What is the term for the hard, calcium-like deposit that forms on the teeth?

The term for the hard, calcium-like deposit that forms on the teeth is calculus. This formation occurs when plaque, a sticky film of bacteria, is not adequately removed from the teeth through regular brushing and flossing. Over time, the minerals from saliva combine with the plaque, leading to the hardening process that creates calculus, commonly referred to as tartar.

Calculus can cause various dental issues, including gum disease, as it is rough and can attract more plaque and bacteria. Proper oral hygiene is crucial for preventing the buildup of plaque and, subsequently, calculus. Regular professional cleanings by a dentist or dental hygienist are also essential for removing calculus that has hardened, as it cannot be removed by brushing alone. This accumulation can significantly impact oral health, making it a critical aspect of dental care.
