What should be avoided when using a prophy angle at high speed?

Using a prophy angle at high speed can lead to several issues, with heat buildup being a primary concern. When the prophy angle operates at high speeds, friction is increased between the instrument and the tooth surface. This friction generates heat, which can raise the temperature of the tooth structure and potentially damage the dental pulp, or cause discomfort and sensitivity for the patient.

Maintaining an appropriate speed helps manage this heat production, ensuring that coronal polishing is effective while minimizing any risks of thermal injury. Proper technique, such as using a light touch and frequently applying water to cool the area, can help prevent heat-related complications while polishing.

In contrast, excessive plaque removal and intense polishing affecting color do not specifically address the primary risk associated with high-speed use. Similarly, the application of fluoride is more about post-polishing care rather than a direct result of how the prophy angle is used at high speeds. Understanding the implications of friction and heat buildup is essential for safe and effective dental polishing practices.
