What complication may arise from excessive pressure during coronal polishing?

Excessive pressure during coronal polishing can lead to enamel abrasion or damage to the gingival tissues. Coronal polishing involves using a rotating rubber cup loaded with polishing paste to smooth and shine the surfaces of teeth. However, if too much pressure is applied, it can wear down the enamel excessively, resulting in it becoming thinner over time, which may lead to increased sensitivity and other issues.

In addition, applying excessive pressure on soft and delicate tissues such as the gums can cause trauma. This may result in inflammation, bleeding, or other forms of tissue damage. Maintaining a proper technique with appropriate pressure is essential to avoid any harm and to ensure the tooth enamel remains intact and the adjacent gingival tissues are supported and healthy.
