Zirconium silicate is primarily used in dentistry for its properties that allow it to effectively remove stains and for polishing surfaces. This material is valued for its ability to create a smooth, polished finish on dental restorations and to enhance the aesthetic appearance of teeth by eliminating unwanted discoloration.

The use of zirconium silicate in polishing is particularly beneficial because it can help maintain the integrity of dental materials while achieving a high-gloss finish that is desirable in cosmetic dentistry. Such polishing also plays a critical role in reducing plaque accumulation and overall maintenance of oral hygiene.

While other options pertain to various dental practices, they do not accurately capture the primary function of zirconium silicate, which is centered on stain removal and polishing rather than instrument cleaning, cavity filling, or strengthening dental materials. Each of those tasks typically involves different materials specifically designed for those purposes.
