Toenail Falling Off? What to Do and When to See a Podiatrist

Toenail Falling Off? Don’t Panic But Don’t Ignore It Either

You’ve just noticed your toenail is lifting, discoloured, or has fallen off entirely. The immediate reaction is usually a mixture of alarm and revulsion, followed by frantic Googling. Take a breath. A toenail falling off is more common than you think, and in most cases, it’s manageable. But understanding what to do next and when professional help is needed makes all the difference between smooth healing and complications.

Why Toenails Fall Off

Trauma

The most common cause. Dropping something on your toe, stubbing it hard, or repetitive microtrauma (common in runners and footballers) can damage the nail bed, causing blood to collect under the nail (subungual haematoma) and eventually causing the nail to detach.

Fungal infection

Advanced fungal infections can cause the nail to thicken, crumble, and eventually separate from the nail bed. The nail may lift gradually over weeks or months.

Runner’s toe

Repetitive impact from the toe hitting the front of the shoe during running, particularly downhill, causes bruising and eventual nail loss. Black toenails are practically a rite of passage in distance running.

Psoriasis and other skin conditions

Nail psoriasis can cause pitting, thickening, and separation of the nail from the nail bed. Other skin conditions can have similar effects.

Immediate First Aid: What to Do

• If the nail is partially detached, do not pull it off let it fall away naturally to protect the sensitive nail bed underneath
• Clean the area gently with soap and warm water
• Apply an antiseptic and cover with a clean, dry dressing to protect the exposed nail bed
• Wear open-toed shoes or shoes with ample room to avoid pressure on the affected toe
• Keep the area clean and dry, changing dressings regularly

How to Prevent Toenail Loss

• Wear properly fitting shoes with adequate toe room there should be roughly a thumb’s width between your longest toe and the end of the shoe
• Keep toenails trimmed to an appropriate length not too long (catches and tears) and not too short (exposes the nail bed)
• For runners: ensure running shoes are half a size larger than your normal shoes to account for foot swelling during exercise
• Treat fungal infections early before they can progress to nail detachment
• Protect toes during sport with appropriate footwear

When to See a Podiatrist

Seek professional help if there’s significant pain, bleeding, or signs of infection (redness, swelling, pus, warmth). If the nail loss is caused by a fungal infection, professional treatment is needed to address the underlying condition. If you’re uncertain about the cause or the nail bed looks abnormal, a podiatrist can assess and advise. For cosmetic concerns, we offer nail reconstruction to restore the appearance of the nail whilst the new one grows.
