How soon can plaque start to harden into calculus?

Plaque can begin to mineralize and harden into calculus, also known as tartar, within a timeframe of about 24 hours after it forms on the teeth. This mineralization process occurs because plaque, which is a soft and sticky biofilm of bacteria, starts to accumulate minerals from saliva, leading to the calcification and development of calculus.

Understanding this timeline is important for dental health, as it underscores the necessity of regular oral hygiene practices such as brushing and flossing. If plaque is not removed within this period, it can lead to calculus buildup, which can contribute to periodontal disease and other oral health issues.

Being aware of the rate at which plaque hardens into calculus reinforces the critical nature of maintaining good dental hygiene routines to prevent the progression of oral health problems.
