An infected ingrown toenail can usually be treated at home with warm soaks and proper nail care, as long as the infection is mild. When the skin around your toenail is red, swollen, and tender but not oozing pus or spreading redness up your toe, home treatment is a reasonable first step. More advanced infections, especially those with discharge or worsening pain, need professional care.
Recognizing a Mild vs. Serious Infection
A mild infection looks like redness and swelling along one side of the toenail, with tenderness when you press on it or wear shoes. The skin may feel warm to the touch. At this stage, the infection is still localized and responds well to home care.
A serious infection has progressed beyond that. You may notice pus draining from the nail fold, increasing redness that spreads beyond the immediate area, or throbbing pain that doesn’t improve with rest. Fever, chills, red streaks running away from the toe, or a rapid heart rate are signs the infection has moved into deeper tissue. This type of spreading infection (cellulitis) can, in rare cases, reach the bone or bloodstream. If you notice any of these systemic symptoms, you need medical attention right away.
Home Treatment for Early Infections
Warm soaks are the cornerstone of home care. Mix 1 to 2 tablespoons of unscented Epsom salt into one quart of warm water and soak your foot for 15 minutes. Do this several times a day for the first few days. The warm water softens the skin and nail, reduces swelling, and helps draw out any early buildup of fluid. After each soak, dry your foot thoroughly.
Once the skin is softened, you can try gently lifting the edge of the ingrown nail away from the skin using a small piece of clean cotton or dental floss tucked underneath. This encourages the nail to grow over the skin rather than into it. Replace the cotton daily, ideally after a soak when the tissue is most pliable. Apply an over-the-counter antibiotic ointment and cover with a clean bandage.
While treating the nail, wear open-toed shoes or shoes with a wide toe box. Tight footwear presses the nail further into the skin and keeps the area warm and moist, which is exactly what bacteria thrive on. Keep the area clean and dry between soaks.
When You Need Antibiotics
If the infection doesn’t improve within two to three days of consistent home treatment, or if pus is already present when you first notice the problem, oral antibiotics are typically necessary. Your doctor will choose an antibiotic based on the bacteria most likely causing the infection, usually staph or strep species. In areas where drug-resistant staph infections are common, a different antibiotic class may be prescribed based on local resistance patterns.
Antibiotics treat the infection itself, but they don’t fix the underlying ingrown nail. That’s why antibiotics alone rarely solve the problem permanently. If the nail edge is still embedded in the skin, the infection often returns once you stop the medication.
What Happens During a Procedure
For ingrown toenails that keep coming back or don’t respond to conservative treatment, a minor in-office procedure is the most effective solution. The most common approach is partial nail avulsion: your doctor numbs the toe with a local anesthetic, then removes the sliver of nail that’s digging into the skin. The whole thing takes about 20 minutes, and you walk out on your own.
To prevent the nail from growing back into the same spot, your doctor may apply a chemical (usually phenol) to the exposed nail root. This destroys the small strip of cells responsible for growing that edge of the nail. A large Cochrane review found this combination to be significantly more effective than removing the nail strip alone. In one comparison, only 1 in 25 patients who had the chemical treatment experienced a recurrence, versus 8 in 21 without it. Across multiple studies, chemical matrixectomy produces success rates above 95%, with recurrence rates between 1% and 4% over follow-up periods of six months to nearly three years.
The cosmetic result is subtle. You lose a thin sliver along one edge of the nail, so the toenail ends up slightly narrower than before, but most people barely notice the difference.
Recovery After a Procedure
Most people return to work or school the next day. The toe will be sore and bandaged, and you’ll need to keep it clean and dry while it heals. If part of the nail was removed, expect six to eight weeks for full healing. If the entire nail was removed (which is less common), healing takes eight to ten weeks.
During recovery, avoid swimming and reduce strenuous physical activity until the site has fully closed. You’ll likely change the dressing at home for the first couple of weeks, keeping the area covered with antibiotic ointment. Some drainage and mild soreness during the first week are normal. Pain that gets worse after the first few days, or new redness spreading around the toe, warrants a follow-up visit.
Preventing Ingrown Toenails From Returning
The single most important prevention habit is cutting your toenails straight across rather than rounding the corners. Curved cuts leave short edges that can dig into the skin as the nail grows forward. Keep nails at a moderate length, roughly even with the tip of the toe. Cutting them too short encourages the surrounding skin to fold over the nail edge.
Footwear matters more than most people realize. Shoes that squeeze the toes together, especially pointed dress shoes and narrow athletic shoes, press the nail into the skin fold repeatedly throughout the day. If you’re prone to ingrown nails, choosing shoes with a roomy toe box can make a noticeable difference. The same goes for socks: overly tight socks create the same compressive force.
People with diabetes, peripheral neuropathy, or poor circulation in their feet should be especially careful. Reduced sensation means you may not feel the early pain of an ingrown nail, and poor blood flow slows healing once an infection starts. Regular foot checks and professional nail care can prevent small problems from becoming serious ones.
