What effect does over-polishing have on tooth enamel?

Over-polishing tooth enamel can significantly compromise its integrity by causing surface abrasion. This process involves the removal of the outermost layer of enamel, which is crucial for protecting teeth from decay and other forms of damage. As this protective layer wears down, the underlying dental structures can become exposed or more susceptible to external stimuli.

Increased sensitivity is a common consequence of over-polishing. When the enamel is eroded, the dentin layer beneath it may be exposed, which can lead to discomfort or pain when consuming hot or cold foods and beverages. This heightened sensitivity can also affect a patient's overall comfort and dental health, making it essential for dental professionals to apply coronal polishing techniques judiciously.

In contrast to over-polishing, methods that strengthen enamel or enhance its luster involve gentle, controlled polishing that respects the enamel's natural protective layer. Understanding these distinctions is vital for performing effective and safe coronal polishing procedures.
