Toenails are made from keratin, the same protein that makes up our skin and hair. They protect the soft tissue beneath them and keep the tips of our toes safe. Toenails are prone to damage from stubbing, dropping heavy objects, or wearing tight shoes. When damaged, toenails may turn black and fall off. The good news is that toenails do grow back, but it can take anywhere from 6 months to 2 years, depending on the severity of the injury and other factors such as age, climate, and health conditions. Proper toenail care and footwear that allows ample toe space can help prevent issues and promote healthy toenail growth.

What You'll Learn

Toenail regrowth timelines
Initial Healing
After a toenail injury, the initial healing process typically takes around 7 to 10 days. During this time, it is important to protect the exposed nail bed and keep it clean and dry to prevent infection. The area should be coated with a thin layer of petroleum jelly or antibiotic ointment and covered with a non-stick bandage, which should be changed daily or whenever it gets wet.
Nail Regrowth
Once the nail bed has healed, it can take anywhere from several months to a year or more for a new toenail to fully grow back. The rate of growth varies from person to person, but on average, toenails take about 12 months to regrow completely. In some cases, the new nail may have grooves, ridges, or misshapen areas, which could be permanent.
Severe Injuries
For more severe injuries, such as broken bones or extensive bruising, the timeline may be longer. If the bone is broken, it will typically take about four weeks to heal. In cases where the nail bed is damaged or the nail-growing cells are affected, the nail may grow back distorted or may not grow back at all. It is important to seek medical attention for severe injuries to ensure proper treatment and reduce the risk of infection.
Everyday Care
During the regrowth process, it is important to take extra care when wearing shoes and socks to avoid further injury or irritation to the affected toe. Well-fitting sandals or open-toed shoes may be more comfortable during this time. Trimming the nail when needed and filing any rough edges can also help prevent the nail from catching on fabrics and causing further damage.
Promoting Nail Health
To promote nail health and support the regrowth process, it is important to maintain a healthy diet and ensure adequate hydration. Nutrients such as biotin, protein, and omega-3 fatty acids are essential for nail health. Keeping the toenails trimmed and properly maintained can also help prevent future injuries and maintain overall foot health.

Toenail loss causes
Toenail loss is typically caused by trauma or injury to the toe, such as stubbing your toe or dropping something heavy on your foot. This can cause bleeding beneath the nail, known as a subungual haematoma, which can result in the toenail separating from the nail bed and eventually falling off. Other causes of toenail loss include:
- Fungal toenail infections: Fungal infections can cause the toenail to become detached and fall off.
- Allergy to nail product ingredients: An allergy to certain ingredients in nail products can lead to toenail breakage or crumbling.
- Psoriasis: Psoriasis is an autoimmune condition that causes a buildup of skin cells. While it typically affects the skin, it can also impact the toenails, leading to nail detachment and loss.
- Poor circulation: Conditions such as Raynaud's disease, which affect blood circulation, can contribute to toenail loss.
- Tight shoes: Wearing tight-fitting shoes can put pressure on the toes and increase the risk of toenail loss.
- Sports injuries: Injuries sustained during sports activities, such as dropping a heavy object on the foot, can damage the toenail and lead to nail loss.
- Car accidents: Trauma to the toes during a car accident can result in toenail detachment and loss.
It's important to note that toenails can usually grow back within a few months to a year. However, in some cases, it may take up to two years for the nail to fully regrow, and the new nail may appear deformed. Seeking prompt medical attention and following appropriate treatment can help ensure proper nail regrowth.

