What is the action called when polishing agents are moved over a tooth surface?

1. Burnishing

2. Grinding

3. Cutting edge

4. Polishing action

The correct answer is: Cutting edge

The action described when polishing agents are moved over a tooth surface is referred to as polishing action. This process involves using abrasives or polishing agents that smooth and shine the tooth surfaces, effectively removing plaque, stains, and residues. Polishing helps improve the aesthetics of the teeth and can enhance the smoothness of the enamel, making it harder for plaque to accumulate. While burnishing typically implies a process of making a surface smooth and shiny through rubbing, it does not specifically pertain to the direct action of polishing agents on tooth surfaces. Grinding indicates a more abrasive action that removes material, which is not the primary goal of tooth polishing. The term cutting edge usually refers to a sharp boundary that cuts through substances, which also doesn't accurately represent the process of polishing teeth. Therefore, the term polishing action accurately captures the intention and mechanics involved in enhancing the surface of teeth using polishing agents.
