Coronal Polishing Practice Test 2026 for Dental Assistants Certification

The largest ingredient in prophy pumice is the abrasive component. Prophy pumice is specifically formulated for dental polishing, primarily to remove stains and plaque from the surface of teeth. Abrasives, such as pumice, are gritty substances that help in mechanically scrubbing the tooth surfaces, making them smooth and shiny.

The effectiveness of prophy pumice largely relies on the size and quality of its abrasive part, which is designed to be efficient yet safe for dental enamel. The formulation balances the abrasive properties with other ingredients, but the predominant volume is typically made up of the abrasive to ensure optimal polishing results. This characteristic distinguishes prophy pumice as a practical and necessary tool in dental hygiene practices.

Other components—like water, humectants, and binding agents—play supporting roles in the formulation, serving functions such as maintaining moisture, improving texture, and ensuring the product remains stable. However, they do not constitute the primary component that provides the main cleaning action associated with prophy pumice.
