The patient in Radomsko was undergoing preparations for the crown when he became suspicious the dentist was drunk, Polskie Radio reported Wednesday.
The dentist polished the patient's front teeth, and then gave him five jabs of anesthetic, Polskie Radio reported.
"After a few minutes, the 28-year-old saw that his front tooth had landed in the bin, and at that moment he decided to protest," police spokesperson Aneta Komorowska said.
The patient demanded his dental records, but the dentist, 50, banished the patient from the surgery room, Polskie Radio reported.
When police were finally able to enter the dentist's office, they confirmed he was under the influence of alcohol, and blood tests have been taken to determine how drunk he was during the dental procedure, the radio station reported.
Charges will be brought when medical experts determine the extent of the alleged damage to the patient, the radio station said.
