Toenails get infected as a result of mechanical trauma to the nails creating an entry point for fungal spores. Once infected, toenails will remain infected unless they are treated. Infection can cause discolouration, hardening, thickening, disfigurement of the nails and even pain. Fungal nail infections are very common and affect 1 in 15 people in the UK. The laser procedure is fast, effective and comfortable with results seen within weeks as the nail plate grows out clear. Laser works by killing the fungus that destroys the nail.
