What is the primary function of flux in dental procedures?

The primary function of flux in dental procedures is to protect metals, such as alloys, from oxidation during the heating process. When working with dental materials, especially those that are melted to create restorations or repairs, it is crucial to prevent oxidation from occurring, as this can lead to contamination of the alloy and compromise the quality and integrity of the final product. Flux serves as a protective barrier, allowing for cleaner melting and better bonding of materials by forming a layer that keeps oxygen away from the molten metal.

This protection from oxidation is essential for ensuring successful soldering or joining processes in dentistry, leading to stronger and more durable restorations.
