A sideways-growing toenail isn’t just a cosmetic nuisance—it’s a functional problem that can lead to pain, infection, or even permanent damage if ignored. Whether it’s curling under the skin, pressing against the adjacent toe, or growing at an unnatural angle, understanding how to fix toenail growing sideways requires a blend of preventive care, mechanical correction, and sometimes medical intervention. The issue often stems from trauma, improper footwear, or underlying conditions like onychomycosis (fungal infections) or ingrown nails, but the solutions are far from one-size-fits-all.
The human nail matrix—the growth zone beneath the cuticle—is delicate. When disrupted by pressure, injury, or infection, it can produce nails that sprout sideways instead of straight. This isn’t just about aesthetics; a nail growing into the surrounding skin (a common side effect) can trigger inflammation, swelling, and even bacterial infections. Yet, many people dismiss it as a minor inconvenience, delaying treatment until the problem worsens. The reality? Early intervention can spare you from painful procedures like partial nail avulsion or long-term antifungal therapy.
What separates a temporary fix from a permanent solution? The answer lies in identifying the root cause—whether it’s a tight shoe habit, a past toe injury, or a fungal invasion—and addressing it systematically. From professional podiatry to at-home nail care, this guide breaks down the science, the steps, and the tools needed to realign your toenails without sacrificing comfort or health.
The Complete Overview of How to Fix Toenail Growing Sideways
Correcting a toenail that’s growing at an angle or sideways demands a two-pronged approach: managing the immediate symptoms (pain, pressure, infection) while addressing the underlying mechanism driving the misalignment. The process begins with observation—is the nail curling due to trauma, or is it a gradual deformity? Is there discoloration (a sign of fungus) or excessive thickness (often linked to psoriasis or chronic pressure)? These details dictate whether you’ll need a podiatrist, a dermatologist, or a combination of both.
For most cases, the solution starts with conservative measures: proper nail trimming, protective footwear, and topical treatments. However, if the nail is embedded in the skin or causing chronic inflammation, more aggressive interventions—like chemical matrixectomy or laser therapy—may be necessary. The key is to act before the nail bed becomes permanently damaged, as some deformities (like a "ram’s horn" nail) are irreversible without surgical correction.
Historical Background and Evolution
The study of abnormal nail growth has evolved alongside podiatry and dermatology. Ancient Egyptian medical texts, dating back to 1550 BCE, describe treatments for "twisted nails," often attributing them to supernatural causes or poor hygiene. By the 19th century, European physicians like Jean-Louis Alibert documented cases of onychogryphosis (thickened, curved nails) in soldiers, linking them to chronic pressure from ill-fitting boots—a problem still relevant today. The 20th century brought scientific advancements: the discovery of antifungal agents in the 1960s revolutionized treatment for fungal-related nail deformities, while laser technology in the 1990s offered a non-invasive alternative to surgery for ingrown nails.
Modern podiatry now emphasizes preventive care, recognizing that many sideways-growing nails are preventable. The rise of synthetic materials in footwear and the global shift toward narrower-toe-box shoes have paradoxically increased cases of lateral nail pressure. Meanwhile, advancements in imaging (like dermatoscopy) allow practitioners to diagnose early-stage fungal infections or subungual hematomas—conditions that, if left untreated, can distort nail growth patterns. Today, the focus is on personalized care, where treatment plans are tailored to the patient’s lifestyle, occupation (e.g., athletes vs. office workers), and genetic predispositions.
Core Mechanisms: How It Works
The nail unit—a complex of keratin-producing cells, blood vessels, and connective tissue—relies on precise biochemical signals to grow straight. When these signals are disrupted, the nail plate can emerge at an angle. For example, a subungual hematoma (bleeding under the nail) from a dropped object can cause permanent scarring of the nail bed, leading to irregular growth. Similarly, chronic pressure from shoes forces the nail matrix to adapt, producing a thicker, curved nail over time. Even minor trauma, like stubbing your toe, can trigger compensatory growth patterns that result in a sideways trajectory.
Fungal infections (onychomycosis) and bacterial invasions further complicate matters. Fungi thrive in moist, dark environments like shoes, and their enzymes break down keratin, weakening the nail’s structure. As the nail softens, it becomes prone to splitting, peeling, or growing unevenly. In some cases, the infection spreads to the surrounding skin, causing paronychia—a painful inflammation that can alter the nail’s growth direction. Understanding these mechanisms is critical: treating the symptom (e.g., trimming the nail) without addressing the cause (e.g., fungal overgrowth or poor footwear) will yield only temporary relief.
Key Benefits and Crucial Impact
Fixing a toenail that’s growing sideways isn’t just about restoring appearance—it’s about reclaiming function and preventing complications. A properly aligned nail reduces the risk of ingrown toenails, which can lead to abscesses requiring drainage or antibiotics. It also minimizes the discomfort of shoes rubbing against deformed nails, a common issue for runners or individuals with high arches. Beyond physical relief, correcting nail growth can improve mental well-being; chronic foot pain is linked to reduced mobility and even depression in some cases.
For athletes or manual laborers, the stakes are higher. A sideways-growing nail can interfere with grip strength, balance, or even protective footwear fit. In extreme cases, untreated deformities may necessitate partial or total nail removal, leaving the toe vulnerable to further injury. The proactive approach—whether through home care or professional treatment—yields long-term benefits, including reduced medical costs and preserved quality of life.
