A toenail that has been completely removed will usually grow back, provided the nail matrix, the tissue at the base of the nail responsible for producing new nail cells, has not been permanently destroyed. Full regrowth of a toenail takes roughly 12 to 18 months in most adults, considerably longer than fingernails. Whether the new nail comes in looking normal or grows back thickened, ridged, or misshapen depends heavily on what caused the removal and what condition the underlying nail bed is in.
Why the Matrix Is What Matters
The nail matrix is a crescent of tissue tucked beneath the skin at the base of your toe. Every new layer of toenail is generated there. When a toenail is pulled off by trauma, removed by a doctor, or falls off on its own, the matrix stays behind in most cases and simply starts producing a fresh nail plate. As long as this tissue is alive and intact, regrowth is the default outcome.
Doctors sometimes deliberately destroy the matrix, most commonly when treating severe or recurring ingrown toenails. A chemical called phenol is applied to the matrix after removing part or all of the nail, killing the cells so that the offending section of nail never returns. One study comparing partial nail avulsion with and without phenol treatment found that recurrence of the ingrown nail was dramatically lower when phenol was used, with only about 1.4% of patients seeing the problem return, compared to 10% of those who had the nail removed without matrix destruction.
1PubMed Central. Comparison of Partial Nail Avulsion With or Without Phenolization in the Management of Ingrown ToenailsThat difference highlights a key distinction: removal of the nail plate alone is temporary, while destruction of the matrix is designed to be permanent. If your doctor performed a matrixectomy (matrix destruction) as part of your procedure, that portion of the nail is not expected to grow back, and that is the intended result.
How Long Regrowth Takes
Toenails grow far more slowly than fingernails. A fingernail typically replaces itself in about six months, while a toenail needs somewhere between 12 and 18 months, sometimes longer. The big toenail, being the largest, usually sits at the upper end of that range. Smaller toenails on the fourth and fifth toes can finish sooner simply because there is less nail to produce.
Growth rate also varies by person. Younger people tend to see faster regrowth. Blood circulation matters too: the toes are the furthest point from the heart, and anyone with reduced blood flow to the feet, whether from diabetes, peripheral artery disease, or simply aging, may find regrowth takes well over a year. During winter months, when circulation to the extremities naturally decreases, growth can slow even further.
The earliest visible sign of regrowth is usually a thin, slightly opaque strip of nail emerging from beneath the cuticle area. It often looks different from the old nail at first. The new plate may be thinner, more flexible, or slightly discolored. These features tend to improve as the nail matures, but it can take the full 12 to 18 months before you can judge the final result.
Trauma and What It Means for the New Nail
Toenails get knocked off in all kinds of ways: stubbing a toe hard, dropping something heavy on it, distance running, or having a door slam on a foot. The severity of the underlying injury makes a real difference in what grows back. A study of nail bed injuries found that outcomes were poorer when the damage involved crush injuries, avulsion injuries, or injuries to the nail fold, and that the presence of a fracture in the bone beneath the nail was associated with worse results overall.
2Annals of Plastic Surgery. Anylasis of Nail Bed Injuries: Cause, Outcome, TreatmentThis makes intuitive sense. If a heavy object merely pops the nail off its bed without damaging the underlying tissue, regrowth tends to proceed normally. But if the same impact crushes the nail bed or fractures the distal phalanx (the small bone at the tip of the toe), the matrix and bed can scar as they heal, and the new nail may grow in ridged, split, or permanently thickened.
When a nail bed injury is significant, the nail plate often needs to be removed so a doctor can inspect and repair the bed underneath. Clinical guidance on nail trauma recommends exploration and repair when the nail plate itself is damaged, when a fracture involves the germinal matrix, or when the bone fracture needs stabilization.
3PubMed Central. Approach to nail trauma for primary care physiciansGetting the bed stitched back together cleanly during that initial window gives the future nail the best surface to adhere to and grow along. Skipping that repair, or having it done poorly, raises the chance of a permanently abnormal nail.
Removal for Ingrown Toenails
Ingrown toenails are one of the most common reasons a toenail gets removed in a clinical setting. The procedure is usually a partial avulsion, meaning the doctor removes only the offending strip of nail along one side, not the entire plate. With partial removal and no matrix destruction, that strip of nail grows back in a few months, which is fine if the ingrown problem was a one-time event but frustrating if it recurs.
