The major disadvantage of Gutta Percha is its potential weakness, particularly in narrow canals. This material, while widely used in endodontics for root canal filling, may not provide sufficient support in very narrow or irregularly shaped canals. The structural integrity needed in such cases can be compromised, potentially leading to treatment failures, as the material is not rigid enough to withstand forces if the tooth experiences stress during function.

Though there are other downsides associated with Gutta Percha, such as its solubility in certain solvents or issues regarding its long-term dimensional changes, the specific concern about its inability to provide adequate strength in narrow canals is a notable drawback in clinical practice. The other options mentioned do not reflect the critical mechanical considerations that practitioners have to account for when selecting materials for different canal shapes and sizes.
