According to the study published in the journal Nature Reviews Neurology, it was revealed that teeth scanning can reveal your lifetime exposure to toxins and metals linked to brain diseases like Parkinson's and Alzheimer's.

The study was performed by American and Australian scientists. Manish Arora, an Indian-origin scientist who is associated with Mount Sinai and Icahn School of Medicine in New York, along with Dominic Hare who is associated with the University of Technology, Sydney utilized a dental biomarker technology to differentiate between breast-fed babies and formula-fed babies.

The researchers stated that this technology is applied to study the link between early iron exposure and late-life brain diseases like Parkinson's and Alzheimer's, which are associated with the abnormal processing of iron.

"Our analysis of iron deposits in teeth as a method for retrospective determination of exposure is just one application: we believe teeth have the potential to help track the impact of pollution on health globally," Arora said.
