What does dentifrice mean?
A dentifrice is any preparation — most commonly a paste, but also a powder or gel — applied with a toothbrush to clean the teeth. The word comes from the Latin dens ("tooth") and fricare ("to rub"), so it literally means "tooth-rubbing" substance. While ordinary speakers simply say toothpaste, dentifrice remains standard vocabulary in dentistry, pharmacology, and product labeling, where it usefully covers powders and gels as well as pastes. Modern dentifrices typically contain mild abrasives, fluoride for cavity prevention, flavoring agents, and humectants that keep the paste from drying out. The term carries a formal, slightly clinical tone, appearing in scientific papers, regulatory documents, and period advertisements more often than in casual conversation. Knowing it adds precision when writing about oral care, and its transparent Latin roots make its meaning easy to remember once encountered.

Etymology of dentifrice
Dentifrice derives from the Latin dentifricium, formed from dens, dentis ("tooth") and fricare ("to rub"), entering English via French in the early modern period. It shares its first element with words such as dental, dentist, and denture, all traceable to the same Latin root. The second element connects it etymologically to friction and friable, which also descend from fricare.
How dentifrice is actually used
