The steps to deal with a bumped off toenail include clearing the wound, bandaging it, and preventing infection. First of all, clean up the necrotic tissue and dirt in the nail bed, use hydrogen peroxide solution and water to clean the wound, and then use alcohol and povidone-iodine medicine to disinfect the wound. After the wound is cleaned, use sterile, breathable gauze to bandage the nail bed wound. It will take about 1-2 months for the toenail to grow back, so during this period, you should pay attention to not letting the wound touch water, keep the wound dry and clean, and pay attention to a light diet to prevent the wound from getting infected. Although the toenail will grow again, it is still recommended to pay attention to safety in life, if the wound is serious, go to the hospital in time to avoid the deterioration of the wound.
