Knocked out teeth in 2 year olds can usually be restored, but are difficult to recover on their own and require intervention through orthodontic means. For 2-year-old baby teeth knocked crooked, consider resetting the dislocated or semi-dislocated milk teeth to the normal position through manipulation, and then fixing them with wires plus composite resin, so that the milk teeth can be stabilized again. If endodontic lesions, pulp infection, or necrosis occur during this process, endodontic treatment of the baby tooth should be performed in a timely manner. The condition of the pulp and root resorption, as well as the development of the permanent tooth embryo underneath, should be reviewed regularly as prescribed by the doctor. To summarize, parents are advised to bring their babies to the doctor in time for targeted treatment. If the tooth is fixed, do not bite and chew with the tooth during the process to avoid re-injuring the tooth.
