よくある間違い：
Learners sometimes confuse “plaque” with “plague.” “Plaque” (with /æk/ sound) is a film on teeth, while “plague” (with /eɪg/ sound) is a serious disease. Another mistake is using “stone” or “hard dirt” instead of the correct word “plaque” or “tartar.”

類義語
deposit (General term for material that has built up somewhere; not limited to medical contexts.)
