A dental-based identification system for identification of individuals comprises a database configured to maintain a record of each individual registered in the system, wherein each record includes at least an identification (ID) number included in a dental-based identification tag and identification information of the individual, wherein the ID number uniquely identifies the individual； and an identification server configured to receive a radiograph of at least one tooth to which the dental-based identification tag is bonded, to detect the ID number included in the dental-based identification tag, and to search a recording associated with the detected ID number, wherein the identification server is further configured to generate and send a message upon identification of the individual.
