What is calculus in the context of dental hygiene?

In the context of dental hygiene, calculus refers to hardened plaque that adheres to tooth surfaces. Plaque is a soft, sticky film of bacteria that forms on teeth and can lead to dental issues, such as cavities and gum disease, if not removed regularly through brushing and flossing. When plaque is not removed, it can mineralize and harden over time due to the minerals present in saliva, forming calculus, also known as tartar.

Calculus provides a rough surface that attracts more plaque, making it even more challenging to maintain oral health. Its presence can contribute to periodontal disease, as it can irritate the gums and create pockets where bacteria can thrive. Removal of calculus typically requires professional cleaning by a dental hygienist or dentist, as it cannot be eliminated through routine oral hygiene practices at home. Understanding this concept is vital for dental hygienists, as it underlines the importance of regular dental visits and proper oral hygiene practices to prevent the formation of calculus and maintain overall oral health.
