Nail fungus is often thought of as an adult problem; however, it can affect children, too. Although fungal nail infections are less common in kids than in adults, nail fungus in children is nevertheless a real concern, particularly for active kids who spend time barefoot, swimming, or sharing shoes and sports equipment.

Because children’s nails grow quickly and their immune systems are still developing, early recognition and proper treatment are especially important. For this reason, this guide explains how nail fungus affects children, in addition to the signs to watch for and the treatment options that are safe and effective.

Can Children Really Get Nail Fungus?

Yes, children can develop nail fungus. However, even though the risk is lower than in adults, fungal infections can still occur at any age.

For instance, children are more likely to get nail fungus when they:

  • Walk barefoot in public areas, such as pools, locker rooms, and gyms
  • Regularly participate in sports that cause sweaty feet
  • Frequently share shoes, socks, or nail tools
  • Already have athlete’s foot that then spreads to the nails
  • Experience minor nail injuries that ultimately allow fungus to enter

Ultimately, once fungus gets under the nail, it can be difficult to eliminate without proper treatment.

Signs of Nail Fungus

Parents should watch for the following common symptoms:

  • First, yellow, white, or brown discoloration of the infected nails
  • Additionally, thickening of the nails
  • In many cases, brittle, peeling, or crumbling nail edges
  • Sometimes, smelly debris under the nail
  • Over time, changes in nail shape
  • In more advanced cases, nail lifting from the nail bed
  • Occasionally, mild discomfort or pressure in closed-toe shoes

Because children may not complain about nail changes, for this reason, regular foot and nail checks are strongly recommended by our doctors.

Why Early Treatment Matters for Kids

First, addressing nail fungus early is especially important in children. For example, without treatment, the infection can:

  • Spread to other nails

  • Become thicker and harder to treat

  • Causes discomfort as the nail grows

  • Increase the risk of secondary skin infections

  • Affect a child’s confidence or willingness to participate in physical activities

Finally, early treatment is often simpler and more effective because children’s nails grow faster than adults’.

Are Over-the-Counter Treatments Safe for Children?

Over-the-counter antifungal creams or lacquers may help very mild infections; however, they have limitations:

  • First, they often can’t penetrate thick nails

  • Second, daily application can be difficult to maintain with children

  • Lastly, results are slow and inconsistent

Consequently, due to these challenges, parents often seek professional guidance when nail fungus persists.

Professional Treatment Options for Nail Fungus in Children

Treatment depends on the child’s age, severity of infection, and overall health.

Topical Treatments

  • Sometimes recommended for the mildest cases

  • Require consistent daily use

  • Limited effectiveness for thicker nails

Oral Antifungal Medications

  • Rarely prescribed for children

  • May involve potential side effects

  • Require careful medical supervision

Laser Nail Fungus Treatment

Laser therapy is increasingly used for pediatric nail fungus because it is:

  • Non-invasive

  • Medication-free

  • Quick and comfortable

  • Safe for most children

  • Effective at targeting fungus under the nail

Laser treatment allows children to return to school and activities immediately, with no downtime.

How Parents Can Help Prevent Nail Fungus

Prevention plays a key role in keeping children’s nails healthy. Furthermore, parents can help by encouraging:

  • Wearing flip-flops or water shoes in public areas

  • Keeping feet clean and dry

  • Changing socks daily

  • Wearing breathable shoes

  • Avoid sharing shoes or nail tools with other children

  • Treating athlete’s foot promptly

As a result, good habits reduce the risk of infection and reinfection.

When to See a Podiatrist

Parents should seek professional evaluation if they notice:

  • Persistent nail discoloration

  • Thick or brittle nails

  • Nail lifting or crumbling

  • Multiple nails affected

  • No improvement after home or OTC treatments

As a result of a good consultation, a foot doctor can confirm the diagnosis and recommend the safest and most effective treatment plan for your child.

Bottom Line: Nail Fungus in Children Requires Special Care

Although nail fungus is less common in kids, it should not be ignored. Additionally, Nail fungus in children requires careful evaluation and age-appropriate treatment to prevent progression and discomfort.

Furthermore, with early detection and modern treatment options, including laser therapy, children can safely restore healthy nail growth.
