What are examples of soft deposits in dentistry?

Soft deposits in dentistry refer to the materials that can be found on the tooth surfaces that have not yet undergone calcification. Plaque, which is a soft, sticky film of bacteria that forms on teeth, and food debris are prime examples. These substances can lead to dental issues like cavities and gum disease if not adequately removed through proper oral hygiene practices.

In contrast, substances like calculus, commonly referred to as tartar, represent hardened deposits that have formed from the mineralization of plaque and food debris. Amalgam and composite refer to dental materials used in fillings and do not fall into the category of deposits on teeth. Similarly, enamel and dentin are hard, calcified tissues that make up the structure of teeth, and they are not classified as soft deposits. Thus, plaque and food debris fit the definition of soft deposits quite well.
