Which dental tool is primarily used to remove caries?

The tool primarily used to remove caries is the excavator. An excavator is specifically designed with a spoon-shaped end that allows dental professionals to efficiently scoop out decayed tissue from the cavity. Its design and sharp edges enable it to cleanly remove soft, infected dentin surrounding the carious lesion while preserving healthy tooth structure as much as possible. This precision is essential in restorative dentistry, ensuring the area is adequately prepared for filling materials.

Other tools serve different functions: an explorer is used to examine the surface of teeth for decay, calculus, or other issues but is not meant for removal. A scaler is used to remove plaque and tartar from the surfaces of teeth, typically above the gum line, rather than for treating cavities. A mirror aids in visibility during procedures but does not play a role in the removal of caries itself. Therefore, the excavator stands out as the appropriate choice for the specific task of caries removal.
