Jacobus van Nierop, 51, took out healthy teeth and caused horrific injuries to the patients in the small town of Chateau-Chinon.
Van Nierop was banned from practising dentistry and fined â‚¬10,500 ($11,900).
Van Nierop fled to Canada when suspicions arose and strongly fought against 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.
Van Nierop was arrested in France in June 2013, after the number of his victims grew to 120.
However, he fled the country before his trial was due to start in December that year.
He was tracked to a small town in the Canadian province of New Brunswick and arrested under an international warrant.
The BBC's Hugh Schofield in Paris says that van Nierop was many people's worst nightmare.
Like many parts of rural France, Chateau-Chinon is badly served for medical provision, our correspondent says, adding that locals initially seemed delighted by the hard-working and smiley dentist, a larger-than-life character who witnesses said was rarely seen without his "big 4x4, a big dog and a big cigar".
But then the horror stories began. People said they had teeth ripped out for no reason - they were given heavy anaesthetic, then left with abscesses and infected gums.
A Dutchman dubbed the "dentist of horror" has been sentenced to eight years in France for mutilating the mouths of more than 100 patients.

A man has appeared in court charged with murder after the death of a man in Peterhead.

Mark Karpeles had been asked to attend a hearing in Washington on Friday.
MtGox reported in February that it may have lost nearly $500m (Â£300m) worth of the virtual currency and subsequently filed for bankruptcy protection in Japan and the US.
It later said it had "found" about a quarter of the missing sum.
A US judge ordered Mr Karpeles to travel from Japan to appear in front of the US Department of Treasury's Financial Crimes Enforcement Network to answer questions about the affair.
But a court filing by MtGox's lawyers said the France-born chief executive - who has not been charged with any crime -  would not comply.
"Mr Karpeles is now in the process of obtaining counsel to represent him with respect to the FinCen subpoena," it said.
"Until such time as counsel is retained and has an opportunity to 'get up to speed' and advise Mr Karpeles, he is not willing to travel to the US."
The lawyers also asked the court to delay Mr Karpeles' deposition until 5 May, but added that they could not guarantee he would attend on that date either.
In the meantime MtGox's site continues to tell out-of-pocket investors that a "method for filing claims will be published on this site as soon as we will be in [a] situation to announce it".
One bitcoin is currently trading for about $500, down from its high of more than $1,100 last year.
