How often should I really visit the dentist?

Every 6–12 months for most adults, adjusted by risk — more often with gum disease, smoking, diabetes, or a history of frequent decay. Cleaning removes calculus that brushing cannot.

Calculus hardens within days and cannot be removed by brushing. Cleaning prevents gum disease rather than treating existing symptoms.

Risk-based intervals are reasonable: 12 months for low-risk adults with excellent hygiene, 3-6 months for smokers, diabetics or those with gum disease.
