Toenails are made of keratin, a protein that also makes up your skin and hair, and they play an important protective role. However, due to trauma, infection, or other reasons, you might lose a toenail. Toenails can grow back, usually within 6 months for fingernails and up to 18 months for toenails, but this process can be slower in older adults or in colder climates. To promote healing and prevent infection, it's important to keep the wound clean and dry, applying a bandage and antibiotic ointment. Soaking the foot in saltwater can also help soothe the skin and encourage nail growth. In some cases, surgical removal of the nail may be necessary due to severe fungus, recurrent ingrown toenails, or significant damage. While toenails usually grow back, there is a chance of distortion if the nail-growing cells are damaged or if an infection is present.

Toenails protect the soft tissue underneath and keep the tips of your toes safe
Toenails are made from keratin, a type of tissue comprising amino acid proteins that are also found in hair and other animals' features, such as horse hooves. They protect the soft tissue underneath and keep the tips of your toes safe from injury and infection.
While toenails may seem to have little purpose, they are important for protection. The tops of the toes are vulnerable to injury, and a toenail adds a protective layer to the toe, making it less vulnerable to damage. Toenails also help to resist pressure from the underside of the toe. If you stub your toe, it will hurt a lot more without a toenail!
If you lose a toenail due to trauma, infection, or other reasons, it will grow back, although this can take up to 18 months. In the meantime, the skin underneath will harden and will not be sensitive. To aid the healing process, keep the wound dry and covered. Clean and dry your nail bed daily and cover it with a bandage, changing the bandage once a day. Apply an antibiotic ointment to prevent infection. You can also soak your nail in a saltwater solution to moisturize the area and prevent infection.
There is some evidence that biotin supplements and certain other vitamins can stimulate nail growth, so talk to your doctor about using supplements to support the healing process.

Toenails can take up to 18 months to grow back
Toenails play an important protective role, shielding the soft tissue beneath them and keeping the tips of the toes safe. However, due to trauma, infection, or other factors, you might lose a toenail. The good news is that toenails do grow back, although the rate of regrowth can vary from person to person.
Several factors influence the speed of toenail regrowth. On average, it takes up to 18 months for a toenail to completely regrow. This extended timeframe is partly due to the reduced blood flow to the toes compared to the fingers. Nails also tend to grow slower in older adults and in colder climates. Additionally, overall health can impact growth, with nail growth slowing down if you're sick or malnourished. Hormones also play a role, as nails may grow quicker during pregnancy.
To promote healthy toenail regrowth, it's important to protect the exposed nail bed by keeping it clean and moisturized. Washing your foot regularly with warm soapy water and applying petroleum jelly or vitamin E oil can help prevent infection and scabbing, supporting the healing process. Soaking your foot in a saltwater solution for 15 minutes, 2-3 times daily, can also soothe the skin and encourage nail growth.
If you've had a toenail surgically removed, your doctor will likely provide specific instructions for care. Keeping the wound dry and covered is essential to prevent infection. Elevating the injured toe for the first few days can help reduce swelling and inflammation in the nail bed. Following these steps and maintaining proper toenail care can help ensure your toenail regrows within the expected timeframe of up to 18 months.

Toenail removal may be recommended for a fungal nail infection
Surgical nail removal involves numbing the area around the nail and using special tools to remove either the entire nail or just the infected portion. The procedure typically lasts less than an hour and can be performed in a doctor's office. After the surgery, doctors usually apply antibiotic cream and a bandage to the nail bed to prevent infection.
The nailbed usually takes around 2-3 weeks to heal, and the regrowth process can take up to 18 months for toenails. During this time, it is important to keep the wound clean and dry, changing the bandage daily. Soaking the foot in warm saltwater can help soothe the skin and encourage nail growth. Additionally, biotin supplements and certain vitamins may promote nail growth and aid in the healing process.
While toenails provide protection to the soft tissue underneath, they will typically grow back after removal. To speed up the regrowth process, it is recommended to keep the injured toe elevated for the first few days and follow any specific aftercare instructions provided by your doctor.

Keep the wound dry and covered to prevent infection
It's good to know that toenails can grow back, even though it may take up to 18 months for a new nail to fully regrow. In the meantime, it's important to take care of your toe to avoid infection and promote healing.
After a toenail removal, it is critical to keep the wound dry and covered to prevent infection. The skin underneath the toenail is sensitive, and bandaging keeps the area clean and reduces the risk of infection by preventing dirt and bacteria from entering the wound.
To keep the wound dry and covered, follow these steps:
- Wash your toe with mild soap and warm water or saline to clean it. Ensure that you thoroughly dry your foot afterward with a clean, soft cloth.
- Apply a thin layer of antibiotic ointment to the damaged nail to prevent infection. This will also help to keep the wound moisturized, which is important for healing.
- Cover the wound with a bandage or sterile gauze, ensuring it isn't too tight. Change the dressing about 12 to 24 hours after the surgery and then daily until the wound heals. For the first week, keep the wound covered both day and night. In the second week, you can let your toe remain uncovered at night.
- When showering, use a waterproof bandage or plastic wrap to keep the toe dry. Avoid soaking the toe in water until the wound closes and begins to heal, which can take 1-2 weeks. Soaking too soon can slow healing and increase the risk of infection.
- Wear clean cotton socks and well-fitting, comfortable shoes. Avoid tight shoes, especially for the first 2-3 days, and opt for soft, open-toed shoes or sandals that don't put pressure on the toe.
By keeping the wound dry and covered, you can help prevent infection and promote faster healing.

Toenails may grow back distorted if there is a problem with the toe
Toenails typically grow back within a few months to a year, but this can vary depending on the cause and size of the lost toenail, with some taking up to two years to regrow. Toenails serve an important purpose, protecting the soft tissue underneath and safeguarding the tips of the toes. They are made from keratin, a tough and resilient protein that also constitutes skin and hair.
Toenails may grow back distorted due to various issues with the toe. Fungal infections can cause nails to thicken, distort, and turn yellow, brown, or white. As the infection progresses, nails can become brittle and may grow in an irregular upward direction. Ingrown toenails, which occur when the nail grows into the surrounding skin, can also cause toenails to grow upward. This condition may result in pain, redness, swelling, and infection if left untreated.
Underlying health conditions can also lead to distorted toenail growth. People with diabetes often experience slower nail growth, making them more susceptible to fungal infections that can distort the nail. Poor circulation from peripheral artery disease can cause similar issues, resulting in slow-growing, brittle, distorted, or detached nails. Additionally, physical trauma to the toenail can alter its growth pattern, causing it to turn up on one side. Activities such as running, ballet dancing, or injuries during sports can cause such trauma.
To promote healthy toenail growth and prevent distortion, it is essential to keep the nail bed clean and moisturized. Soaking the nail in a saltwater solution can help moisturize the area and prevent infection. Biotin supplements and certain vitamins may also stimulate nail growth, so consulting a doctor about using supplements can be beneficial. Keeping the toenails trimmed and wearing well-fitting shoes can further reduce the risk of toenail issues and promote proper growth.
