Which hand piece operates at 30,000 rpm and is used to polish the tooth?

The slow speed hand piece, which operates at approximately 30,000 revolutions per minute (rpm), is commonly used for polishing teeth. This hand piece allows for better control and precision when performing procedures such as polishing, since it operates at a lower speed compared to a high-speed hand piece. The lower speed minimizes the risk of damage to the tooth structure and provides a smoother finish during polishing treatments.

In addition to polishing, the slow speed hand piece can also be equipped with various attachments, including straight and contra angle attachments, making it versatile for different dental procedures. Overall, its specific speed range is ideal for tasks that require a gentler approach, such as polishing enamel surfaces without causing harm.