For people with recurring ingrown nails, phenolization of the matrix along the affected edge is the standard next step. A systematic review of randomized trials found that procedures using phenol were associated with lower pain scores compared to other surgical options for ingrown toenails.
4PubMed Central. A systematic review and meta-analysis of randomised controlled trials of surgical treatments for ingrown toenails part II: healing time, post-operative complications, pain, and participant satisfactionThe trade-off is a slightly narrower nail going forward, since the destroyed strip of matrix will not produce nail again. Most people consider this a worthwhile exchange for ending the cycle of pain and infection.
Children present a special case. In kids younger than ten, soft tissue-focused procedures are generally preferred over aggressive matrix destruction, because the growing nail and toe are still developing, and permanent narrowing of the nail plate or distortion of its shape is a bigger concern in a foot that has decades of use ahead of it.
5Dermatologic Surgery. Pediatric Ingrown Toenails: A Practical Treatment AlgorithmWhen Fungal Infections Are Involved
Toenail fungus, especially when it is severe or has resisted topical treatments, is another situation where a doctor might recommend removing the nail entirely. The idea is to strip away the infected nail plate so that antifungal medication can work directly on the nail bed, and then a clean, uninfected nail grows in to replace it.
Results vary, and the success of this approach depends on following up with antifungal treatment consistently during the many months of regrowth. In one study of patients whose toenail fungus followed a single traumatic event, nail avulsion combined with both oral and topical antifungals led to a healthy regrowing nail in the majority of cases: 34 out of 39 treated digits grew back with a healthy-looking nail.
6PubMed Central. Post-Traumatic Single-Digit OnychomycosisThat is an encouraging number, but it came with months of dedicated treatment, including topical ciclopirox for at least nine months and oral terbinafine for four to six months. In a separate randomized trial looking at surgical avulsion combined with topical therapy alone, overall mycological cure was achieved in about 56% of patients, and no long-term complications from the avulsion itself were observed.
7British Journal of Dermatology. Combination of surgical avulsion and topical therapy for single nail onychomycosis: a randomized controlled trialThe takeaway is that the nail itself tends to grow back fine after removal for fungal reasons. The harder problem is making sure the fungus does not return along with it. Recurrence of toenail fungus is notoriously common, especially in older adults, people with diabetes, and anyone whose feet spend a lot of time in warm, moist environments.
Retronychia and Other Regrowth Complications
Sometimes the nail starts growing back but does not do so smoothly. One condition worth knowing about is retronychia, where the newly growing nail plate pushes backward into the proximal nail fold instead of gliding forward over the nail bed the way it should. This causes the fold to become swollen, painful, and inflamed, and it can be confusing because it looks a lot like an infection or an ingrown nail, just at the wrong end of the toe.
8PubMed Central. RetronychiaRetronychia is associated with situations that stress the nail, including repetitive trauma (think long-distance runners and hikers), poor blood flow, and the postpartum period. Multiple generations of nail plate can stack up beneath the nail fold, compounding the problem. It was only formally described in 1999 and is still underrecognized, so if you have persistent swelling at the base of a regrowing toenail that is not responding to antibiotics, retronychia is a possibility your doctor should consider.
9PubMed. Retronychia of the toenails: a review with emphasis on pathogenesis, new diagnostic and management trendsOther regrowth problems include nails that come in permanently thickened (a condition called onychauxis), nails with ridges or splits running lengthwise, and nails that lift away from the bed as they grow (onycholysis). These outcomes are more likely when the original injury was severe, when the nail bed was not repaired, or when an underlying condition like psoriasis or lichen planus is affecting the nail unit. A retrospective study on nail lichen planus found that nail bed involvement was common, with onycholysis appearing in over a third of patients.
10PubMed Central. Clinical features and treatment outcomes of nail lichen planus: A retrospective studyTaking Care of a Toe After Nail Removal
The exposed nail bed is tender, raw, and vulnerable for the first few weeks. It is essentially a wound, and treating it like one is the right approach. Your doctor will usually apply a non-stick dressing, and you will need to keep the area clean, dry, and protected while the bed forms a thin protective layer of skin. Most people can walk immediately after the procedure, but the toe is sore, and closed-toed shoes may be uncomfortable for a week or two.
