A dentist who tricked patients into getting expensive and unnecessary dental work has been banned from practice by UK’s General Dental Council.

Dr. Constantine Saridakis had previously paid a hefty amount for unneeded dental fillings performed before 2007. He was suspended from treating NHS patients in 2008, but did anyway, altering patient records to cover it up.

‘The committee considered suspension of your registration,” said the chair at Dr. Saridakis’s hearing, “but concluded that a period of suspension would not sufficiently protect the public in future.”

In multiple cases, the doctor recommended multiple fillings (as many as 10) on patients whose charts did not indicate any tooth decay. His partner provided a second opinion on some cases, often finding no evidence of decay.

When confronted by his partner, Dr. Saridakis allegedly replied, “Sometimes I’m preventative, and sometimes I’m in a money-making mood.”
