A mechanical polish is effective at removing which type of deposits?

A mechanical polish is particularly effective at removing extrinsic stains and soft deposits that accumulate on the tooth surface. Extrinsic stains are those that occur on the exterior of the teeth, often caused by substances like coffee, tea, tobacco, and certain foods. Mechanical polishing techniques, which may involve specialized dental pastes or polishing devices, help to abrade these stains, resulting in a smoother and more aesthetically pleasing surface.

Soft deposits, including plaque, can also be effectively removed during mechanical polishing. This process not only enhances the cosmetic appearance of the teeth but also contributes to oral hygiene by eliminating areas where bacteria can thrive. The removal of these soft deposits is crucial for preventing the development of dental caries and periodontal diseases.

Intrinsic stains, on the other hand, are typically associated with discoloration from within the tooth structure, such as those resulting from certain medications or developmental conditions. These stains do not respond well to mechanical polishing as they are not located on the surface. Therefore, the mechanical polish is not effective in removing intrinsic stains, which differentiates it from works on extrinsic types.

While plaque may be removed to some extent, the emphasis is on the broader category of extrinsic stains and soft deposits, making this option comprehensive and correct.
