'Dentist of horror' Jacobus van Nierop jailed in France
Jacobus van Nierop, 51, "took pleasure" in causing horrific injuries to patients in the small central town of Chateau-Chinon, prosecutors said.
He was banned from practising dentistry and fined €10,500 (£8,140; $11,900).
Van Nierop fled to Canada when suspicions arose and strongly fought extradition to France in 2014.
The court in the central French town of Nevers heard that patients had suffered broken jaws, recurrent abscesses and septicaemia from van Nierop's work. He had drugged patients then mutilated them as they slept in his dentist's chair.
Prosecutor Lucile Jaillon-Bru said van Nierop had carried out "useless and painful procedures".
She said his aim had been to earn money through claiming on patients' medical insurance schemes and to take "pleasure at causing pain".
Reports from inside the courtroom on Tuesday said that van Nierop had admitted responsibility, saying he "wasn't interested in people" and could not remember his patients.
One 65-year-old victim said van Nierop had pulled out eight of her teeth in one sitting, telling judges she was "gushing blood for three days... and had no teeth for a year and a half".
