Which tool is commonly used for coronal polishing?

The commonly used tool for coronal polishing is the low-speed handpiece equipped with a rubber cup. This equipment is specifically designed for polishing the surfaces of teeth. The rubber cup spins at a low speed, allowing for gentle and effective removal of plaque, stains, and deposits from the enamel without causing damage to the tooth structure.

Using a low-speed handpiece retains a level of control that is essential for polishing, as it minimizes the risk of overheating the tooth or causing discomfort to the patient. Additionally, the flexibility of the rubber cup allows it to adapt to the contours of the teeth, ensuring a thorough polish.

In contrast, other tools such as a water flosser are intended for cleaning between teeth rather than polishing tooth surfaces. An ultrasonic scaler is used for calculus removal and may not provide the fine polishing effect desired after scaling. High-speed burs are more suited for cutting or removing dental hard tissue rather than polishing, as they operate at higher speeds and can be too aggressive for a polishing procedure. Thus, the low-speed handpiece with a rubber cup remains the appropriate choice for effective coronal polishing.
