What calculus is

Soft plaque that is not cleaned away within roughly 24-72 hours absorbs minerals from saliva and hardens into calculus. Once hardened, neither a toothbrush nor floss can remove it.

Why it has to be removed

The rough calculus surface holds bacteria against the gum line and sustains inflammation. In patients with risk factors, prolonged gingivitis can progress to periodontitis and alveolar bone loss - damage that does not reverse on its own.

Signs to get checked

  • Bleeding when brushing or flossing.
  • Persistent bad breath despite regular hygiene.
  • Visible hard yellow or brown deposits at the tooth neck.
  • Swollen red gums, or sensitivity to cold food.

How often

Roughly every six months is a common reference point, but smokers, orthodontic patients and those with periodontal disease usually need shorter intervals. The actual interval is set by your clinician after assessment.
