What does flosser mean?
A flosser is, most simply, a person who flosses — someone who cleans between their teeth with dental floss as part of their oral hygiene routine. The label is informal and often carries a quietly virtuous connotation: being described as a 'daily flosser' implies diligence and good habits, something dentists encourage and patients often claim. In recent years the noun has also come to denote cleaning devices themselves, particularly water flossers (oral irrigators) that use a pressurised stream instead of thread, so the word now names both the doer and, loosely, the tool. A third, lighter sense emerged after 2017, when the 'floss' dance move became a global craze: a flosser can be someone swinging their arms and hips in that distinctive pattern. The word derives from floss, the silky thread at the heart of dental care, and its everyday usefulness lies in turning a routine habit into an identity — the sort of small badge of self-care people mention proudly at the dentist's chair.
nounA person who flosses their teeth; more broadly, an agent or device that cleans between the teeth with dental floss. The term can also denote someone performing the popular 'floss' dance move.
- A person who uses dental floss to clean between their teeth.
- A device that cleans between the teeth, especially a water flosser or oral irrigator.
- A person who performs the 'floss' dance move.
"As a diligent flosser, she never skipped her nightly routine even while travelling."
"Dentists can usually tell within seconds which of their patients are genuine daily flossers."
"He swapped string for a water flosser after his hygienist recommended it for his braces."
Regular English plural; used both for people and for multiple devices.
"The clinic hands out starter kits to first-time flossers."
The word 'flosser' now pulls double duty: your dentist means the person who flosses their teeth, but since 2017 it might just mean someone busting out the floss dance on the internet.

Etymology of flosser
The word traces back to 'floss', a term borrowed in the nineteenth century from French-influenced silk terminology, where 'floss' or 'floss silk' denoted soft, untwisted silk filaments. Dental floss was originally made from just such silk thread, which is how the material's name transferred to oral hygiene. An agent noun formed from the verb 'to floss', 'flosser' follows the ordinary English pattern of adding '-er' to a verb to name the person performing the action, and its device sense arose when manufacturers applied the same branding to irrigating appliances.

How flosser is actually used
The word is informal and conversational rather than technical; dental professionals tend to speak of 'patients who floss' in formal contexts but happily use 'flosser' in everyday advice. Since the late 2010s the noun has also been applied to devices ('water flosser'), and the rise of the floss dance gave the word a playful secondary sense among younger speakers.
