Understanding Ingrown Toenails: What Happens and Why

An ingrown toenail occurs when the edge or corner of a toenail grows into the skin next to it, rather than over the top of the toe. This creates pressure, irritation, and often pain. The condition typically affects the big toe, though it can happen to any toenail. Medical professionals call this condition onychocryptosis.

The mechanics are straightforward: as the nail grows, its sharp edge pierces the surrounding skin and nail fold—the tissue that frames the nail. When this happens, your body responds like it would to any wound, triggering inflammation and sometimes infection. The area may become red, swollen, warm to the touch, and tender. In some cases, pus or fluid may drain from the site.

Several factors contribute to ingrown toenails developing. Improper nail trimming is one of the most common causes—cutting nails too short or at an angle rather than straight across encourages the edge to grow into skin. Wearing tight shoes or hosiery that puts pressure on toenails can also cause them, as can repetitive trauma from activities like running or kicking sports. Some people have a genetic predisposition to curved or thick toenails that are more prone to becoming ingrown.

Data from podiatric studies suggests that ingrown toenails affect roughly 10 percent of the population, with rates higher among teenagers and young adults. About 10 to 15 percent of people who develop ingrown toenails will experience them repeatedly. Understanding how ingrown toenails form helps you recognize early warning signs like mild discomfort, slight redness, or slight swelling before the condition becomes more serious.

Practical Takeaway: Ingrown toenails develop when nail edges grow into surrounding skin, typically from nail trimming technique or shoe pressure. Recognizing early redness or mild discomfort allows you to address the issue before significant pain or infection develops.

Prevention Strategies: Reducing Your Risk

Prevention is far more effective than treating an established ingrown toenail. Most prevention methods involve simple changes to daily habits and grooming practices. The foundation of prevention is proper nail trimming technique. Dermatologists recommend trimming toenails straight across rather than curved, keeping the edges even with the tip of the toe. This means your nail should extend just slightly past the edge of the toe itself. Never trim nails too short—they should be long enough that you can feel the nail edge when you run your finger over it.

The tools you use matter as well. Use sharp nail clippers specifically designed for toenails, not fingernail clippers or scissors. Dull tools can crush the nail edge rather than creating a clean cut, which increases the risk of problems developing. After trimming, smooth any sharp edges with a nail file. Trim your toenails when they're dry, as wet nails are softer and more likely to tear unevenly. Most experts recommend trimming every four to six weeks or whenever nails become noticeably long.

Footwear choices significantly impact ingrown toenail risk. Shoes that crowd the toes—whether too tight overall or too narrow in the toe box—put constant pressure on nails and skin. Choose shoes with adequate space so you can wiggle your toes slightly. Your big toe should have at least a quarter-inch of space between it and the shoe's end. Avoid shoes with excessively pointed toe boxes. When breaking in new shoes, do so gradually rather than wearing them for extended periods immediately. Moisture can soften skin and nails, making ingrown toenails more likely, so keep feet dry and change socks if they become damp.

Protective measures during activities matter too. If you play sports involving foot contact or repetitive stress—like soccer, ballet, or running—wear properly fitting athletic shoes designed for that activity. Consider extra padding or toe protection if you've had problems before. Avoid stubbing your toes when possible, as trauma can trigger ingrown toenails in vulnerable nails.

Practical Takeaway: Trim toenails straight across with sharp tools, keep them slightly longer than the toe edge, wear shoes with adequate toe space, and keep feet dry. These straightforward changes reduce ingrown toenail risk substantially.

Early Care and Home Management Options

When you first notice signs of an ingrown toenail—mild discomfort, slight redness, or minor swelling—several home care approaches may help prevent the condition from worsening. Early intervention can sometimes stop progression before professional treatment becomes necessary. The goal during this stage is to reduce inflammation, keep the area clean, and prevent infection.

Soak your foot in warm water for 15 to 20 minutes, three to four times daily. This softens the skin and reduces inflammation. Some people add a small amount of salt to the water—about one tablespoon per gallon—or use Epsom salt, though evidence supporting salt's effectiveness is limited. After soaking, gently pat the area dry. Never leave it wet, as moisture promotes infection. You can apply over-the-counter pain relievers like ibuprofen or acetaminophen to manage discomfort, following package directions.

Keep the area scrupulously clean using mild soap and water. After cleaning and drying, you might try gently lifting the nail edge away from the skin using a clean, flat object—some people use a tiny splinter of wood or a specialized tool designed for this purpose. The goal is to encourage the nail to grow over the skin rather than into it. Only do this if the area isn't too painful or swollen. If the skin is significantly inflamed or if you see signs of infection (increasing warmth, spreading redness, pus, or warmth), stop and consider professional care.

Wear open-toed shoes, sandals, or shoes that don't put pressure on the affected toe whenever possible. Some people find temporary relief using cotton wedges or special nail braces that physically separate the nail from the skin fold, though evidence on their long-term effectiveness varies. If you choose to try these products, replace them regularly and keep the area clean.

Watch for infection signs: increasing pain, spreading redness, warmth that spreads beyond the immediate area, pus, or discharge with odor. People with diabetes, circulation problems, or immune system conditions should be particularly cautious, as infections in these populations can become serious quickly.

Practical Takeaway: Home care—warm soaks, careful cleanliness, pain management, and shoe modifications—may help prevent early ingrown toenails from progressing. However, if signs of infection appear or pain increases despite home care, professional evaluation is appropriate.

Professional Treatment Options Available

When home care isn't sufficient or the ingrown toenail is already causing significant pain or shows infection signs, several professional treatments exist. A podiatrist or dermatologist can evaluate the toe and recommend the most appropriate approach for your situation. Treatment options range from minor office procedures to more involved surgical approaches, depending on severity.

For mild to moderate ingrown toenails without infection, a healthcare provider might perform a simple lifting procedure. The provider numbs the toe, then gently lifts the nail edge and places material underneath it—often a splint, dental floss, or specialized material—to keep it separated from the skin as it grows. This allows the nail to grow over the skin rather than into it. This approach works best when done early and requires follow-up care to replace the separating material as the nail grows.

Partial nail removal is another common approach for recurring or problematic ingrown toenails. Under local anesthesia, the provider removes the problematic portion of the nail—usually just the corner edge that's causing trouble. This reduces the nail's width and eliminates the portion growing into skin. The procedure takes about 15 to 30 minutes in an office setting. The nail regrows over several months. Recurrence rates vary but are generally lower than with lifting procedures alone.

For severe, repeatedly recurring ingrown toenails, a provider might recommend removing the nail root on the affected side. This is called a matrixectomy. The provider removes the nail portion and also destroys the root cells on that side so the nail never regrows in that location. This is usually combined with partial nail removal. The toe functions normally after healing, though the nail is narrower on one side. This approach has the lowest recurrence rate, typically under 5 percent.

After any professional procedure, proper wound care is essential. Your provider will give specific instructions
