Which dental cleaning instrument is specifically designed to remove calculus from teeth?

The scaler is specifically designed for the removal of calculus (also known as tartar) from the surfaces of teeth. Scalers have pointed tips that allow dental professionals to effectively scrape away hardened plaque and calculus that can accumulate on the tooth surfaces, particularly in the interproximal areas and along the gum line. Their design allows for the precise removal of deposits without damaging the underlying tooth structure.

Explorers are instruments used for examining surfaces of teeth to detect decay or other irregularities, but they are not primarily designed for calculus removal. Curettes are similar in function to scalers but are more curved and often used below the gum line for root planning and debridement in periodontal therapy. Probes are primarily utilized for measuring pocket depths around the teeth and assessing gum health rather than for cleaning calculus. Thus, the scaler is the most appropriate choice for this specific task.
