What does “Dental calculus” mean?
Dental calculus, or tartar, is a hard deposit formed when plaque mineralizes and adheres to tooth or prosthesis surfaces. It can occur above or below the gumline and requires professional removal.
Why is it removed?
Rough deposits make it easier for plaque to remain and harder to clean. Their distribution and amount are assessed together with gum inflammation.
Can I scrape it off at home?
Scraping it yourself with a sharp tool can injure teeth, prostheses, or gums. Removal should be performed with professional instruments and adequate visibility.
How is recurring buildup managed?
Maintain brushing and interdental cleaning to prevent plaque buildup. Checkup and removal plans consider individual differences in deposits and inflammation.
