This is the story of a 72-year-old retired electrician in Britain - let's call him "Jack" - who forgot to tell his surgeon that he wore dentures before his surgery. 

Six days after having a benign lump removed from his belly while under general anaesthesia, Jack turned up at the emergency room. 

He complained of blood in the mouth, difficulty swallowing, and pain so intense that he couldn't eat solid food.

A fiber optic camera on the end of a tube was inserted through a nostril and revealed a large, semicircular object covering his vocal cords.

 "On explaining this to the patient, he revealed that his dentures had been lost during his general surgery eight days earlier, and consisted of a metallic roof plate and three front teeth," Harriet Cunniffe, an ear, nose and throat surgeon at Universities Hospitals in Yarmouth noted. The denture was removed surgically, and Jack was discharged six days later. But had to return several more times for further treatment.
