Which term is not appropriate for referring to a patient who is no longer in the dental practice?

The term "old patient" is often viewed as inappropriate in a professional healthcare setting, including dental practices. This language can imply a negative connotation or lack of respect towards the patient and may suggest that the patient is outdated or no longer valuable, which is not the case.

In contrast, using terms like "former patient," "previous patient," and "past patient" maintains a level of professionalism and respect. These terms are commonly accepted in healthcare contexts as they neutrally convey the idea that the patient is no longer receiving care from the practice, without implying any negative judgment. This respectful language is important for maintaining positive relationships and a good reputation within the community.
