No data exists to quantify how many US criminal cases have included bite mark evidence. But Golden estimates that such evidence has been correctly used to convict offenders “in nearly 1,000 cases,” and says that forensic odontologists offer up accurate analysis about 98 percent of the time.
Is Forensic Odontology reliable?
Although bite mark evidence has been used across the country in many criminal prosecutions, there is no real scientific support or research into the accuracy or reliability of bite mark evidence.
How accurate is bite mark evidence?
Though the science behind bite marks has been debunked, it continues to be used in courts. And when presented as scientific evidence by so-called experts in court, bite marks seem to offer jurors a false sense of certainty.
What is the error rate of identification with dental patterns?
The American Board of Forensic Odontology and the Innocence Project have estimated error rates for incorrect identification based on dental records. The estimated ranges of these error rates are: 63-91 percent.
Is Forensic Odontology still used?
However, the American Board of Forensic Odontology still stands behind the technique. Bite mark forensics are not only used for identifying perpetrators, they testified, but is also useful in child abuse cases to prove that bite marks belong to adult members of a household as opposed to other children.

Why are teeth used to identify unknown remains?
The principal basis of the dental identification lies in the fact that no two oral cavities are alike and the teeth are unique to an individual. The dental evidence of the deceased recovered from the scene of crime/occurrence is compared with the ante-mortem records for identification.
What things about someone’s teeth may be very obvious to someone looking at a bite mark?
A clear impression means that there was significant pressure; an obvious bite signifies medium pressure; and a noticeable impression means that the biter used violent pressure to bite down. A forensic dentist can tell a lot about the teeth of the biter based on the bite mark.
What are the 7 types of bite marks?

What difficulties would a forensic investigator face when trying to identify thousands of remains?
What difficulties would a forensic investigator face when trying to identify thousands of remains? They could have similar characteristics such as the same teeth, DNA, or admissible dental evidence to the point where it could get difficult to find out the actual identity.
What problems does forensic odontology face?
There is insufficient study that the techniques used can correctly identify specific or unique source, meaning that the marks left (the unknown) can be traced and attributed uniquely to one specific source. A person’s dental profile changes over time. Frequently there is unequal application of force in the real world.
Why must a forensic dentist be called immediately if a bite mark is suspected?
The forensic dentist must be called right away because bite marks change over time. To make sure that the mark is human, the forensic dentist can look at the bite mark pattern, because animals leave a different bite pattern than humans.
What two tasks do forensic odontologists have?
Forensic dentists (also known as forensic odontologists) have two different tasks: to identify the dead by their teeth and to determine who (or what) did the biting when bite marks are found.
