Which oral conditions may increase the risk of enamel damage during polishing?

Weak enamel or significant demineralization may increase the risk of enamel damage during polishing because the structural integrity of the enamel is compromised in these conditions. Healthy enamel is strong and resilient, making it less susceptible to abrasion from polishing agents. When enamel is weak, however, it may not withstand the mechanical action of polishing, which can lead to further wear and potential damage.

Significant demineralization indicates that minerals have been lost from the enamel surface, resulting in a porous structure that is more vulnerable to abrasion. This can allow polishing materials to not only wear away the weakened enamel but also potentially exacerbate existing issues, such as sensitivity or decay.

Additionally, the presence of plaque and gum disease do pose risks to oral health, but they do not directly refer to the structure of the enamel itself. Plaque consists of bacteria and can lead to further tooth decay if not removed, but it is the condition of the enamel that primarily determines the risk during polishing procedures. Hence, recognizing weak enamel or significant demineralization is crucial for ensuring safe and effective coronal polishing treatments.
