Etymology

The word "toothbrush" is a straightforward compound of "tooth" (from Old English tōþ, meaning "hard structure in the mouth") and "brush" (from Old French broisse, meaning "tool with bristles"). The combination reflects its functional purpose—a brush designed specifically for cleaning teeth. The term emerged in the early 17th century as dental hygiene practices became more standardized.
