Injuries to children are a major threat to their health, and they are generally a neglected public health problem. For children, aged 0-6 years, oral injuries account for 18% of all physical injuries and the mouth is the second most common area of the body to be injured.They most commonly occur between 2 and 6 years of age with injuries to periodontal tissues occurring most frequently. Children with these injuries present to many healthcare settings, including general dental practitioners, emergency medical services, pharmacists, community dental clinics, and specialist dental services. Consequently, each service provider needs to have the appropriate knowledge, skills, and training in how to care for children with TDIs to their primary dentition. The primary teeth Guidelines contain recommendations for the diagnosis and management of traumatic injuries to the primary dentition, assuming the child is medically healthy with a sound and caries-free primary dentition. Management strategies may change where multiple teeth are injured.
