Toenail Falling Off? What to Do, the Stages, and Whether It Grows Back
Why nails come loose, whether to trim, tape or leave one that is hanging on, how to look after the bare nail bed, and the signs that mean it needs a clinician.
A toenail falling off looks alarming, but it is usually the end of something that started weeks earlier: a stubbed or crushed toe, months of shoes pressing on the nail, a fungal infection, psoriasis, an illness or a medicine. The nail itself can be replaced. What matters now is not tearing off the part that is still attached, keeping the bare nail bed clean, and spotting the few situations that need a clinician.
Below: why toenails come off, the stages from lifting to loose to gone, what to do with a nail that is hanging on, and how to look after the toe. If your nail was taken off in a procedure, the toenail removal recovery timeline covers that aftercare instead.

The short answer
If your toenail is falling off, do not rip it off. Trim the loose part back to where it is still attached, or tape it flat so it cannot catch, and keep the toe clean and covered until the nail bed underneath has dried and scabbed over. Most toenails come off after an injury or repeated shoe pressure, a fungal infection, psoriasis, or an illness or medicine, and a new nail usually grows back, taking about 12 to 18 months for a big toenail. Get it seen if the toe is red, hot, swollen or oozing, if pain under a freshly injured nail is severe, or if you have diabetes.
Get It Seen Promptly If
See a podiatrist or doctor, the same day for the first three:
- •Severe, throbbing pain under a nail injured in the last day or two. Releasing the blood works best within 24 to 48 hours, and only a clinician should do it
- •The nail was torn off with a deep cut, bleeding that will not stop, or a toe that may be broken
- •The toe is red, hot or swollen, with pus, thick milky fluid or a strong smell, or you have a fever
- •You have diabetes, neuropathy, poor circulation, or a weakened immune system, including during chemotherapy
- •A dark band or dark color you cannot link to an injury, especially if the skin around the nail darkens too
- •Several nails are loosening at once, or a nail came off and you do not know why
Why Is My Toenail Falling Off?
A toenail comes off in one of two ways. Most often it lifts away from the nail bed, starting at the tip or a side edge, which dermatologists call onycholysis. Less often the nail sheds from the base, by the cuticle, because the tissue that makes the nail paused for a while; that is onychomadesis. Either way, the separated part never sticks back down.
| Cause | What you usually notice | What happens to the nail |
|---|---|---|
| A stubbed, crushed or dropped-on toe | Pain at the time, then a red, purple or black nail as blood collects underneath. The color can take several weeks to show. | Blood lifts the nail off its bed. It often loosens and eventually comes off. |
| Repeated pressure (runner's toe) | A sore, darkening nail after walking or running more than usual, or after weeks in shoes that are too small or tight. | The same bleeding and lifting as an injury, built up over many small knocks against the shoe. |
| Fungal nail infection | Starts at the edge. The nail turns white or yellow, thickens and crumbles. Athlete's foot can spread to it. | Lifts from the edge, and sometimes the whole nail lifts off. It is cured only when healthy nail grows back from the base. |
| Psoriasis | Lifted white or yellowish areas, sometimes with yellow-pink patches or pits in the surface, often with psoriasis elsewhere. | Separates from the nail bed. Keeping it short and protected helps the new growth stay attached. |
| Medicines, including chemotherapy | Changes in several nails weeks or months after starting a drug, such as taxane chemotherapy, retinoids, some antibiotics or anti-inflammatory painkillers. | Lifting, or shedding from the base. Most improve once the drug is stopped, though some changes last. |
| After an illness (onychomadesis) | Several nails loosening at the base weeks after a fever or a virus such as hand, foot and mouth disease. | Sheds from the base after nail growth briefly stops, and usually regrows normally. |
| Thyroid and other conditions | Several nails lifting with no local cause, sometimes with tiredness, weakness or a fast heartbeat. | Lifting that needs the underlying condition found and treated. |
One toenail
Points to something local: an injury, pressure from footwear, or fungus in that nail. A toenail falling off with no injury you remember is often shoe pressure you did not notice, or fungus.
Several nails at once
Points to something affecting the whole body: a recent illness, a medicine, psoriasis, or a thyroid problem. The NHS advises seeing a doctor when a nail has fallen off and you do not know why.
Nail color is a clue too. What yellow, white, green and brown nails usually mean is in toenail discoloration.
