A man gardening in his backyard unearthed an urn filled with human ashes and false teeth this week in Queens, cops said. 

The 33-year-old made the spine-chilling discovery outside of his home near 20th Road and 150th Street in Whitestone just before 8:30 p.m. Thursday, and immediately called 911, a police source told The Post. 

The Medical Examiner’s Office determined the unidentified remains were from a human cremation, and bone fragments were left behind, cops said. 

The investigation is ongoing. 

Permission from the property owner along with government permits are required in order to bury human remains on private property in New York City.
