This burglar clearly doesn’t fear the dentist’s office.

A crook broke into a Queens dental office and stole a laptop and syringes, cops said.

The thief, caught in this surveillance video, climbed into an unlocked window of Steinway Family Dental in Astoria on Steinway Street, near 34th Avenue, about 3:50 a.m. Friday, according to NYPD spokesman Lt. John Grimpel.

Police said the suspect wore dark jeans, white sneakers, and a light-colored jacket that reads “USA 928” on the back during the heist.
