What is a potential negative effect of polishing teeth?

Polishing teeth can lead to heat generation, which is a significant concern during the coronal polishing process. When polishing agents are applied to the teeth, the friction created between the polishing tool and the tooth surface can produce heat. This heat can be harmful, particularly if it causes discomfort or pain for the patient. Excessive heat may also affect the pulp of the tooth if it reaches high enough levels, potentially leading to sensitivity or other complications. Therefore, it's crucial for dental assistants to be mindful of the amount of pressure used and the duration of polishing to minimize heat generation while effectively cleaning the teeth. This understanding helps ensure that the polishing procedure is both safe and comfortable for patients.
