Beware a scorned woman with dental pliers. A Polish man learned this lesson the hard way when his dentist ex-girlfriend pulled out all his teeth during a surgery days after he'd dumped her for another woman.

"I tried to be professional and detach myself from my emotions," said Anna Machowiak, 34, who practices her trade in Wroclaw, Poland, according to the U.K.'s Daily Mail. "But when I saw him lying there, I just thought, 'What a bastard.'"

Machowiak then allegedly gave ex-boyfriend Marek Olszewski, 45, a large dose of anesthetic and yanked all his teeth out. She wrapped his head in a bandage to keep him from speaking when he came to and told him there had been some complications.

"I knew something was wrong because when I woke up I couldn't feel any teeth and my jaw was strapped up with bandages," Olszewski told the Daily Mail. "She told me my mouth was numb, and I wouldn't be able to feel anything for a while and that the bandage was there to protect the gums, but that I would need to see a specialist."

"I didn't have any reason to doubt her, I mean, I thought she was a professional," he said. "But when I got home, I looked in the mirror and couldn't f***king believe it. The b**ch had emptied my mouth."

Mackowiak is under investigation for medical malpractice and abusing the trust of a patient. She could face up to three years in prison. And Olszewski's new girlfriend has dumped him because he no longer has any teeth.
