Quizplus · Accepted Answer

Intrinsic stains are caused by internal factors such as trauma, medications, or developmental defects and cannot be removed by typical dental cleaning procedures. Extrinsic stains, on the other hand, are caused by external factors such as food, drink, and tobacco and can often be removed by good oral hygiene practices and professional cleanings. Natural stains refer to normal variations in tooth color, while infected stains are not a recognized dental term.
