What is an important reason for stabilizing the handpiece during polishing?

Stabilizing the handpiece during coronal polishing is crucial for ensuring patient comfort and preventing injury to the surrounding oral tissue. When the handpiece is stabilized, the clinician can maintain better control over the polishing process, reducing the risk of applying pressure to soft tissues, such as the gums and cheeks. This helps to prevent accidental injuries that could lead to pain or discomfort for the patient.

Moreover, a stable handpiece allows for a more consistent application of the polishing paste on the teeth, which contributes to a safer and more effective polishing experience. Patient comfort is paramount in any dental procedure, and maintaining control over the handpiece directly influences the overall comfort level during treatment.

While avoiding excessive pressure on a single tooth is an important consideration, it is a component of the broader goal of ensuring patient comfort and preventing injury. The other options, while relevant to various aspects of the procedure, do not address the core necessity of handpiece stabilization in terms of patient safety and comfort as effectively as this choice does.
