Hardened dental plaque, also known as tartar or calculus, is a deposit that forms on teeth. It is created when plaque, a sticky film of bacteria, combines with minerals in saliva, primarily calcium. This process leads to a tenacious, rough coating that can be unsightly and detrimental to oral health.
Addressing this calcified deposit is crucial for maintaining healthy gums and preventing tooth decay. Its removal can improve the appearance of teeth, reduce the risk of gingivitis and periodontitis, and contribute to overall oral hygiene. Historically, various methods, from rudimentary scaling tools to modern ultrasonic devices, have been employed to combat its accumulation.