Toenail Falling Off Stages: From Lifting to Loose to Gone
There is no fixed schedule. A nail can hang on for weeks or months, and one that has only partly lifted may simply be trimmed back as it grows out rather than coming off at all. Most go through the same steps, though:
The Trigger
- An injury, repeated shoe pressure, fungus, psoriasis, an illness or a new medicine
- After a knock, pain usually eases over a few days, but the dark color can take several weeks to appear
- After an illness or a new drug, nothing may show for weeks: nail shedding after hand, foot and mouth disease is usually noticed 4 to 8 weeks later
Lifting Starts
- The separated part looks white, yellowish or dark, with a sharp border against the pink nail that is still attached
- When the trouble starts at the base, a groove or line runs across the nail near the cuticle instead
- The lifted part will not stick back down. Only new nail can grow in attached
Loose
- The nail moves when touched and catches on socks or bedding
- Tape it flat, or trim the loose part back to where it is still attached
- The skin underneath may be damp. If it stays damp, see the aftercare steps below
Off
- The bare nail bed is tender at first and may be moist
- Keep it clean and covered until it is dry and scabbed over, then protect it in roomy shoes
The New Nail
- New nail grows forward from the base of the toe
- A toenail takes about 12 to 18 months to grow all the way out, so the big toe takes the longest
Toenail Turning Black and Falling Off
This is the classic pattern. A heavy object lands on the toe, you stub it hard, or the toe keeps hitting the front of a shoe that is too small or tight, often after walking or running more than usual. Blood collects under the nail, which is called a subungual hematoma, and turns it red, purple or black. The pressure of that blood lifts the nail off its bed, so it often loosens and eventually comes off, with a new nail growing in its place.
Usually fine to manage at home
- Pain that is easing after a few days
- No cut, no bleeding from the nail edge, and a toe that looks straight
- Ice wrapped in a soft cloth for the swelling, and roomy shoes
Needs a clinician
- Intense or throbbing pain, or pain getting worse over the next few hours
- A deep cut, bleeding that will not stop, or a toe that may be broken
- Diabetes, neuropathy or poor circulation
For a painful, freshly injured nail, a clinician can make a tiny hole in the nail to let the blood out, called trephination. It works best within 24 to 48 hours of the injury, and the pain often eases right away. Never do it yourself with a heated paper clip or a needle: home attempts risk infection and further damage.
When a black nail is not blood
The American Academy of Dermatology lists these nail changes as reasons to see a dermatologist: a new brown or black band in the nail, the skin around the nail getting darker, a nail separating from the nail bed or splitting down the middle, and a bump under the nail. If there was no injury, or the dark area is not growing out with the nail, have it examined rather than waiting for it to fall off.
The full list of black nail causes is in why toenails turn black, and a single dot or streak is covered in black spot under toenail. If the whole toe hurts, not just the nail, see bruised toe healing time to tell a bruise from a break.
Should You Pull Off a Loose Toenail?
No. NHS advice is to cut injured, loose nails back to where they are still attached, not to pull them. A nail that is still stuck down at the base or sides is still attached to the nail bed, and ripping it free tears that tissue, leaves a raw wound, and invites infection. Damage to the nail bed is also what makes a new nail grow in ridged or misshapen. What to do depends on how much is still holding on:
Hanging on by a strip
Trim it with clean clippers at the line where it is still attached, then smooth the edge with a file. Do not pull the last bit free.
Lifting at the tip or one side
Trim the lifted part back and keep the nail short. The detached part will not reattach, so trim more away as the nail grows out.
Loose but still fixed at the base
Tape it flat so it cannot catch. No other treatment is usually needed; it can come away in its own time or be trimmed by a podiatrist.
Painful, red or swollen around it
Leave it and get it seen. Trimming an inflamed toe at home, or with diabetes or poor circulation, can turn a nail problem into a wound problem.
How to trim a loose toenail safely
- 1Wash your hands and the foot, and use clean, sharp clippers. Good light helps.
- 2Find the line of attachment. The attached nail looks pink; the loose part is white, yellow or dark and moves when pressed gently.
- 3Snip the loose part straight across, a little short of that line, in small cuts rather than one big one. Stay off the skin.
- 4File any sharp edge smooth so the corner cannot catch on socks or dig into the next toe.
- 5Stop if it bleeds or hurts sharply. That means you are into attached nail. Cover it and leave the rest for a podiatrist.
Taping a loose toenail down
An NHS podiatry leaflet's advice for a loose toenail is simply to tape it down so it cannot catch on socks; no other treatment is usually needed, and if it comes off entirely in time, a new nail is highly likely to grow through.
