How long does it take for plaque to mineralize into calculus?

Plaque typically begins to mineralize into calculus, commonly referred to as tartar, within approximately 24 to 72 hours after its formation. The process of mineralization involves the deposition of calcium and phosphate ions in the plaque biofilm, which can lead to the development of hard deposits that adhere to the tooth surface.

Understanding that mineralization can occur swiftly emphasizes the importance of maintaining good oral hygiene practices, as plaque can begin to harden and become less manageable if not removed in a timely manner. Regular brushing and flossing help to disrupt this process before significant mineralization occurs, reducing the potential for calculus formation.
