Dental trauma in deciduous dentition is an emergency, so it is necessary to know how to approach the child and how to heal the injury. Injuries to deciduous teeth occur between the ages of one and a half and three due to insufficiently developed motor skills, with the upper front teeth being the most frequently affected. Due to the lower density and mineralization of the bone tissue, injuries to the supporting tissue of the teeth predominate in childhood. When a child arrives with a dental trauma, a detailed medical history must be taken and a clinical examination carried out. A clinical examination using the knee-to-knee method is recommended, first an extraoral and then an intraoral examination. If necessary, an X-ray imaging is performed. Treatment choice depends on the type of injury, the age, and the child's cooperation. The aim is to preserve the deciduous tooth, as its loss can cause numerous complications. However, sometimes deciduous tooth extraction is the treatment of choice. It is critical to know the possible consequences of premature deciduous tooth loss and the prevention methods.
