How to Cure Toenail Fungus: Causes, Remy Laser Treatment, and FAQs

Toenail fungus (Onychomycosis) is one of the most frustrating conditions we treat. It usually starts as a tiny white or yellow spot under the tip of the nail. If ignored, it rapidly progresses, leaving you with thick, brittle, discolored, and sometimes painful toenails.

While treating an established fungal infection takes time, the good news is that we have advanced, non-surgical tools to clear the infection and restore the look of your foot. At Prime Podiatry, we want you to stop hiding your feet in heavy shoes. Here is what you need to know about how you caught the fungus, how we destroy it, and how to keep it from coming back.

The Top 4 Causes of Toenail Fungus

Fungi thrive in warm, dark, and moist environments. Understanding how the infection takes root is the first step in protecting your feet.

1. Damp, Sweaty Feet

If you work in heavy boots or sweat heavily in non-breathable sneakers, your shoes become an incubator for fungal spores.

• Prevention: Wear moisture-wicking synthetic or wool socks. Rotate your shoes daily to ensure they dry out completely before you wear them again.

2. Walking Barefoot in Public Areas

Public swimming pools, gym locker rooms, and communal showers are massive hot spots for fungal infections and warts.

• Prevention: Never walk barefoot in these environments. Always wear a protective barrier like shower shoes or flip-flops.

3. Micro-Trauma and Nail Injuries 

Dropping something on your toe, stubbing it, or simply wearing tight shoes that constantly bang against your nails creates tiny micro-cracks in the nail plate.

• These microscopic openings give fungal spores a direct pathway into the nail bed.
• Prevention: Always wear properly fitted shoes with a thumb’s width of space in the toe box!

4. Sharing Contaminated Tools

 Using someone else’s nail clippers or visiting a nail salon that fails to properly sterilize its instruments easily transfers fungus from person to person.

• Prevention: Bring your own tools to the salon and never share clippers with family members who have an active infection.

The Medical Solution: The Remy Class IV Laser

If you have tried drugstore antifungal lacquers, you already know they rarely work. The hard keratin of your nail plate acts as a shield, preventing weak topical creams from reaching the infection underneath.

To bypass this barrier, we utilize the Remy Class IV Laser.

• How It Works: The Remy Laser emits focused light energy that passes safely through the nail plate. It heats and destroys the fungal cells living in the nail bed without harming the surrounding healthy tissue.
• The Benefits: It is a 20-minute, completely non-invasive procedure. There are no needles, zero downtime, and it avoids the potential liver toxicity associated with heavy oral antifungal medications.

The Aesthetic Solution: KeryFlex Nail Restoration

The Remy Laser effectively kills the fungus, but human biology is slow. It can take 6 to 12 months for a completely healthy new toenail to grow from the cuticle to the tip!

• You do not have to hide your feet for a year while you wait. We offer the KeryFlex Nail Restoration System!
• In a single visit, we apply a medical-grade, breathable resin over your damaged nail.
• This creates an instantly beautiful, natural-looking, and flexible artificial nail that allows the healthy nail to grow unobstructed underneath. 
• You leave the office ready for sandals!

Frequently Asked Questions (FAQs)

Can toenail fungus go away on its own? 

No. Toenail fungus is a progressive infection. It will not clear up without medical treatment, and waiting only allows it to spread to your other toes.

Is the Remy Laser treatment painful? 

No. Most patients report a gentle, warm tingling sensation during the procedure. It requires no anesthesia, and you can return to work or the gym immediately.

How many laser sessions will I need? 

While every patient is different, most clear their infections with 3 to 5 laser sessions spaced a few weeks apart. We will design a personalized roadmap for your specific condition.

Will the fungus come back?

 The laser kills the current infection, but it does not make you immune to future fungal spores. Maintaining foot hygiene and sanitizing your shoes is the only way to prevent reinfection.