- •Dry the toe, then lay a strip of medical or cloth tape over the nail and onto the skin of the toe.
- •Snug, not tight: the tip of the toe should stay its normal color and warmth.
- •Replace it daily and whenever it gets wet, and check the skin each time.
Thick, fungal or hard-to-reach nails are a job for a podiatrist; the NHS suggests one when your nails are too tough to cut or you cannot reach them.
How to Care for Your Toe After the Nail Falls Off
The bare nail bed is a small wound until it toughens up. Treat it like one:
- 1Wash it gently with lukewarm water and mild soap once a day, removing any dirt or debris. Pat it dry.
- 2Keep it moist, not wet: a thin layer of petroleum jelly, which dermatologists suggest for minor wounds in place of antibiotic creams.
- 3Cover it with a clean, sterile dressing, changed daily and whenever it gets wet, until the nail bed has healed over.
- 4If it stays damp, soak the foot for 5 minutes a day in warm, salty water until the area is dry and scabby. Skip soaks if you have diabetes.
- 5Give it room: open-toed or roomy shoes, and cushioned cotton socks, so nothing presses on the bare nail bed.
- 6Check your tetanus protection if the nail was torn off on something dirty or rusty. If you are not sure you are up to date, call your doctor.
Avoid
- Picking at the edges or the scab
- Digging under the remaining nail with sharp objects
- Tight shoes, or tight dressings that squeeze the toe
- Long soaks if you have diabetes
Once it has dried over
- A light dressing or padding is still useful in closed shoes
- Keep the foot clean and dry, with fresh socks daily
- Let the new nail grow in without trimming its corners down
Wondering whether what you see is normal? What a healing nail bed usually looks like is covered in what a toe looks like after nail removal.
Signs of Infection After a Toenail Comes Off
| Usually normal | Possible infection: get it seen |
|---|---|
| Tenderness that eases day by day | Pain that is increasing instead of settling |
| A little dried blood at the edges in the first days | Pus, or thick, milky fluid from the nail area |
| A damp nail bed that dries and scabs over | A strong or bad smell |
| Mild swelling right after an injury | New or spreading redness, heat or swelling around the nail |
| Feeling well in yourself | Fever or chills, or a temperature of 100.4°F (38°C) or higher during chemotherapy |
With diabetes, poor circulation or a weakened immune system, do not wait to see if it settles. If your nail was removed by a clinician rather than falling off, the side-by-side guide to infection after toenail removal explains why the yellow film on a healing nail bed is usually not pus.
My Toenail Came Off: Will It Grow Back?
Usually, yes. The nail is made by tissue tucked under the skin at the base of the toe, and a nail falling off does not normally destroy it. Regrowth is slow, though: toenails take about 12 to 18 months to grow all the way out, roughly twice as long as fingernails. The month-by-month picture, including what the first sliver of new nail looks like, is in the toenail regrowth timeline.
Will it grow back normal?
Most new nails look normal, but some regrow differently, with a ridge or a changed shape. The odds of a lasting change rise when the nail bed was badly crushed or torn, when a nail stayed lifted for a long time (the longer the separation, the less likely new growth is to stay attached), and when fungus or psoriasis is still active. A fungal nail is only cured when healthy nail grows back from the base.
After being ripped off
A nail torn off in an accident usually grows back too, but the nail bed underneath may be cut, and the bone at the tip of the toe can break. Unrepaired damage to the nail bed can leave the new nail ridged or deformed, so have a torn-off nail with a deep cut, heavy bleeding or a possible fracture examined.
Toenails Falling Off After an Illness, Chemotherapy or Medication
After an illness
A fever or a virus can briefly stop nail growth. The nail later separates at the base, often on several fingers and toes at once. After hand, foot and mouth disease in children it is usually noticed 4 to 8 weeks after the illness. No treatment is needed beyond protecting the loose nails, and they regrow, because the nail-making tissue is intact.
During chemotherapy
Some chemotherapy, taxanes in particular, can make nails lift and separate, with or without pain. Changes usually show weeks or months into treatment. Toenails can take up to about a year and a half to regrow, and most new nails look normal.
