Hemangiomas are common tumors that exhibit microscopic blood vessel proliferation. Congenital hemangiomas frequently present from birth and may become increasingly noticeable over time. Their origin is most likely developmental rather than malignant. This report describes a 6-year-old girl's gingival hemangioma and the way a sclerosing agent was used to treat it. The aim of this case report is to demonstrate the therapeutic benefits of boiled saline as a sclerotherapy for oral hemangiomas. Boiled saline is a safe and effective sclerosing therapy for oral hemangiomas. This method provided our patient with significant symptom relief at a minimal cost with few complications.
