Richard Harris was given a 12-week jail term suspended for 12 months at Dudley Magistrates Court on Thursday after admitting one count of burglary.
The 44-year-old stole dental-related items from Bhandal Dental Practice after entering the firm's building in Dudley High Street on June 3 last year.
Harris, of Moseley Road, Birmingham, was given the suspended sentence, with the court reasoning: "The offence is so serious that only a custodial sentence can be justified. The reasons for this: because the defendant has a flagrant disregard for people and their property."
The court also ordered him to pay £100 compensation.
