A 40-year-old Turkish man can consider himself lucky to be alive after having a dental implant screw pushed all the way into his brain cavity by an overzealous dentist.

Ramazan Yilmaz went to a private dental clinic in his home city of Bursa, Turkey, after experiencing serious dental pain. After examining him, the dentist there informed the man that he had loose teeth and a delicate bone structure and that the best solution was to take out his natural teeth and replace them with implants. Trusting the opinion of the expert, Yilmaz agreed to the cost of the dental procedure and to have some of his teeth removed on that very same day. But things started going south from there. First, he heard the doctor, referred to only as A.D. by Turkish media, telling his assistant that the tool used to insert the implant screws into the bone wasn’t working properly, and then he had to endure the pain of having the screws inserted manually by the physician.
