When you come to Dallas Podiatry Works for a fungal nail appointment, your doctor will go over the diagnosis with you and discuss your treatment. For your toes to recover, the nail fungus needs to be eradicated. An important part of that is removing as much of the infected tissue as possible. During the appointment, the medical technician will do this carefully with a power burr. The procedure is done in the treatment room and is generally pain free. Often it takes two to four treatments to eliminate the problem.
