What is one potential risk of performing coronal polishing without adequate training?

Performing coronal polishing without adequate training can significantly increase the risk of patient injury. Coronal polishing involves using a rotating rubber cup and abrasive paste to remove plaque and stains from the surfaces of teeth. If the dental assistant lacks the necessary skills and knowledge to perform this procedure correctly, they may inadvertently cause damage to the tooth structure or surrounding soft tissues. For instance, excessive pressure or incorrect angling of the polishing instrument can lead to enamel erosion, damage to the gingiva, or even trauma to the underlying pulp. Additionally, improper infection control practices during the procedure could expose patients to harmful pathogens. Therefore, appropriate training is essential to ensure that coronal polishing is performed safely and effectively, minimizing the risk of injury to patients.
