Fingernails and toenails falling off due to trauma or infection is a common occurrence. Trauma to the nail can be caused by dropping something heavy on it, stubbing your toe, or wearing ill-fitting shoes. Infections can be caused by fungi, skin conditions such as psoriasis, or harsh chemicals. Nails are made of dead cells and will not reattach once they have fallen off. However, you don't need to worry because your body will grow a new nail, although it may take some time and patience. The time it takes for a nail to grow back depends on the person and their health, with some nails taking up to 18 months to fully regrow.

Nails are made of dead cells and will not reattach after falling off
Our nails are made of a protein called keratin, which is produced by nail-growing cells in the nail root, found deep beyond our cuticles. This process involves the new nail pushing out the older nail at the tips, resulting in longer nails. However, it is important to understand that the visible part of our nails is made of dead cells.
When nails fall off due to injury or other reasons, they will not reattach to the nail bed. This is because dead cells do not have the capacity to reattach or regenerate. Instead, a new nail will grow back to replace the lost nail. The nail regeneration process can take time, typically ranging from 4 to 6 months or even up to 18 months in some cases. During this time, it is essential to keep the nail bed clean, dry, and protected to prevent infections and ensure proper regrowth.
Various factors can cause nails to fall off, including trauma, fungal infections, and skin conditions. Trauma to the nails can result from dropping heavy objects on them, stubbing toes, wearing tight shoes, or not trimming long toenails. Fungal infections occur when fungi invade the space between the nail and the nail bed, and they can be challenging to treat. Skin conditions such as psoriasis can also contribute to nail detachment.
To promote nail health and prevent issues, it is recommended to keep nails trimmed and well-maintained. Additionally, maintaining good overall health is crucial for supporting the nail regeneration process, as certain conditions like diabetes and peripheral arterial disease can slow nail growth by affecting blood flow to the extremities.
While it may be distressing to lose a nail, it is reassuring to know that, in most cases, nails will grow back. However, it is always advisable to seek professional medical advice if you have concerns or if an injury is causing pain or discomfort.

A new nail will grow back in place, but it takes time and patience
Losing a nail can be a distressing experience, but it is comforting to know that a new nail will grow back in place. This process, however, requires time and patience.
When a nail falls off, it is usually due to trauma or injury. This could be from dropping something heavy on the nail, stubbing a toe, or even having a dog jump on your toe. In some cases, tight shoes or long toenails that constantly press against the end of the shoe can also lead to nail loss. Regardless of the cause, the result is often damage to the nail and underlying nail bed.
It is important to understand that once a nail separates from the nail bed, it will not reattach. The original nail is composed of dead cells, and it is biologically impossible for it to reattach. However, this doesn't mean you are left without a nail forever. Your body is designed to regenerate nails, and a new nail will begin to grow in place of the old one.
The time it takes for a new nail to grow back can vary. Typically, it takes around 4 to 6 months for a fingernail to regrow completely. Toenails may take even longer, with some people reporting a regrowth period of up to 18 months. During this time, it is crucial to keep the nail bed clean and dry to prevent infections. Covering the area with petroleum jelly and an adhesive bandage can aid in this process and protect the sensitive nail bed.
While waiting for your nail to grow back, it's important to be mindful of any signs of infection. Keep an eye out for increasing heat, redness, pain, tenderness, swelling, or pus. If you notice any of these symptoms, it is important to seek medical advice promptly. Additionally, certain underlying health conditions, such as diabetes or peripheral arterial disease, can impact the speed of nail regeneration, so it's important to be aware of any potential factors that may influence the process.

