What is the primary use of a high-speed handpiece in dentistry?

The primary use of a high-speed handpiece in dentistry is to cut a cavity or crown preparation. This instrument operates at high RPMs (revolutions per minute), allowing dentists to efficiently and precisely remove decay from a tooth or prepare a tooth for a crown. The design and speed of the high-speed handpiece enable it to cut through enamel and dentin with minimal pressure, making it ideal for intricate restorative procedures. Its ability to work quickly and effectively minimizes the time the patient spends in the chair and can contribute to better overall outcomes in restorative dentistry.

While other instruments serve different functions, they do not match the high-speed handpiece's capabilities for preparing teeth for restoration. Polishing teeth, extracting teeth, and placing dental sealants are typically done using different types of handpieces or instruments that have specialized uses suited to those specific tasks.
