What does the term "tartar" refer to in dental terms?

The term "tartar" in dental terms refers specifically to calculus, which is a hardened form of dental plaque that develops when plaque is not removed from the teeth and subsequently mineralizes. Tartar can accumulate on the teeth and contribute to various dental issues, such as gum disease and cavities, as it creates a rough surface that can attract more plaque. Proper dental hygiene, including regular brushing and professional cleanings, is essential to prevent the buildup of tartar.

In contrast, dental plaque is a soft, sticky film of bacteria that forms on teeth, while enamel is the hard, outer surface of a tooth that protects it from decay. Dentin, on the other hand, is the layer beneath the enamel that provides support and structure to the tooth. Understanding these distinctions is important for maintaining oral health and comprehending the preventive measures needed in dentistry.