Soaking the foot in warm, mildly salty water once or twice a day for the first week or so helps keep the wound clean without disturbing healing tissue. Avoid pulling off any scabbing or dried blood. Infection is a real risk during the first couple of weeks, so watch for increasing redness, swelling, warmth, or pus. People with diabetes or poor circulation should be especially vigilant, because healing in the toes is already compromised in those situations, and a minor wound infection can escalate quickly.
Once a thin skin layer has formed over the bed, usually within two to three weeks, the toe becomes much less sensitive. Wearing shoes is comfortable again, and you can resume normal activity. The nail plate that is slowly emerging will be fragile and easily snagged for months, so trimming it very short and wearing socks that do not catch on it is a practical habit until the nail has matured.
Nail Removal for Tumors and Growths
Occasionally a toenail is removed not because of the nail itself but because of a growth underneath it. Glomus tumors, for example, are small benign tumors that develop in the nail bed and cause intense, often disproportionate pain, especially in response to cold or pressure. Removing the nail plate is necessary to access and excise the tumor, and the question of whether the nail grows back normally afterward is understandably a concern.
A case report documenting nail-preserving excision of a glomus tumor in a toe described lifting the nail, making an incision in the nail bed to remove the encapsulated mass, repairing the bed with fine sutures, and then repositioning the original nail plate. The nail was successfully restored with no wound scar and no recurrence of the tumor.
11PubMed Central. Nail-preserving excision of glomus tumor in the second toe: Case report and literature reviewNot every nail surgery goes this smoothly, but this approach, where the surgeon preserves as much of the nail unit as possible and repairs the bed carefully, gives the best chance of a cosmetically normal outcome. For malignant growths under the nail, the calculus is different: removing enough tissue to clear the cancer takes priority, and cosmetic nail outcomes become secondary.
Conditions That Can Prevent or Impair Regrowth
A few situations can lead to a nail that never fully returns or that regrows so abnormally it is essentially non-functional:
- Severe matrix scarring: A deep crush injury, a bad burn, or frostbite that scars the matrix tissue can permanently stop nail production in the affected area. The nail may grow back only partially, or with a permanent split.
- Intentional matrix destruction: As discussed above, phenol or surgical excision of the matrix is done deliberately to prevent regrowth. This is not a complication but a planned outcome.
- Peripheral vascular disease: Very poor blood supply to the toes can slow or halt regrowth entirely. In advanced cases, the tissue simply does not have the resources to produce a nail.
- Autoimmune skin conditions: Diseases like lichen planus or severe psoriasis can attack the nail matrix and bed, leading to scarring that impairs or prevents normal nail production even after the underlying condition is treated.
Age alone does not prevent regrowth, but it does slow it and increases the likelihood of a cosmetically imperfect result. Older adults often find that their regrowing toenails are thicker, more brittle, and slightly yellow compared to their original nails. Nutritional status has been proposed as a factor, though the evidence is not always clear-cut. One cross-sectional study comparing nail zinc levels in older adults with and without nail changes found no statistically significant difference between the groups, even after adjusting for common conditions like diabetes and high blood pressure.

Most of the time, a toenail that has been removed will quietly and uneventfully grow back on its own. But a few signs during regrowth deserve professional attention. Persistent pain or swelling at the base of the nail after the first few weeks could indicate retronychia or infection. A new nail growing in with a dark streak, especially one that is irregular or expanding, warrants evaluation to rule out subungual melanoma, a rare but serious form of skin cancer that arises under the nail. And a nail that has not shown any visible regrowth after three to four months may indicate matrix damage that was not obvious at the time of removal.
If you had your toenail removed for fungal reasons and the new nail starts showing signs of discoloration or thickening again, that likely means the fungus was not fully eradicated. Catching it early in the regrowth phase, when the new nail is thin and antifungal treatments can penetrate more effectively, gives you a better shot at a clean outcome than waiting until the nail has fully grown in and the fungus has reestablished itself underneath.
