Most mild ingrown fingernails can be treated at home with warm soaks, a topical antibiotic, and careful nail care over the course of a few days. The key is softening the nail and skin, gently freeing the embedded edge, and keeping the area clean while it heals. If the skin around your nail is hot, swollen, or oozing pus, that signals an infection that likely needs professional treatment.
What Causes Ingrown Fingernails
Ingrown fingernails happen when the edge of the nail curves into the surrounding skin fold, causing pain, redness, and swelling. They’re less common than ingrown toenails, but the triggers are different. Nail biting is one of the biggest culprits: it tears the nail unevenly and can expose the underlying tissue to bacteria. Cutting nails too short or rounding them too aggressively gives the nail edge a chance to dig into the skin as it grows back.
Trauma plays a role too. Jamming your finger, compulsive picking, or using your nails as tools (prying things open, scraping surfaces) can deform how the nail grows. Overzealous manicures are another common cause. Pushing back cuticles too aggressively, rough removal of artificial nails, or frequent application and removal of nail polish can weaken the nail plate and change its growth pattern. Even habitual finger-tapping can contribute over time.
How to Treat It at Home
For a mild ingrown fingernail with some redness and tenderness but no signs of infection, home treatment is straightforward. Start by soaking the affected finger in warm water for 15 to 20 minutes, two to three times a day. This softens both the nail and the surrounding skin, making it easier to work with and reducing pain.
After soaking, try to gently lift the nail edge away from the skin. You can use a clean, thin piece of cotton or dental floss tucked under the corner of the nail to encourage it to grow over the skin rather than into it. Replace the cotton daily after each soak to keep the area clean. This technique takes patience. You may need to repeat it for several days before the nail edge clears the skin fold.
Once you’ve soaked and repositioned the nail, apply an over-the-counter topical antibiotic ointment to the area. A topical corticosteroid cream can also help if inflammation is significant. Cover the finger with a small bandage to protect it. Avoid tight rings or gloves that press on the nail while it heals.
Signs of Infection That Need Attention
An ingrown nail that goes untreated can develop into a condition called paronychia, a bacterial infection of the skin around the nail. The warning signs are distinct: the skin becomes red, warm to the touch, and increasingly swollen. Pain intensifies rather than improving. You may notice pus building up under the skin near the nail, sometimes forming a visible white or yellow abscess.
If an abscess forms, it often won’t drain on its own. A healthcare provider will numb the area, make a small incision, and drain the pus. You may also need a course of antibiotics if the infection has spread beyond the immediate nail area. Don’t try to lance or squeeze an abscess yourself, as this can push bacteria deeper into the tissue.
When You Need a Professional Procedure
If home treatment doesn’t resolve the problem after a week or so, or if the ingrown nail keeps coming back, a minor in-office procedure can fix it. The most common approach is a partial nail avulsion, where the provider numbs your finger with a local anesthetic and removes the strip of nail that’s digging into the skin. The procedure itself takes only a few minutes.
For recurring ingrown nails, the provider may also treat the nail matrix (the tissue at the base of the nail that produces new growth) to prevent that section of nail from growing back. This is called a matricectomy. One common method uses a chemical agent applied to the matrix after the nail edge is removed. Healing time with this approach is typically under two weeks, and recurrence rates are low.
If a partial nail removal was performed, expect about six to eight weeks for full healing. A complete nail removal takes eight to ten weeks. During recovery, you’ll redress the wound every other day with antibiotic ointment and a fresh bandage until the area has fully closed.
How to Trim Your Nails to Prevent Recurrence
The way you cut your fingernails matters more than most people realize. The American Academy of Dermatology recommends cutting almost straight across the nail, then using a nail file or emery board to slightly round the corners. This keeps nails strong and prevents the sharp edges that catch on clothing or curl into skin. Don’t cut them too short. Leave enough white tip that you can’t see skin peeking over the edge.
Use the right tools. Nail clippers or nail scissors designed for fingernails work best. Avoid tearing nails with your teeth or pulling off hangnails by hand. If you get manicures, don’t let the technician push your cuticles back aggressively or use harsh chemicals for removing artificial nails. Cuticles protect the nail matrix from bacteria, and damaging them increases your risk of both ingrown nails and infection.
If you’re a nail biter, that habit is probably the single biggest thing to address. Biting creates jagged, uneven edges that are far more likely to grow into the surrounding skin. It also introduces bacteria from your mouth directly into any small breaks in the skin around your nails, setting the stage for infection.
