A northwestern Pennsylvania man must stand trial on charges that he assaulted his dentist with a tire iron because the doctor prescribed antibiotics instead of pulling a tooth.

The Erie Times-News (http://bit.ly/1fOAO7K ) reports 29-year-old Philip Kienholz waived his preliminary hearing Thursday on charges including aggravated assault stemming from the Dec. 20 incident.

Erie police say Kienholz was angry at the dentist, cornered him in a room with another patient and hit the dentist in the wrist with the tire iron. Police say Kienholz then ran away.

Kienholz is in the county jail unable to post $25,000 bond. His Erie County public defender did not immediately return a call seeking comment Friday.
