What is a consequence of inadequate cuspal coverage?

Inadequate cuspal coverage can significantly weaken the structural integrity of a tooth, particularly when it's been subjected to restorative procedures. When the cusps of a tooth do not receive adequate support from a crown or restoration, the mechanical forces from chewing and biting can lead to greater stress concentrations. This increased stress makes the tooth more susceptible to fractures, especially in heavily loaded areas.

While other options mention increased sensitivity and aesthetic results, these are not the principal concerns directly linked to inadequate cuspal coverage. The primary focus is on the structural vulnerability that results from insufficient support, which ultimately leads to a higher likelihood of fractures. Thus, the correct understanding revolves around how inadequate cuspal coverage compromises the tooth's ability to withstand occlusal forces, leading to greater chances of fractures over time.
