What is one use of bite marks in forensic investigation?

Bite marks have a significant role in forensic investigations as they can provide insights into the timing of an assault and the nature of the injuries inflicted. Specifically, the characteristics of a bite mark—such as depth, shape, and the patterns of the teeth—can help forensic experts determine the time frame during which an injury occurred. This is accomplished by assessing factors like the healing process of the skin and the levels of inflammation surrounding the bite mark. For instance, fresh bite marks may show different characteristics compared to older ones that have begun to heal.

This understanding of bite mark characteristics can support criminal cases by linking a suspect to a victim, assisting in establishing a timeline of events, and corroborating testimony. Consequently, this aspect of bite marks makes them valuable for evaluating the context and circumstances surrounding a crime.
