Ingrown toenails are one of the most common foot problems we treat in podiatry — and one of the most frequently mismanaged at home. Whether you're dealing with a mildly sore big toe or a red, swollen nail border that's making it hard to walk, this guide covers what's actually happening, when you can treat it yourself, and when it's time to see a podiatrist.
What is an ingrown toenail?
An ingrown toenail (onychocryptosis) occurs when the edge or corner of a toenail grows into the surrounding skin, causing pain, swelling, and sometimes infection. It most commonly affects the big toe, though any toenail can become ingrown.
The nail doesn't technically "grow inward" — it follows its normal growth path, but the skin fold at the nail border gets compressed or pierced by the nail edge. This can happen because the nail is too wide for the nail bed, the nail has been cut incorrectly, or external pressure (tight shoes, injury) has pushed skin into the nail's path.
What causes ingrown toenails?
Understanding the cause matters because it determines whether home treatment will work or whether you'll keep getting them back. The most common causes are:
- Incorrect nail cutting — the number one cause. Cutting nails too short, rounding the corners, or tearing nails instead of cutting them cleanly leaves sharp edges or spicules that dig into the skin as the nail grows forward.
- Tight or narrow footwear — shoes that compress the toes push the skin fold against the nail edge. Pointed-toe shoes, too-small shoes, and tight socks all contribute. This is why ingrown toenails are more common in people who wear dress shoes or work boots daily.
- Nail shape and genetics — some people naturally have wider, more curved nails (involuted nails) that are predisposed to growing into the skin. If your parents had recurring ingrown toenails, you're more likely to as well.
- Trauma or injury — stubbing your toe, dropping something on it, or repetitive microtrauma from sport (runners, soccer players) can damage the nail or surrounding skin, triggering an ingrown episode.
- Sweaty feet — excessive moisture softens the skin around the nail, making it easier for the nail edge to penetrate. This is why ingrown toenails are more common in teenagers and young adults with active sweat glands.
- Picking or tearing nails — pulling at loose nail edges instead of cutting them cleanly almost always leaves a sharp spicule that embeds into the skin within days.
Stages of an ingrown toenail
Ingrown toenails progress through recognisable stages. Knowing which stage you're in helps determine whether home treatment is appropriate or whether you need professional care.
Stage 1 — Mild (inflammation only)
The nail border is tender and slightly red. The skin may be swollen where it meets the nail edge, and it hurts when you press on it or wear tight shoes. There's no pus, no significant swelling, and the pain is manageable. Home treatment is usually effective at this stage.
Stage 2 — Moderate (infection developing)
The redness and swelling have increased. You may notice the skin growing over the nail edge (hypertrophy), and there may be some clear or yellowish discharge. The pain is more constant — not just when pressed. See a podiatrist if it hasn't improved within a few days of home treatment.
Stage 3 — Severe (established infection)
Significant swelling, redness that extends beyond the immediate nail fold, pus discharge, and pain that affects walking. The tissue may have formed granulation tissue — a raised, red, moist lump alongside the nail that bleeds easily. Do not attempt to treat this at home. See a podiatrist or doctor promptly.
Home treatment for mild ingrown toenails
If your ingrown toenail is at Stage 1 — mild tenderness and redness without infection — you can try managing it at home before seeking professional help.
Warm salt water soaks
Soak the affected foot in warm (not hot) water with a tablespoon of table salt or Epsom salt for 15–20 minutes, twice daily. This softens the skin, reduces swelling, and helps the nail edge separate from the irritated tissue. Pat the toe dry thoroughly afterward — moisture makes things worse.
Gently lift the nail edge
After soaking, when the skin is soft, you can try gently lifting the embedded nail edge away from the skin using a clean, thin implement (a flat nail file or the blunt end of a toothpick). If you can get a small piece of clean cotton or dental floss under the nail edge, it can help train the nail to grow over the skin rather than into it. Change the cotton daily.
Protect the toe
Use a Hapla Tofoam tube ($9.95) to cushion the affected toe and reduce pressure from footwear. The foam sleeve creates a barrier between the sore nail fold and the shoe, reducing friction and giving the area space to settle. For more protective options, see our guide to toe protectors and separators.
Wear open or wide-fitting shoes
Switch to open-toed sandals or shoes with a wide, deep toe box while the toe is inflamed. Any pressure on the nail fold will slow healing. Avoid tight socks as well.
What NOT to do
Do not attempt "bathroom surgery" — digging into the nail fold with scissors, nail clippers, or other tools is the most common cause of ingrown toenail infections we see in clinic. Do not cut a V-shape into the top of the nail (this is a myth — it does nothing, since nails grow from the root, not the tip). Do not apply strong antiseptics repeatedly, as they can irritate already-inflamed tissue.
When to see a podiatrist
You should see a podiatrist or doctor if:
- Home treatment hasn't improved the pain and swelling within 3–5 days
- There's any sign of infection — pus, increasing redness, warmth, or red streaks extending from the toe
- You have diabetes, poor circulation, or peripheral neuropathy (even a mild ingrown toenail needs professional management — the infection risk is significantly higher). Read more about nerve and circulation issues in the feet.
- The ingrown toenail keeps coming back — recurring episodes usually mean the nail shape or width needs permanent correction
- There's granulation tissue (a raised, red, bleeding lump) alongside the nail
What happens at the podiatrist — ingrown toenail surgery
The word "surgery" sounds dramatic, but ingrown toenail surgery is a straightforward, in-office procedure performed under local anaesthetic. It's one of the most common procedures in podiatry and takes about 30–45 minutes including anaesthetic time.
