Extrinsic discoloration refers to the staining of the outer layer of teeth due to external factors such as food, beverages, tobacco, and poor oral hygiene. Unlike intrinsic discoloration, which is caused by internal factors, extrinsic stains can often be removed or reduced through professional dental cleaning and proper oral care habits.

Intrinsic discoloration refers to changes in the color of a tooth that originate from within the tooth structure itself, often due to factors such as developmental disturbances, systemic conditions, or certain medications. Unlike extrinsic discoloration, which affects the surface of the teeth, intrinsic discoloration is more challenging to address and may require professional dental treatments like bleaching or veneers.

Professional dental cleaning, also known as prophylaxis, is a preventive measure that removes plaque, tartar, and stains from teeth to maintain oral health and prevent periodontal disease. It typically involves scaling and polishing procedures performed by a dentist or dental hygienist, and is recommended every six months for optimal dental hygiene.
