Which tool is designed to smooth between the tooth and aproximal surfaces?

Finishing strips are specifically designed for smoothing surfaces, including the spaces between teeth and their proximal surfaces. These strips typically have a thin, flexible design that allows them to fit easily into the tight areas between teeth. They come in various grits, enabling dental professionals to effectively polish and refine composite restorations and remove any rough edges or excess material. This attention to detail is crucial for achieving optimal aesthetics and functionality in dental work.

In contrast, a bur changer tool is used to facilitate the quick exchange of dental burs during procedures, improving efficiency but not related to smoothing surfaces. A luting agent is employed for cementing restorations or crowns, serving a different purpose in tooth restoration. An articulating paper holder is used to hold articulating paper, which helps assess occlusion during bite adjustments but does not contribute to smoothing tooth surfaces. Thus, finishing strips are the appropriate choice for their intended function in dental treatment.