Keep the nail bed clean and dry to prevent infection
Nails are made of a protein called keratin and are constantly being renewed by the body. As long as there is no interference with the nail-growing cells, your nails will continue to grow back. However, if the nail bed is damaged, the nails may not grow back. To prevent infection and promote nail growth, it is important to keep the nail bed clean and dry.
Clean the nail bed
- Wash your hands regularly with antibacterial soap or use an alcohol-based hand sanitizer to reduce bacteria on the fingertips and nails.
- Pay attention to your nails when you wash your hands. Use lukewarm water and an orange stick (cuticle stick) to manually remove dirt from under your nails.
- If your hands are visibly soiled, use a nail brush to clean under your nails. Remember to wash and air-dry the nail brush afterward to prevent the accumulation of bacteria.
- Keep your nails short and evenly trimmed to prevent the collection of bacteria and dirt.
Keep the nail bed dry
- After washing your hands or nails, dry them thoroughly. This minimizes the likelihood of a nail infection.
- Apply a moisturizer to your nails and cuticles to seal in moisture and keep your nails flexible and healthy. You can use products that contain lanolin or oils such as almond, vitamin E, or coconut oil.
- If you have injured your toenail and there is bleeding beneath the nail, trim the nail carefully to prevent dirt and bacteria from getting trapped.
Remember to watch for signs of infection such as increasing heat, redness, pain, tenderness, swelling, or pus. If you notice any of these symptoms, seek medical advice.

Diabetes and peripheral arterial disease can slow nail regeneration
In most cases, nails will grow back over a few months if they fall off. However, this process can be slower for people with certain conditions, such as diabetes and peripheral arterial disease.
Peripheral arterial disease (PAD) refers to the partial or complete blockage of the peripheral vessels in the upper and lower limbs. It is often associated with atherosclerosis in the coronary and cerebral arteries. PAD is a common complication of diabetes mellitus (DM), with diabetic patients having more than twice the prevalence of PAD compared to the general population. The link between PAD and diabetes can lead to serious issues such as diabetic foot ulcers (DFUs), which can cause hyperglycaemic emergencies, hospitalisations, reduced quality of life, and even mortality.
Furthermore, nail abnormalities can be an early indicator of peripheral arterial disease. Onychodystrophy, a deformity of the nail plate, can be a sign of PAD, especially in elderly individuals. Nail evaluations are simple and non-invasive, making them an accessible tool for the early detection of PAD. By identifying PAD early, individuals can receive timely treatment and potentially prevent the development of more severe complications.
In summary, while nails typically grow back after falling off, individuals with diabetes and peripheral arterial disease may experience slower nail regeneration due to reduced blood flow and associated complications. Nail abnormalities can also serve as a marker for PAD, emphasising the importance of regular nail evaluations, particularly for those at risk.

Stubbing your toe or wearing tight shoes can cause toenails to fall off but they will usually grow back
Stubbing your toe or wearing ill-fitting shoes can cause toenails to fall off. This is because the nail exceeds the nail bed, causing it to separate and appear white instead of its usual pink colour. If the nail bed is damaged, the nail may not grow back. However, in most cases, toenails will grow back, although it may take up to 18 months.
Toenails fall off due to trauma, such as stubbing your toe, or wearing tight shoes or sports boots. This can cause bleeding beneath the nail, which puts pressure on the nail, and the nail may fall off after several weeks. If the nail is only partly detached, it is important to leave the remaining part of the nail in place and trim or file any jagged edges to prevent further injury.
If the nail has completely fallen off, it is important to keep the nail bed clean and dry, and covered with petroleum jelly and a bandage until the nail has grown back. This will help to prevent infection. Signs of infection include increasing heat, redness, pain, tenderness, swelling, or pus.
It is also important to wear well-fitting shoes and socks and keep the nails well-trimmed to prevent further injury. Toenails are more susceptible to falling off because the warm, dark, and moist environment inside shoes makes them more vulnerable to fungal infections.
Fungal infections can cause the nail to separate and fall off. Treatment for fungal infections can be difficult and may require topical creams, oral antifungal medications, or a combination of both. In some cases, surgery may be necessary to remove the nail and stop it from growing back. However, with proper treatment, a new, healthy nail should grow back within 4-6 months.