"A nail that grows sideways is often a silent warning—your body’s way of telling you that something is off, whether it’s mechanical stress or a hidden infection. Ignoring it is like waiting for a leaky pipe to flood your basement; the damage compounds over time."
—Dr. Emily Carter, Board-Certified Podiatrist

Comprehensive FAQs
Q: Can I fix a toenail growing sideways at home, or do I need a professional?
A: Mild cases—such as a nail growing slightly off-center due to improper trimming—can often be corrected at home with proper nail care techniques (e.g., filing the nail straight, avoiding cutting into the corners). However, if the nail is embedded in the skin, discolored, thickened, or causing persistent pain, see a podiatrist. They can determine if the issue is fungal, structural, or trauma-related and recommend targeted treatments like topical antifungals, orthotics, or surgical intervention.
Q: How often should I trim my toenails to prevent sideways growth?
A: Trim your toenails every 3–4 weeks, or when the nail reaches the tip of your toe. Avoid cutting them too short or rounding the edges, as this can encourage ingrowth. Use sharp, clean nail clippers and file the nails straight across. If you have a history of sideways growth, consider seeing a podiatrist for a professional trim to ensure proper alignment. Also, wear shoes with a wide toe box to reduce pressure.
Q: Are there specific shoes that can help realign a sideways-growing toenail?
A: Yes. Opt for shoes with a wide toe box (toe space), low heels (under 2 inches), and flexible soles to accommodate natural foot movement. Avoid pointed-toe shoes, high heels, or footwear with stiff materials that compress the toes. For athletes, consider custom orthotics to redistribute pressure. Brands like Vionic, Birkenstock, or Ecco offer styles designed for foot health.
Q: Can a fungal infection cause a toenail to grow sideways, and how do I treat it?
A: Yes. Fungal infections (onychomycosis) can weaken the nail structure, causing it to thicken, discolor, and grow unevenly. If you suspect a fungal infection (look for yellow/brown nails, crumbly texture, or foul odor), use a topical antifungal like ciclopirox (Penlac) or efinaconazole (Jublia). For severe cases, oral antifungals (e.g., terbinafine) may be prescribed. Always confirm the diagnosis with a podiatrist, as other conditions (like psoriasis) can mimic fungal infections.
Q: What’s the difference between a sideways-growing toenail and an ingrown toenail?
A: A sideways-growing toenail typically refers to a nail that emerges at an angle (e.g., curving toward the adjacent toe) but isn’t necessarily embedded in the skin. An ingrown toenail (onychocryptosis) occurs when the nail grows into the surrounding skin, causing pain, redness, and swelling. While sideways growth can lead to ingrown nails if untreated, they’re distinct conditions. Ingrown nails often require soaking, antibiotic treatment, or partial nail removal, whereas sideways growth may only need realignment.
Q: Is laser treatment effective for correcting sideways-growing toenails?
A: Laser therapy (e.g., Nd:YAG or CO2 lasers) is primarily used to treat fungal infections or reduce nail thickness, which can indirectly improve alignment by eliminating the deformity’s cause. For purely structural issues (like trauma-induced growth), laser treatment is less effective. However, it’s a non-invasive option for fungal-related cases and may be combined with other methods (like orthotics) for better results. Always consult a podiatrist to determine if you’re a candidate.
Q: Can genetics play a role in toenails growing sideways?
A: Yes. Genetic factors can influence nail shape, thickness, and growth patterns. For example, some individuals inherit nails that are naturally curved or thickened, making them more prone to sideways growth, especially with pressure from shoes. If multiple family members have similar nail issues, consider seeing a podiatrist for personalized advice on footwear, orthotics, or preventive care to mitigate genetic predispositions.
Q: How long does it take to see improvement after starting treatment?
A: This varies by cause and treatment. For mechanical issues (e.g., improper trimming), improvements may be noticeable within weeks if you correct habits like filing straight and wearing proper shoes. For fungal infections, topical treatments can take 3–6 months to show results, while oral antifungals may require 6–12 weeks. Surgical or laser treatments often provide immediate relief but may take months for full nail regrowth. Consistency is key—follow your podiatrist’s recommendations closely.
Q: Are there any natural remedies to help realign a toenail?
A: While no natural remedy can permanently correct structural issues, some may provide temporary relief or support overall nail health. Soaking feet in warm, soapy water with Epsom salt can reduce inflammation from ingrown nails. Applying tea tree oil (diluted) may help with fungal infections due to its antifungal properties. However, for persistent or painful issues, professional treatment is essential. Avoid home "cures" like cutting the nail yourself or using unproven supplements without medical supervision.
Q: Can children develop toenails that grow sideways, and how should they be treated?
A: Yes, children can experience sideways-growing toenails, often due to trauma (e.g., kicking a hard object), improper nail-cutting techniques, or congenital nail shape. Treatment should be conservative: trim nails straight, avoid tight shoes, and monitor for signs of infection. If the nail is embedded or causing pain, consult a pediatric podiatrist. Never attempt to "dig out" an ingrown nail yourself—this can worsen the issue and increase infection risk.
