What risk is associated with removing cement when it is not fully set?

When cement is removed before it has fully set, one significant risk is breaking the seal between the tooth and the prosthesis. This seal is crucial for ensuring that the prosthesis fits properly and remains firmly attached to the tooth. If the cement is not adequately set before removal, it may not create a proper bond, which can lead to microleakage, compromise the longevity of the prosthesis, and potentially allow bacteria to enter, increasing the risk of decay or infection.

Choosing this option highlights the importance of allowing dental materials, such as cement, to fully cure as intended, as it directly impacts the effectiveness and success of the dental procedure. On the other hand, the incorrect options discuss outcomes that do not align with the consequences of prematurely removing unset cement. For instance, aesthetics and bonding strength would not be enhanced by improper removal, and tooth sensitivity would not necessarily decrease as a result of cement removal; in fact, it could lead to an increase in sensitivity if the seal is broken.
