Ingrown Toenail Home Treatment: What Helps and What to Avoid

What is actually happening with an ingrown toenail?

An ingrown toenail occurs when the edge or corner of the nail — most often the big toe — grows down into the soft skin (nail fold) alongside it. The nail pressing against the skin causes pain, tenderness, and redness. If bacteria enter through the irritated skin, the area can become infected, producing warmth, increased swelling, pus, and sometimes a small mound of overgrown tissue (granulation tissue).

What can I do at home for a mild ingrown toenail?

These steps are appropriate when the toe is sore and slightly red but not infected (no pus, no fever, no spreading redness):

1. Soak the foot Soak the affected foot in warm water for 15 to 20 minutes, two to four times per day. This softens the nail and the surrounding skin, reduces discomfort, and makes the nail easier to manage.

2. Gently lift the nail edge After soaking, while the skin is soft, try to gently wedge a small piece of dental floss, a cotton wisp, or a commercially available nail separator between the nail edge and the skin. This can help guide the nail to grow over rather than into the skin. Do not dig aggressively or cut a "V" into the nail — these folk remedies do not work and can worsen the problem.

3. Trim straight across When trimming the nail after soaking, cut straight across rather than rounding the corners. Leave the nail long enough that the corner extends just beyond the skin edge.

4. Choose appropriate footwear Wear shoes with a wide, roomy toe box that does not press the toes together. Avoid tight hosiery. Open-toed shoes or sandals can help while the nail is healing.

5. Keep the area clean After each soak, dry the foot thoroughly, including between the toes. Applying a thin layer of antibiotic ointment and a bandage can protect the area from minor abrasion.

What doesn't work (and what can make it worse)?

• Cutting a notch or "V" into the center of the nail does not reduce pressure at the sides and is not an effective remedy
• Cutting the nail too short encourages the skin to fold over the nail corner
• Digging under the nail edge with a sharp object risks breaking the skin and introducing infection
• Tightly wrapping the toe restricts blood flow without helping the nail grow correctly

When does a podiatrist need to be involved?

Home care is appropriate for mild, early cases, but a podiatrist is the right specialist for:

• Signs of infection: pus, spreading redness, warmth, or fever
• Recurring ingrown toenails: the nail grows in repeatedly in the same place despite proper care
• Severe pain that prevents normal walking or sleep
• Diabetes, peripheral arterial disease, or impaired circulation: even minor foot wounds can become serious, and home treatment is not advisable without clinician clearance
• A granuloma or tissue overgrowth at the nail edge

A podiatrist can perform a simple in-office procedure (partial nail avulsion) to remove the offending nail edge. When the nail repeatedly grows back in, a small amount of phenol can be applied to the nail root to prevent regrowth in that area. Evidence suggests that procedures addressing the nail root have significantly lower recurrence rates than simple nail trimming alone 1Ref 1Eekhof JAH, Van Wijk B, Knuistingh Neven A, van der Wouden JC (2012).Interventions for ingrowing toenails.Evidence basis for nail procedures versus simple trimming, and recurrence outcomes with different treatment approaches2Ref 2Exley V, Jones K, O'Carroll G, Watson J, Backhouse M (2023).A systematic review and meta-analysis of randomised controlled trials on surgical treatments for ingrown toenails part I: recurrence and relief of symptoms.Surgical treatments addressing the nail root have significantly lower recurrence rates than simple nail edge removal.

How can I prevent ingrown toenails from coming back?

• Trim nails straight across, not rounded, and keep them at a moderate length
• Choose shoes with adequate toe box width for your foot
• Protect the toes during sports and activities with appropriate footwear
• If you are a runner, ensure your shoes have enough length — toenails absorb repetitive pressure during long runs
• If you have a naturally curved nail shape, discuss preventive options with a podiatrist
