Final answer:
Polishing agents mixed with water or mouthwash create a suspension used for tooth polishing. Abrasives in the agents help in removing plaque and stains from the teeth and contribute to oral hygiene.
Step-by-step explanation:
Polishing agents are available as commercial premixed pastes or as powders mixed with water or mouthwash to form a suspension used on the polishing cup. In dental care, abrasives play a significant role in maintaining oral hygiene by removing plaque and stains from tooth surfaces. These abrasives can be various compounds such as calcium carbonate, silicas, and aluminum hydroxide.
Although abrasive substances can cause a small amount of enamel erosion, they are essential for polishing teeth, which helps to prevent the buildup of tartar and minimize cavities as well as periodontal disease. Toothpaste not only contains abrasives but also fluoride which is crucial for preventing tooth decay.
