Morphology
The meaning 'a powdered substance used to clean teeth' is directly and compositionally derived from combining 'tooth' (relating to teeth) with 'powder' (a fine dry substance). This noun+noun compounding is a transparent, productive pattern in English (and parallels exist in many other languages), so a B1 learner who knows both constituents can readily infer the meaning.
Etymology
Tooth powder comes from the simple idea of a fine powder used on the tooth. People long ago rubbed dry powders on their teeth to clean them, so the name literally means 'powder for teeth' and today it refers to a powdered cleaner used instead of toothpaste.
