What is a notable characteristic of extrinsic stains compared to intrinsic stains?

Extrinsic stains are characterized by their ability to be removed through mechanical methods, such as coronal polishing. These types of stains are located on the external surface of the teeth and are primarily caused by external factors, including consumption of certain foods and beverages, tobacco use, and poor oral hygiene. Because they do not penetrate the tooth structure, they can be effectively eliminated through professional cleaning techniques.

In contrast, intrinsic stains arise from internal factors, such as genetic conditions, dental trauma, or certain medications taken during tooth development. These stains penetrate the enamel and the underlying dentin, making them more challenging to remove without more invasive procedures, such as tooth whitening or restorative treatments.

By understanding that extrinsic stains can be effectively managed through routine dental procedures like coronal polishing, dental professionals can provide better patient care focused on oral hygiene and aesthetic outcomes.