Toenail loss prevention
Toenail loss is often caused by injury, fungal infection, or psoriasis. To prevent toenail loss, consider the following:
Wear Properly-Fitting Shoes
Avoid shoes that are too tight or short, as they can cause pressure and friction, leading to toenail damage and loss. Make sure your hiking boots fit correctly, and consider getting your feet measured when buying new boots.
Keep Toenails Trimmed
Long toenails can catch on things and increase the risk of detachment. Keep your toenails trimmed straight across to reduce the chances of accidental tearing.
Maintain Foot Hygiene
Keep your feet clean and dry to prevent fungal infections. Fungi thrive in warm, damp environments, so proper foot hygiene is essential to reduce the risk of infection and subsequent toenail loss.
Manage Systemic Health Conditions
Certain health conditions, such as diabetes and peripheral arterial disease, can affect blood circulation and increase the risk of toenail problems. Regular medical check-ups can help manage these conditions and reduce the likelihood of toenail loss.
Protect Your Feet During High-Impact Activities
Wear appropriate footwear during activities that may involve physical trauma to your feet, such as hiking or sports. Proper footwear will help protect your toenails from injury and reduce the risk of toenail loss.
It's important to note that toenail loss is not a natural part of aging, but age-related changes can make nails more brittle and susceptible to damage. By following these prevention tips, you can reduce the chances of toenail loss and maintain healthy toenails.

Toenail loss treatment
Toenail loss is a common condition, often caused by injury, fungal infection, or psoriasis. Chemicals, certain medications, and serious illnesses can also cause toenails to fall off. Toenails can take several months to a year to regrow, and in some cases, they may not grow back at all.
If your toenail has fallen off, you must protect the nail bed from infection. Here are some treatment and prevention tips:
- Use pain medication as needed. Over-the-counter medications such as ibuprofen can help manage pain.
- Apply an antibiotic ointment or cream to the affected area to prevent infection.
- Bandage the toe, especially if the toenail has not completely fallen off. Keep the bandage on for 7 to 10 days until the skin of the nail bed hardens.
- Trim the existing nail to prevent catching or tearing on socks or other items. Use clean scissors or nail clippers to trim along the line of the tear, creating an even edge.
- Soak your toe in cold water for 20 minutes if it is painful.
- Consult a doctor if you experience signs of infection, such as throbbing or intense pain near the affected area.
To prevent toenail loss, consider the following:
- Avoid wearing tight-fitting shoes or shoes that put pressure on the toes.
- Keep your toenails trimmed short and straight across to prevent catching or tearing.
- Always wear cushioned socks with your shoes.

Toenail loss and health conditions
Toenail loss can also be a symptom of various health conditions. For example, people with diabetes often experience reduced sensation in their feet, making them more susceptible to injuries and infections that can lead to toenail loss. Peripheral artery disease and a weak immune system can also increase the risk of toenail problems and loss.
Additionally, certain nail conditions can contribute to toenail loss. Fungal infections, such as onychomycosis, are common and can cause discolouration, thickening, and crumbling of the nail. Ingrown toenails, where the nail grows into the surrounding skin, can also lead to toenail issues and potential loss if left untreated.
Other health conditions that can affect toenails include clubbed nails, leukonychia, and nutritional deficiencies. It is important to consult a healthcare professional if you notice any abnormal changes to your toenails, as proper diagnosis and treatment are crucial for optimal nail health.
In most cases, a broken toenail will grow back, although it may take up to a year for the nail to fully regenerate. During the healing process, it is essential to keep the area clean and dry to prevent infection, especially if the nail bed is exposed. Trimming any loose parts of the nail can also help prevent further tearing and promote healthy regrowth.

Frequently asked questions
Toenails are made of the same protein (keratin) as your skin and hair, and they will usually grow back after being damaged. However, if the nail-growing cells are damaged, the toenail may not grow back.
Toenails can take anywhere from 6 months to 2 years to grow back. The timeline depends on the cause of the damage, the severity of the injury, and other factors such as age and climate. Nails tend to grow faster in the summer and on the dominant hand or foot.
If your toenail is partly detached, don't pull it off. You should also avoid covering the exposed nail bed with plain gauze or a regular adhesive bandage, as these will be painful to remove. Instead, keep the area clean and dry, and cover it with a thin layer of petroleum jelly and a nonstick bandage. Soak your toe in cold water in a solution of warm water and salt a few times a day for the next 3 days.
Wear properly fitting shoes that allow ample space for your toes. This will reduce pressure on the toenails and minimize the risk of them growing into the surrounding skin.
