While nail problems are more frequently associated with adults, children can and do experience both ingrown toenails and fungal nail infections. Paediatric nail health is often influenced by factors specific to childhood, such as rapid growth spurts, high levels of physical activity, and developing hygiene habits. Although fungal infections are statistically less common in younger children than in the older population, they can still occur, particularly if the child has regular exposure to communal damp areas. Understanding these conditions in the context of childhood development allows parents and carers to implement appropriate protective measures and ensure that minor nail issues are managed before they lead to discomfort or localised infection.

The prevalence of ingrown toenails in children
Ingrown toenails are a common occurrence in children and are frequently seen during the teenage years when growth is most rapid. In younger children, the nail plate is often softer and more flexible than in adults, which might seem to offer protection; however, this flexibility can also allow the nail to be easily pushed into the skin fold. The most frequent cause in this age group is incorrect nail trimming, where the corners are cut too deep or rounded off, allowing the skin to bulge over the growing nail edge.
Teenagers often develop ingrown nails due to a combination of growth spurts and footwear choices. As feet grow quickly, shoes that were comfortable a few months prior can become tight, putting significant mechanical pressure on the toes. The NHS website highlights that ingrown toenails are a common foot problem for people of all ages, including children, and are often caused by tight shoes or incorrect trimming. Ensuring that children have adequate room in their shoes and are taught correct grooming habits is essential for preventing this painful condition.
Fungal nail infections in the paediatric population
Fungal nail infections, or onychomycosis, are less common in prepubescent children than in adults, but the incidence increases as children move into adolescence. One reason for the lower rate in younger children is the faster rate of nail growth, which can sometimes allow the child to grow out an infection before it becomes well-established. However, children who participate in swimming or other sports involving communal showers are at a higher risk of picking up fungal spores from damp floors.
In children, a fungal infection often manifests as a change in the colour or texture of the nail, similar to the symptoms seen in adults. Because children’s nails are naturally thinner, the fungus can sometimes spread more quickly across the nail plate. Clinical knowledge summaries suggest that while fungal infections are less frequent in children, they should be formally diagnosed to ensure that the treatment is safe and appropriate for the child’s age. Maintaining dry feet and using waterproof footwear in public areas are the most effective ways to lower this risk for active children.
The impact of growth spurts and footwear
The rapid rate at which children’s feet grow presents a unique challenge for nail health. A child may outgrow their shoes several times a year, and the resulting pressure from a tight toe box can cause immediate damage to the nails. This pressure can lead to subungual haematomas, where blood pools under the nail, or it can force the nail into the surrounding skin fold. It is vital for parents to regularly check the fit of their children’s shoes, ensuring there is always a thumb-width of space at the end.
Active children who play high-impact sports like football or rugby are particularly vulnerable to nail trauma. The repetitive striking of the ball or the foot hitting the front of the boot can cause the nail to thicken or become brittle over time. Choosing sports-specific footwear that is properly fitted and using moisture-wicking socks can help to cushion the toes and maintain a healthy environment for the nails, even during intensive physical activity.
Paediatric hygiene and grooming habits
Teaching children correct nail care and hygiene from a young age is a fundamental preventative measure. Nails should always be trimmed straight across, and any sharp corners should be gently smoothed with a fine file rather than being cut away. It is also important to encourage children to dry their feet thoroughly after bathing, especially between the toes, to prevent the damp conditions that facilitate fungal and bacterial growth.
As children become more independent with their hygiene, they should be reminded not to share socks, shoes, or grooming tools with their peers. For children who suffer from excessively sweaty feet, a condition known as hyperhidrosis, changing socks twice a day and using absorbent foot powders can help to keep the nails dry and resilient. These simple daily habits reinforce the nail natural barriers and significantly reduce the likelihood of developing chronic nail problems as they grow.
Distinguishing between infection and other nail changes
It is important to recognize that not all nail changes in children are due to infection. For example, some children develop temporary white spots on their nails, known as leukonychia, which are usually the result of minor trauma to the nail matrix and will grow out naturally. Other children may have nails that appear slightly spoon-shaped, a condition called koilonychia, which can be normal in infancy but may sometimes indicate a nutritional deficiency if it persists.
However, if a child’s nail becomes persistently discoloured, thickened, or if the skin around the nail is red and painful, these are signs that a clinical issue may be present. Monitoring the nails during the weekly hygiene routine allows for the early detection of these changes. If you are unsure whether a nail change is normal or a sign of infection, seeking a professional review can provide clarity and ensure that any necessary treatments are started promptly.
When to seek a professional clinical review
You should consult a GP or a podiatrist if a child’s nail problem is causing pain, shows signs of infection-like pus or spreading redness, or does not improve with basic home care. Professional management is particularly important for ingrown nails that have become infected, as a clinician can safely clear the edge and treat the underlying inflammation. They can also provide expert advice on the best products and footwear for a child’s developing feet.
Seeking professional help is also advised if a child has a recurring nail problem, as this may indicate an underlying issue with their footwear or foot structure. A podiatrist can perform a full assessment and may suggest specific lacing techniques or orthotics to help redistribute pressure. Clinical care ensures that paediatric nail issues are managed safely and effectively, allowing the child to remain active and comfortable as they continue to grow.
Conclusion
Children can suffer from both ingrown nails and fungal infections, though the causes often differ from those in adults. Rapid growth and incorrect trimming are primary drivers of ingrown edges, while communal sports areas can facilitate fungal spread. Consistent hygiene and regular footwear checks are essential for maintaining paediatric nail health. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
How can I tell if my child’s shoes are too tight for their nails?
If there is no space to wiggle the toes or if you see redness on the tips of the toes after they take their shoes off, the shoes are likely too small.
Is it safe to use adult antifungal cream on a child?
You should always consult a pharmacist or GP before using any medicated treatments on a child to ensure the product is safe for their age.
Why does my child keep getting ingrown toenails?
This is often due to a combination of fast-growing feet and the common habit of cutting the nail corners too short or rounding them off.
Can a child catch a fungal infection from a school changing room?
Yes, damp communal floors are a common site for the transmission of fungal spores, so wearing flip-flops is a good preventative measure.
Should I be worried about white spots on my child’s nails?
Small white spots are usually just a sign of minor knocks to the nail and will disappear as the nail grows out over a few months.
What is the best way to dry a child’s feet to prevent infection?
Use a clean towel and pay extra attention to the areas between the toes or use a hairdryer on a cool setting for a few seconds.
Can nail-biting lead to infections in children?
Yes, biting the nails can damage the protective skin around the nail and introduce bacteria from the mouth, leading to painful infections.
