What Is Toenail Fungus (Onychomycosis)?

Onychomycosis is a fungal infection of the nail plate and nail bed, most commonly caused by dermatophyte fungi that thrive in warm, moist environments. It affects roughly 10% of the general population and up to 50% of adults over 70. Despite being extremely common, toenail fungus rarely resolves on its own — and tends to worsen and spread without treatment.

The infection typically begins as a small white or yellow spot under the tip of the nail. Over time, it spreads deeper into the nail, causing the nail to thicken, discolor, and become brittle. In advanced cases the nail may separate from the nail bed, emit an odor, and cause discomfort with footwear.

People with diabetes, peripheral vascular disease, or compromised immune systems face higher risk of serious complications from untreated nail fungus, including secondary bacterial infections. Early treatment matters.

Toenail fungus is not merely cosmetic. Left untreated it spreads to other nails and skin, and poses real health risks for patients with diabetes or circulatory conditions.

Signs of Toenail Fungus

Fungal nail infections progress through recognizable stages. The sooner treatment begins, the better the outcome.

🌹

Yellow or Brown Discoloration

The nail changes from its normal pinkish-white to yellow, brown, or white as the fungus colonizes the nail plate and disrupts normal keratin structure.

Thickened, Brittle Nail

Infected nails become noticeably thicker and harder to trim. They may crumble at the edges or break off in chunks rather than cutting cleanly.

Distorted Nail Shape

As the infection progresses, the nail loses its smooth, flat appearance and may curl, lift at the edges, or develop an irregular, ridged surface.

👀

Dark Debris Under the Nail

A buildup of dark, powdery material under the nail tip is a classic sign of onychomycosis. The debris consists of fungal elements and nail tissue fragments.

Nail Separation (Onycholysis)

The nail may lift away from the nail bed, starting at the tip. This creates a gap where more fungus and bacteria can accumulate.

Odor or Pain

Advanced infections may produce a mild odor and cause discomfort when wearing shoes. Pain around the nail edge can indicate secondary bacterial infection.

Treatment Options

Michigan Avenue Podiatry offers every proven treatment for nail fungus. The right approach depends on the severity of the infection, the number of nails affected, and your overall health.

Most Effective

FDA-Cleared Laser Therapy

Our laser delivers focused energy through the nail plate, heating and destroying the fungal organisms without harming surrounding tissue. No oral medications, no liver concerns, no side effects. Typically 3–4 sessions spaced 4–6 weeks apart. Clear new nail growth begins appearing at the base within 3 months.

Cosmetic Restoration

KeryFlex Nail Restoration

KeryFlex is a flexible, non-porous resin applied over the damaged nail to create a natural-looking, durable nail immediately after treatment. It allows you to leave the office with a great-looking nail while the new nail grows in underneath. Perfect before a vacation, wedding, or any event where you want healthy-looking nails now.

Prescription Topical

Prescription Antifungal Lacquers

Prescription-strength topical antifungals (such as efinaconazole and tavaborole) offer significantly better nail penetration than OTC products. Best suited for mild-to-moderate infections involving fewer nails, or as maintenance after laser therapy to prevent recurrence.

Systemic Treatment

Oral Antifungal Medications

Oral terbinafine or itraconazole work from the inside out, reaching the nail bed through the bloodstream. Highly effective for widespread or severe infections. Requires lab monitoring for liver function. We prescribe these selectively and monitor carefully throughout the course of treatment.

Why Treat Toenail Fungus Now?

Nail fungus is progressive. Delaying treatment allows the infection to deepen, spread to other nails, and complicate your overall foot health.

Frequently Asked Questions

Classic signs include nails that are yellow, brown, or white; thickened or brittle texture; a crumbly or ragged edge; distorted shape; dark debris under the nail; and a faint odor. Any nail that looks abnormal for more than a few weeks warrants a professional evaluation — other conditions like psoriasis can look similar.

Yes. Onychomycosis spreads through direct contact with infected surfaces — shared showers, locker room floors, nail salons, and contaminated footwear. Wearing sandals in public showers, never sharing nail tools, and keeping feet clean and dry all reduce your risk.

Yes. FDA-cleared laser therapy heats and destroys the fungal organisms in the nail plate without damaging surrounding tissue. Clinical studies report clear nail regrowth in the majority of patients after 3–4 sessions. Laser is preferred over oral medications for most patients because it has no systemic side effects and requires no lab monitoring.

Toenails grow about 1.5 mm per month, so visible improvement takes time regardless of treatment type. After laser therapy, patients typically see clear new nail growth beginning at the base within 3 months. Full nail replacement takes 9–12 months.

OTC topical products have very low penetration through the nail plate and limited clinical evidence for clearing established infections. They may help with very mild cases or as prevention, but for moderate-to-severe onychomycosis, prescription treatments — laser, prescription-strength topicals, or oral antifungals — are far more effective.