Partial nail avulsion (PNA)
This is the standard treatment for recurring or moderate-to-severe ingrown toenails. The podiatrist numbs the toe with a local anaesthetic injection, then removes only the offending edge of the nail — not the whole nail. The nail matrix (growth cells) at the removed edge is then treated with a chemical called phenol, which permanently prevents that narrow strip of nail from growing back. The rest of the nail continues to grow normally.
The result is a nail that looks almost identical to before, just slightly narrower — and the ingrown edge doesn't return. Success rates for PNA with phenolisation are above 95%.
Total nail avulsion
In rare cases where the entire nail is severely damaged, infected, or deformed, the podiatrist may remove the whole nail. This is uncommon for standard ingrown toenails and is usually reserved for nails with extensive fungal nail infection or significant trauma damage.
Recovery after ingrown toenail surgery
Most people walk out of the clinic in open-toed shoes. The toe will be bandaged and may ooze for a few days. You'll need to:
- Keep the toe clean and dry, redressing it daily with a simple non-adherent dressing
- Use Hypafix adhesive retention tape to secure dressings — it stays put without wrapping around the whole toe
- Avoid closed shoes for 1–2 days, then transition to wide, comfortable footwear
- Soak the toe in warm salt water daily from day 2 onward to keep the wound clean
- Expect full healing in 4–6 weeks, though pain typically resolves within a few days
You can usually return to normal activities within a day or two. High-impact sport should wait 2–3 weeks until the wound has closed over.
How to prevent ingrown toenails
Prevention comes down to two things: how you cut your nails and what shoes you wear.
How to cut toenails correctly
This is the single most important thing you can do to prevent ingrown toenails:
- Cut straight across — do not round the corners. The corners of the nail should be visible above the skin fold, not trimmed down into it.
- Don't cut too short — the nail should extend just past the tip of the toe. If you can see the skin of the nail bed in front of the nail edge, you've cut too short.
- Use proper nail clippers or nail nippers — not scissors, and never tear or pick at nails. Straight-edge clippers give the cleanest cut.
- Cut after bathing — nails are softer and less likely to splinter or crack.
- File any sharp edges — after clipping, gently file the corners with an emery board to remove any rough spots that could catch on skin.
Footwear that prevents ingrown toenails
Your shoes should have enough room in the toe box that you can wiggle your toes freely. When buying shoes, shop in the afternoon (feet swell throughout the day) and always have at least a thumb's width of space between your longest toe and the end of the shoe. Avoid pointed-toe styles if you're prone to ingrown toenails.
If you wear work boots or steel-cap shoes daily, make sure they're properly fitted — safety footwear that's too short or too narrow is a very common cause of recurring ingrown toenails in tradespeople.
Protect vulnerable toes
If you know you're prone to ingrown toenails — perhaps after surgery, or if you have naturally curved nails — using a Hapla Tofoam tube on the affected toe during sport or when wearing tighter footwear can prevent the nail fold from being compressed against the nail edge.

Ingrown toenails in children and teenagers
Ingrown toenails are extremely common in teenagers, partly because of rapid foot growth (shoes become too small quickly), increased sweating, and often because they haven't learned proper nail cutting technique. Parents should check shoe fit regularly and teach straight-across cutting early. If a child has a painful, swollen toe, don't dismiss it — untreated ingrown toenails in children can become seriously infected and affect their willingness to be active.
Frequently asked questions
Can an ingrown toenail heal on its own?
A very mild ingrown toenail (Stage 1 — slight tenderness, no infection) can sometimes resolve on its own if the cause is removed — for example, switching from tight shoes to wider footwear. However, most ingrown toenails that are causing noticeable pain will need at least some home treatment (soaking, lifting the nail edge, protecting the toe). If there's any sign of infection or the pain is worsening, it will not heal without professional treatment.
How long does an ingrown toenail take to heal?
A mild ingrown toenail treated at home can improve within 1–2 weeks. After podiatric nail surgery (partial nail avulsion), pain typically resolves within a few days, and the wound heals completely in 4–6 weeks. Without treatment, an infected ingrown toenail will not heal on its own and will usually get progressively worse.
Does ingrown toenail surgery hurt?
The procedure itself is painless — it's performed under local anaesthetic. The anaesthetic injection can sting briefly, but once the toe is numb, you won't feel anything. Post-operative pain is usually mild and manageable with over-the-counter pain relief for a day or two. Most patients report that the post-surgery pain is significantly less than the pain the ingrown toenail was causing.
Will an ingrown toenail come back after surgery?
Partial nail avulsion with phenolisation has a success rate above 95% — meaning in most cases, the treated nail edge does not grow back. In the small percentage of cases where regrowth occurs, the procedure can be repeated. Without chemical treatment of the nail matrix (a simple nail removal without phenol), the recurrence rate is much higher.
Should I put antiseptic on an ingrown toenail?
For a mild ingrown toenail, warm salt water soaks are preferable to strong antiseptics like Betadine or Dettol, which can irritate inflamed skin. If there are signs of infection, a podiatrist may prescribe or recommend a specific antiseptic or antibiotic. Don't self-treat an infected ingrown toenail with antiseptic alone — it needs professional assessment.
Is it safe to get a pedicure with an ingrown toenail?
If the ingrown toenail is actively inflamed or infected, avoid pedicures — the tools used can worsen the condition or introduce bacteria. Once the nail has healed, let the pedicurist know about your history so they can avoid cutting the corners too aggressively. Better yet, cut your own toenails straight across and use the pedicure for cosmetic work only.
