Official App of the International Association of Dental Traumatology (IADT) Detailed Description: The official IADT App, ToothSOS, provides information for both Patients and Professionals in the event of traumatic tooth injury. For Patients, the App provides easy to understand emergency steps to take in all dental injuries. The immediate care provided at the site of injury will determine the survival of the injured tooth and the smile of your child. This App should be in every mobile device of everyone around the world. In order to save more teeth and smiles, it’s important you share this App with as many people you can. Start with friends, relatives, teachers and coaches. For Professionals, quick access to the Dental Trauma Guidelines provide detailed information caring for patients with dental injuries. They represent the current evidence based on literature research and professional opinion, as well as additional information about the IADT and resources for continuing education. As is true for all guidelines, the health care provider must apply clinical judgment dictated by the conditions present in the given traumatic situation. The IADT does not guarantee favorable outcomes from following the Guidelines, but using the recommended procedures can maximize the chances of success.
