The objective of this study was to determine the prevalence in the prevention of premature loss of primary teeth in children at the "Unidad Educativa Ibarra" in Ecuador. A non-experimental cross-sectional study was conducted with a sample of 123 third-grade children, using structured surveys to identify associated risk factors. The results indicated that cavities, trauma, and inadequate oral hygiene are the main causes of premature loss of primary teeth. It was observed that 82% of the children brush their teeth three times a day, while 51% regularly visit the dentist. The proposed strategies include education on oral hygiene, promotion of a healthy diet, and implementation of preventive school programs. These findings highlight the importance of prevention and continuous monitoring to ensure children's dental health and the proper development of permanent dentition