A major cancer center's patient guide suggests these steps during treatment. Check each with your oncology team:
- Ask about cold packs on the hands and feet from about 15 minutes before each infusion until 15 minutes after
- Keep nails trimmed short with the edges filed smooth
- Soft, padded shoes with cushioned cotton socks; avoid tight footwear and long-distance walking or running
- Avoid hot soaks and hot tubs, and ask before any pedicure
- If nails are lifting, ask whether a nightly 15-minute soak in equal parts white vinegar and water is right for you
Other medicines that can loosen nails include retinoids, some antibiotics (some only in strong sunlight), anti-inflammatory painkillers, lithium and some seizure medicines. Most nail changes improve once the drug is stopped, but do not stop a prescribed medicine on your own; talk to whoever prescribed it.
Diabetes, Neuropathy or Poor Circulation
A loose toenail or a bare nail bed is an opening in the skin of the foot. With diabetes, nerve damage can stop you feeling it, and a foot sore can get infected and heal poorly. So the rules change:
- •Have a loose or lost toenail looked at promptly rather than managing it alone
- •Do not trim a loose nail yourself if it is thick, hard to reach or hard to see
- •Skip foot soaks, including salt water; wash, then dry carefully, including between the toes
- •Check both feet every day, with a mirror or a helper if needed, even if they feel fine
- •Do not wait for your next appointment if you see a blister, sore, ulcer or ingrown toenail
Fungal nails, which often lift and loosen, also warrant a doctor's visit when you have diabetes. More in diabetic foot and wound care.
Keeping It From Happening Again
Shoes and mileage
Shoes that are not too small or tight at the toes, and a gradual build-up when you start walking or running more than usual.
Nail care
Trim straight across and file sharp edges smooth. Keep nails short if they tend to lift, and do not share clippers.
Fungus
Clean, dry feet and fresh socks, flip-flops in shared showers, and athlete's foot treated early before it spreads to the nails.
If fungus is the cause, see over-the-counter toenail fungus treatments compared for what works and how long it takes.

Frequently Asked Questions
Should I pull off a loose toenail?
No. Pulling on a nail that is still attached tears the nail bed it is stuck to, opens a raw wound, and damage to the nail bed can leave the new nail ridged or misshapen. Instead, trim the loose part back to where it is still attached, using clean clippers, or tape it flat so it cannot catch on socks. If it hurts too much to trim, or you have diabetes or poor circulation, let a podiatrist do it.
My toe nail came off, will it grow back?
Usually, yes. As long as the nail-making tissue under the skin at the base of the toe is intact, a new nail grows in. It is slow: a toenail takes about 12 to 18 months to grow all the way out, so the big toe takes the longest. Keep the bare nail bed clean and covered until it has dried and scabbed over, and wear roomy shoes while the new nail comes through.
Will my toenail grow back normal after falling off?
Most do. After an injury, a shed nail after an illness, or fungus that has been properly treated, the new nail usually looks normal, though some come in ridged or a slightly different shape. The chance of a lasting change goes up when the nail bed was badly crushed or torn, when a nail stayed lifted for a long time, or when fungus or psoriasis is still active.
Will my toenail grow back after being ripped off?
Usually, yes, but have it checked if it was torn off in an accident. A ripped-off nail can come with a cut in the nail bed underneath, or a broken bone at the tip of the toe. A clinician can clean it, decide whether it needs an X-ray or a repair, and check your tetanus protection. Damage to the nail bed is the main reason a new nail grows in ridged or misshapen.
What are the stages of a toenail falling off?
First comes the trigger: an injury, repeated shoe pressure, fungus, psoriasis, an illness or a medicine. Then the nail starts to lift, showing as a white, yellow or dark area where it has separated, or a line across the nail near the base. Next it turns loose and catches on socks. Finally it comes away, leaving a tender nail bed that dries and scabs over while a new nail grows in from the base.
Why is my toenail turning black and falling off?
Usually because blood collected under the nail after an injury, or after repeated pressure from tight shoes or more walking or running than usual. The blood lifts the nail off its bed, so it often loosens and comes off, and a new nail grows in its place. If there was no injury, the dark color is a streak, or it spreads onto the skin around the nail, have it checked, because not every dark nail is blood.
How do I care for my toe after the toenail falls off?
Wash it gently with mild soap and lukewarm water, apply a thin layer of petroleum jelly, and cover it with a clean dressing, changed daily, until the nail bed has healed over. If the nail bed stays damp, a five-minute soak in warm salty water once a day can help it dry, but skip soaks if you have diabetes. Wear roomy shoes, and watch for redness, heat, swelling, pus or a bad smell.
