Quizplus · Accepted Answer

Extrinsic stains are caused by external sources such as food or drink, tobacco use, or poor oral hygiene. These types of stains can usually be removed or improved with professional cleaning or at-home whitening products. Natural stains, such as those caused by aging or certain medications, are intrinsic and cannot be removed as easily. Infected stains may refer to discoloration caused by a dental infection or decay, but this term is not commonly used in dentistry.
