Coldwater Orthodontics

Coldwater Orthodontics, also known as Coldwater Ortho, is an orthodontic practice headquartered in the United States, with its primary office located in Michigan. The organisation provides orthodontic care to patients, focusing on the diagnosis, prevention, and correction of dental and facial irregularities. Services typically include the fitting of braces, clear aligners, and other corrective appliances aimed at improving oral function and aesthetics. As a private dental specialty provider, it serves the local community and surrounding areas in Michigan. The practice operates under the aliases Coldwater Orthodontics and Coldwater Ortho in its public communications and billing documents.

In November 2020, Coldwater Orthodontics was identified as a victim of a ransomware attack carried out by the Egregor threat group, which subsequently posted the practice's name on its data leak site. According to the leak site notification, the attackers exfiltrated a set of files that primarily consisted of business forms and marketing materials used by the office. The initial data dump did not appear to contain identifiable patient health information, though investigators could not rule out the possibility that protected health data was accessed or stolen during the incident. The event highlighted the broader trend of ransomware groups targeting healthcare and dental organisations despite concerns about disrupting essential medical services. No further details regarding the practice's size, ownership structure, or subsequent remediation efforts have been disclosed in publicly available sources.
