An ingrown toenail happens when the edge or corner of a nail — almost always on the big toe — grows into the surrounding skin instead of over it, causing pain, redness, and swelling. Mild cases often respond well to careful at-home care, but nails that become infected or keep recurring need a podiatrist's attention. Below, our team walks through daily habits that prevent ingrown nails, how to manage a mild one at home, and the warning signs that mean it's time to come in.
What causes an ingrown toenail?
Ingrown nails have a few common causes, and they often overlap:
- Improper trimming — cutting nails too short or rounding the corners instead of trimming straight across
- Tight or narrow footwear that crowds the toes and presses the nail into the skin
- Trauma to the toe, such as stubbing it or dropping something on it
- Nail shape or thickness — naturally curved nails are more prone to growing inward
- Sweaty feet or poor foot hygiene, which softens the skin around the nail
Older adults may face additional challenges, including thicker nails and reduced flexibility that make trimming and daily foot checks harder to manage independently. Younger, active people more often run into trouble from improper trimming or tight athletic shoes.
Daily habits that prevent ingrown toenails
Most ingrown nails are preventable with a consistent care routine. Our podiatrists recommend building these habits into your day:
- Check your feet daily. Use a mirror if needed to look for redness, swelling, or changes in your nails, especially if you have diabetes or reduced sensation in your feet.
- Wash and dry thoroughly. Clean your feet with mild soap in lukewarm water, and dry completely — especially between the toes — to keep skin from softening and breaking down.
- Trim nails straight across. Avoid rounding the corners or cutting too short, which encourages the nail to grow into the skin.
- Choose shoes with adequate toe room. Tight, narrow, or pointed shoes put constant pressure on the nail.
- Wear cushioned, moisture-wicking socks and avoid walking barefoot in places where your toes can get stubbed or injured.
Nutrition also plays a supporting role — a diet rich in lean proteins, whole grains, fruits, and vegetables, along with adequate calcium, vitamin D, and biotin, supports the immune system and tissue repair that keep skin and nails healthy.
How to care for a mild ingrown toenail at home
If the toe is only mildly red or tender, with no drainage or spreading infection, home care can often help:
- Soak the foot in warm water for 15–20 minutes, two to three times a day, to soften the skin and ease discomfort
- After soaking, gently lift the edge of the nail away from the skin — never dig into the corner or attempt "bathroom surgery" with sharp tools
- Keep the area clean and covered with a bandage if needed
- Wear roomy, open-toed shoes or sandals while the toe heals
- Take an over-the-counter pain reliever if needed for discomfort
If the toe hasn't improved within a few days of consistent home care, it's time to have it looked at rather than continuing to manage it on your own.
When should you see a podiatrist?
Some ingrown nails need professional treatment rather than home care. See a podiatrist promptly if you notice:
- Redness that is spreading beyond the nail fold
- Pus or drainage from the area
- A foul odor coming from the toe
- Persistent, sharp, or worsening pain
- Fever, or red streaking up the foot — signs of a more serious infection
People with diabetes or poor circulation should never try to manage an ingrown nail at home and should be seen promptly, since even minor foot injuries can become serious more quickly. For nails that keep recurring, a simple in-office procedure can permanently narrow the nail border and prevent future ingrown nails. We recommend at least an annual podiatry visit for routine nail and foot care, with more frequent visits if you have recurring issues.
