When a wart isn't cured through home remedies, a dermatologist is able to treat and remove any warts. A dermatologist uses a number of different practices to treat the wart, including cantharidin, cryotherapy, electrosurgery, and curettage or excision.
Many warts go away with time, and not all warts need to be treated with the help of a doctor. To have a wart removed, a dermatologist sometimes uses cantharidin, which is a substance to paint over the wart. Cryotherapy is another treatment option, which freezes the wart. Electrosurgery and curettage, which burn off the wart, and excision, which cuts off the wart, are also treatment options.
