Toenail fungus is a fungal infection beneath the nail that causes the nail to yellow and thicken.

This infection might spread to other toenails if left untreated. While most over-the-counter treatments for foot fungus offer limited relief or require multiple applications over weeks or months to eradicate the infection, toenail fungus laser treatment can be completed in as little as one session and has a track record of successfully treating this unsightly condition
