Doctors may use one or both of these methods after they numb the area.
Electrosurgery burns the wart with an electric charge through the tip of a needle. It's good for common warts, filiform warts, and foot warts. Your doctor could also use a laser.
Curettage is scraping off the wart with a sharp knife or small, spoon-shaped tool. Another option is excision, slicing the wart off or cutting it out with a sharp blade.
