Other forms: flossing
Floss is the thin thread pulled between teeth to clean the gaps. Dental floss, use floss, floss every night.
A toothbrush reaches about three of the five surfaces of a tooth, which is the whole argument for flossing, and interdental brushes do the job better for most people. As a verb, to floss is to use it. Note candyfloss, which is the British name for spun sugar; and that the Floss dance was a global phenomenon around 2018 and is unrelated to teeth in every respect.
