What is Gutta percha primarily used for in dentistry?

Gutta percha is primarily used to fill tooth canals during root canal treatment. It is a biocompatible material that effectively seals the root canal space after the infected or damaged pulp has been removed. Its properties, including the ability to provide a good seal, resistance to moisture absorption, and easy manipulation, make it an ideal choice for ensuring that no bacteria can re-enter the canal and that the tooth remains functional after treatment.

The other options do not accurately reflect the primary use of gutta percha in dentistry. For instance, while teeth whitening involves different procedures and materials to lighten tooth color, gutta percha does not play a role in that process. Similarly, repairing fractures typically involves the use of restorative materials, such as composite resins or crowns, rather than gutta percha. Lastly, plaque removal is typically accomplished through scaling and polishing techniques rather than through the use of materials like gutta percha. Thus, the correct focus on gutta percha as a material specifically for filling tooth canals underscores its significance in endodontic treatments.
