What is the recommended speed of the handpiece during coronal polishing?

The recommended speed of the handpiece during coronal polishing is typically in the range of 10,000 to 30,000 RPM. This speed is optimal for effectively polishing enamel surfaces without causing damage to the tooth structure or the surrounding gum tissue. At this RPM range, the handpiece allows the dental hygienist or dental assistant to achieve a smooth finish while maintaining adequate control and minimizing the risk of overheating the tooth or causing discomfort to the patient.

Faster speeds, such as those above 30,000 RPM, may increase the likelihood of damaging the enamel or producing excessive heat, which can lead to pulp irritation. Slower speeds, below 10,000 RPM, may not provide enough abrasive action to effectively polish the teeth, reducing the efficacy of the procedure. Thus, the 10,000 to 30,000 RPM range strikes a balance between efficiency and safety during coronal polishing procedures.
