A tragic incident unfolded in Illinois this summer when a 17-year-old girl lost her life following complications from a dental procedure, as confirmed by a medical examiner.

Sophie Farmer passed away in a hospital on July 24, just days after becoming unresponsive during a dental surgery on July 21. The procedure took place at Northern Lakes Oral Surgery and Dental Implant Center located in Grayslake, Illinois, according to reports from the Northwest Herald and the Lake & McHenry County Scanner.

The Cook County Medical Examiner’s Office classified her death as “natural,” attributing it to “complications of dental extraction surgery under sedation.” They further noted that these complications were linked to an ARID1B gene mutation and several neurological abnormalities.
