Toenail Fungus: Why It Won't Go Away on Its Own

How nails become infected

Fungal organisms thrive in warm, damp environments: sweaty shoes, gym showers, pool decks. They enter through tiny separations between the nail and nail bed, then feed on the keratin in the nail itself. Because the fungus lives under and inside the nail plate, creams that work on athlete's foot usually can't reach it.

Left untreated, the infection spreads deeper and to other nails. The nail thickens, yellows, and can become painful in shoes. It can also serve as a reservoir that keeps reinfecting the surrounding skin.

Treatment options

Oral antifungal medications can be effective but require months of treatment and periodic liver monitoring, which makes them unsuitable for some patients.

Our office offers 808 nm pulsed cold laser treatment, a painless, in-office procedure that targets the fungus through the nail without drugs or downtime. Combined with proper nail care and prevention habits, laser treatment lets healthy nail grow in as the damaged nail grows out.

Keeping nails clear

Rotate your shoes so each pair dries fully, wear moisture-wicking socks, use shower shoes in shared wet areas, and disinfect home nail tools. Because regrowth takes months, early treatment means less time hiding your toes. Call (718) 232-2100 to have your nails evaluated.
