What is the major disadvantage of Gutta Percha?

The major disadvantage of Gutta Percha, particularly in the context of endodontic treatment, is its weakness when it comes to providing adequate support within narrow canals. While Gutta Percha is favored for its sealing properties and biocompatibility, its mechanical properties can sometimes be insufficient, especially in the case of narrow or complex canal systems. This weakness can lead to challenges in maintaining the integrity and stability of the filled canal over time, which may ultimately affect the long-term success of the root canal treatment.

Weakness in narrow canals can result in devitalized tissue or reinfection if the filling material does not adequately withstand the forces exerted during normal chewing or other stress factors. It is crucial for dental professionals to consider the physical properties of the materials used in root canal filling to ensure long-term success.

The other options, while they indicate potential issues related to Gutta Percha, do not represent the primary disadvantage. For example, while Gutta Percha is indeed soluble in certain solvents like chloroform, this property can be managed with appropriate techniques. Similarly, it can be difficult to remove Gutta Percha from canals if retreatment is necessary, and its tendency to shrink over time may pose risks, yet these factors do not
