnoticed for longer and cause chronic infections, resulting in discolored, opaque, or abnormally shaped nails.
To prevent and manage nail infections, it is essential to practice good nail hygiene. This includes avoiding nail biting or picking, maintaining clean hands and nails, and refraining from cutting nails too short. In the event of a nail injury, it is crucial to keep the area clean and dry, trim any sharp edges, and cover the nail with tape or a bandage until it heals. For more severe infections, antibiotics or antifungal medications may be prescribed to eradicate the infection.
In rare cases, untreated nail infections can progress and lead to serious complications. Paronychia, if left untreated, can spread deeper into the finger or toe and even involve the underlying bone. In severe instances, the affected digit may need to be removed to prevent the infection from spreading throughout the body. Therefore, it is imperative to seek medical attention if an injury occurs and to properly care for nails to minimize the risk of infection.

Damaged root beds can cause permanent nail deformities
While nails do grow back, it can take a long time. Fingernails, for example, grow at about one-tenth of a millimeter per day, meaning it could take up to 6 months for a completely removed fingernail to grow back. Toenails grow even more slowly, at about one-half or one-third the rate of fingernails, meaning a removed toenail could take up to 18 months to grow back.
However, this process is dependent on a healthy nail root or nail bed. The nail root is generally quite resilient, but it is still susceptible to damage. Accidents or injuries can damage the root, and if this happens, the nail may never grow back. This damage can manifest as a permanent split nail or other deformities, such as a deep groove in the nail.
In some cases, a doctor may intentionally kill the root as a more permanent solution to chronic issues with ingrown nails. This procedure involves applying a chemical agent to burn the skin on the root, causing it to scar and preventing future nail growth.
Leaving an artificial nail on after a nail removal procedure can also lead to tearing of the nail bed, which may result in further complications and deformities. Therefore, it is important to follow the proper aftercare instructions provided by a medical professional to ensure the nail bed remains intact and to promote healthy nail regrowth.
