What Is Toenail Fungus (Onychomycosis)?

Toenail fungus, medically known as onychomycosis, is a fungal infection that affects approximately 10% of the general population and up to 50% of adults over age 70. The condition develops when fungi—most commonly dermatophytes, but also yeasts and molds—penetrate beneath the nail and begin growing in the warm, moist environment of the nail bed.

​

The infection typically starts as a white or yellow spot under the tip of the toenail. As it progresses, the nail becomes thickened, discolored, brittle, and may separate from the nail bed. Left untreated, toenail fungus rarely resolves on its own and can spread to other toenails, fingernails, and surrounding skin.

 

Common signs of toenail fungus include:

  • Yellow, brown, or white discoloration of the nail

  • Thickened, distorted nail shape

  • Brittle, crumbly, or ragged nail edges

  • Foul odor from the affected nail

  • Pain or discomfort when wearing shoes

  • Nail separating from the nail bed (onycholysis)

Why Is Toenail Fungus So Difficult to Treat?

Traditional treatments for toenail fungus have significant limitations. Topical antifungal medications penetrate nail tissue poorly, resulting in success rates of only 10-25%. Oral antifungal medications like terbinafine show higher effectiveness (60-70%) but require 3-6 months of daily medication and carry risks of liver toxicity, drug interactions, and gastrointestinal side effects.

 

The fungal organisms live beneath the nail plate in the nail bed, protected by the hard keratin of the nail itself. This creates a physical barrier that prevents most treatments from reaching the infection at therapeutic concentrations.

How Does Laser Therapy Treat Toenail Fungus?

At DMV Foot & Ankle, Dr. Alex Mattia uses Class IV laser therapy to treat toenail fungus through a process called selective photothermolysis. The laser emits specific wavelengths of light energy that penetrate through the nail plate and are absorbed by the fungal organisms and pigmented debris beneath the nail.

 

The laser treatment works through multiple mechanisms:

 

Thermal Destruction: The laser energy heats the fungal cells to temperatures that denature their proteins and destroy their cellular structure. The nail tissue, having different optical properties, absorbs less energy and remains undamaged.

 

Disruption of Fungal Reproduction: Even fungal cells that aren't immediately destroyed suffer damage to their reproductive mechanisms, preventing the infection from spreading.

 

Stimulation of Immune Response: Laser therapy triggers a localized immune response that helps the body fight the remaining infection more effectively.

What Are the Benefits of Laser Therapy Over Traditional Treatments?

Laser therapy for toenail fungus offers several significant advantages compared to oral and topical antifungal medications:

 

No Systemic Side Effects: Unlike oral antifungals that must be processed by your liver, laser therapy works directly on the affected area. There are no drug interactions, no need for blood monitoring, and no risk of liver toxicity.

 

Higher Success Rates: Clinical studies demonstrate 70-85% improvement rates with laser therapy, compared to 60-70% for oral medications and 10-25% for topical treatments. When combined with proper nail care and hygiene protocols, success rates can exceed 90%.

 

Quick Treatment Sessions: Each laser session takes approximately 20-30 minutes for all affected toenails. Most patients require 3-4 treatment sessions spaced 4-6 weeks apart.

 

No Downtime: Patients can immediately resume normal activities, including wearing shoes and exercising, after treatment. There is no recovery period required.

Pain-Free Procedure: Most patients describe the sensation as a warming feeling. No anesthesia is required, and discomfort is minimal.

What Should You Expect During Treatment?

Before Your Appointment: Dr. Mattia will conduct a thorough evaluation of your toenails to confirm the diagnosis of onychomycosis. This may include visual examination, nail culture, or microscopic analysis to identify the specific fungal organism.

 

During Treatment: You'll recline comfortably while the laser handpiece is passed over each affected nail in a specific pattern. The treatment delivers precise energy to the nail bed while a built-in cooling system keeps the surrounding skin comfortable.

 

Sessions typically last 5-15 minutes depending on the number of nails treated.

After Treatment: You can put your shoes back on and return to normal activities immediately. Dr. Mattia will provide detailed instructions for nail care and hygiene practices that maximize treatment success.

How Long Until You See Results?

It's important to understand that existing damaged nail cannot be repaired—you are waiting for healthy, clear nail to grow out. Toenails grow approximately 1mm per month, meaning complete nail turnover takes 9-12 months.

 

Typical timeline:

  • Weeks 1-4: No visible change (new nail growth just beginning)

  • Months 2-3: Clear, healthy nail visible at the nail base

  • Months 4-6: Approximately 50% clear nail growth

  • Months 9-12: Complete clear nail in most patients

 

Most patients notice the first signs of improvement (clear nail growing from the base) within 2-3 months after beginning treatment.

Who Is a Good Candidate for Laser Therapy?

Laser therapy is appropriate for most patients with toenail fungus. You may be an excellent candidate if:

  • You have mild to moderate toenail fungus

  • You cannot take oral antifungal medications due to liver conditions, drug interactions, or other health concerns

  • You've tried topical treatments without success

  • You prefer a treatment option without systemic medications

  • You want faster, more predictable results

 

Conditions that may affect treatment:

  • Severe nail dystrophy may require longer treatment courses

  • Patients with diabetes or peripheral vascular disease may need additional precautions

  • Active bacterial infections should be treated before beginning laser therapy

 

​Dr. Mattia will evaluate your specific situation during your consultation to determine if laser therapy is the right choice for your condition.

Frequently Asked Questions

How many laser treatments will I need?

Each treatment package includes 3 laser sessions spaced 4-6 weeks apart. This applies to both our single toenail package ($750) and multiple toenails package ($1,000).

 

Is laser treatment for toenail fungus painful?

Most patients experience only a warm sensation during treatment. No anesthesia is required, and discomfort is minimal.

 

How soon can I paint my nails after laser treatment?

We recommend waiting 24-48 hours before applying nail polish. When you do resume polish, use antifungal nail polish or apply antifungal treatment underneath regular polish.

 

Will the fungus come back after laser treatment?

Laser therapy eliminates the current infection, but it doesn't prevent future reinfection. Following proper prevention protocols significantly reduces recurrence risk.

 

Can I wear shoes immediately after treatment?

Yes, you can put on shoes and resume all normal activities immediately after your laser session.

 

Does insurance cover laser treatment for toenail fungus?

Most insurance plans consider laser therapy for toenail fungus a cosmetic procedure. However, HSA and FSA funds can typically be used for treatment. Our all-inclusive pricing is $750 for a single toenail or $1,000 for multiple toenails, which covers all 3 treatment sessions.

 

How do I know if I have toenail fungus or something else?

Conditions like psoriasis, trauma, and bacterial infections can mimic toenail fungus. Dr. Mattia will confirm your diagnosis through examination and, if needed, laboratory testing before recommending treatment.
