Which statement best describes the effect of a poorly fitting denture?

• A. Poorly fitting prosthesis
• B. Overly long denture borders
• C. Excess saliva
• D. Improper occlusal contacts

Answer: (A)

A poorly fitting denture primarily shows up as instability and poor seating. When the prosthesis doesn’t fit well, it moves or rocks during function and can’t establish a stable seal against the tissues. That instability underlies the main consequences: tissue irritation or soreness from pressure points, reduced retention and stability, and compromised chewing and comfort. Describing it as a poorly fitting prosthesis effectively captures this overall issue—the denture itself is not fitting correctly, which explains the movement and the tissue response.

Other options reflect possible related problems, but they are not the overarching description of the effect. For example, borders that are too long can irritate tissues and affect fit but are more specific; excess saliva can occur with irritation, yet it isn’t the defining outcome; improper occlusal contacts may result from poor fit, but that is a consequence rather than the broad effect itself.
