When using a high-speed handpiece for tooth material removal, how should the pressure be applied?

When using a high-speed handpiece for tooth material removal, applying a feather-light touch is the best practice. This technique allows for more precise control and reduces the risk of damaging the tooth or surrounding structures. High-speed handpieces are designed to operate efficiently with minimal resistance; therefore, they do not require excessive pressure to achieve effective cutting.

Applying light pressure enables the bur to engage appropriately with the tooth structure, resulting in smooth and efficient material removal. It also helps in maintaining the integrity of the tooth and minimizing heat generation, which can cause discomfort or pulpal damage if excessive pressure is applied. A gentle touch allows for better visualization of the working field, enhancing overall accuracy during the procedure.

In contrast, applying firm, heavy, or even excessive pressure can lead to a number of complications, such as increased wear on the instruments, thermal injuries to the tooth, or unwanted trauma to adjacent soft tissues. A feather-light approach is therefore crucial for successful tooth preparation and optimal patient safety during dental procedures.
