Orange County health officials have ordered the closure of a children’s dental office in Anaheim after lab tests found bacteria in its new internal water system, which had replaced a system blamed for an earlier outbreak of bacterial infections.

The county Health Care Agency conducted initial testing of the Children’s Dental Group of Anaheim’s water system in September after the agency received multiple reports of children who had developed oral infections after undergoing “baby root canals” at the facility, according to the agency. The dental office is located in the 2100 block of East Lincoln Avenue.

Despite the clinic’s replacement of its on-site water system, county health officials confirmed on Thursday that multiple samples taken from the new system tested positive for Mycobacterium, which can lead to serious infections.

“This action was necessary in order to determine the actual source of the Mycobacterium since it has reappeared,” said Dr. Eric Handler, the county’s public health officer. “We are working with the Centers for Disease Control, and the Dental Board of California to determine what conditions are necessary to lift the order.”
