Length of healing time for burn wounds to heal depends on the depth and extent of the wound. First-degree burns heal quite quickly in usually less than 3 weeks. Deep second-degree and third-degree burns may require debridement, antibiotic dressing changes, and surgical reconstruction with skin grafts or flaps requiring months of healing and rehabilitation. Larger 2nd and 3rd degree burns over 90% of total body surface area may be fatal if not aggressively treated soon after the incident.
