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.

The tooth structure is composed of multiple layers, each serving a specific function to protect and support the tooth's integrity. These layers include enamel, dentin, pulp, and cementum, working together to facilitate chewing, protect against decay, and support overall oral health.

Systemic conditions refer to diseases or disorders that affect multiple organs or the entire body rather than a single part. They often involve complex interactions between genetic, environmental, and lifestyle factors, necessitating a holistic approach to diagnosis and management.

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.

Bleaching is a process that removes or alters the color of a material, often used in textile and paper industries, and also refers to the loss of symbiotic algae in coral reefs due to environmental stressors like temperature changes. The latter form of bleaching is a significant environmental concern as it affects marine biodiversity and ecosystem health.

Veneers are thin, custom-made shells designed to cover the front surface of teeth to improve their appearance, often used for cosmetic corrections such as whitening, reshaping, or closing gaps. They are typically made from porcelain or resin composite materials, providing a natural tooth appearance and durability.
