What is the function of a high-speed handpiece?

The high-speed handpiece is primarily designed for cutting and removing decay quickly during dental procedures. Its high rotational speed allows for efficient and precise removal of hard tissue, such as enamel and dentin, making it an essential tool in restorative dentistry. This functionality is crucial for preparing cavities for fillings and shaping teeth for various procedures.

Unlike other options, such as polishing teeth or applying fluoride treatments, which involve slower and often hand-held instruments for more delicate tasks, the high-speed handpiece's primary purpose revolves around its ability to perform rapid and effective preparation work in the dental workflow. It is also distinct from tools used for administering anesthetics, as those tools serve an entirely separate function related to patient comfort and pain management.
