What causes dental calculus (tartar)?

The formation of dental calculus is the result of multiple factors acting together. 1. Personal factors such as crooked teeth and rough surfaces make it easier for food debris and bacteria to accumulate on the teeth, thereby forming dental plaque, which gradually calcifies over time to form dental calculus. 2. Unhealthy eating habits, such as excessive intake of sucrose and sticky foods, and poor oral hygiene practices, such as inadequate or infrequent brushing, can also lead to the formation of dental calculus. 3. Long-term smoking and consumption of pigmented beverages such as strong tea or coffee can easily cause pigment deposition, promoting the formation of dental calculus. Therefore, to prevent dental calculus, we should maintain good oral hygiene, clean our teeth regularly, avoid unhealthy dietary habits, and undergo regular dental check-ups.
