How can detectives identify a person by there teeth if the person had cosmentic dental work done?

Detectives can identify a person by their teeth even after cosmetic dental work by comparing dental records, which include unique characteristics such as tooth size, shape, alignment, and any existing dental implants or restorations. Dental professionals often document specific details of a person's dental history, including X-rays, which can reveal distinctive features. Additionally, forensic odontologists can analyze bite marks or dental patterns, which remain consistent despite cosmetic alterations. Ultimately, these factors can help establish a definitive link to an individual's identity.
