Which instrument is used to remove decay from a tooth?

The excavator is specifically designed for the removal of decay from a tooth. This instrument typically features a curved or spoon-shaped working end, which allows dental professionals to scoop out decayed tooth material effectively. Its design facilitates access to various areas within the tooth structure, enabling a thorough cleaning of the cavity and preparation of the tooth for further restorative procedures.

In contrast, a scaler is primarily used for the removal of plaque and calculus from the tooth surface, especially in periodontal treatments. A dental explorer serves to detect decay and irregularities in the tooth enamel but is not designed for removing decay itself. The periodontal probe is utilized to measure the depth of periodontal pockets and assess gum health, rather than for any direct purpose related to decay removal. Each of these instruments has its specific function, but the excavator is uniquely suited for the task of decay removal within a tooth structure.
