What is the primary role of a pontic in dentistry?

Support for an orthodontic device
Replacement for a missing tooth in a bridge
Alignment of teeth
Prevention of tooth decay

The correct answer is: Replacement for a missing tooth in a bridge

The primary role of a pontic in dentistry is to serve as a replacement for a missing tooth in a dental bridge. A pontic is the part of a bridge that fills the gap left by a missing tooth, effectively restoring both the function and aesthetics of the patient’s smile. This prosthetic component is anchored to adjacent teeth, known as abutments, providing stability and support. By replacing the missing tooth, the pontic helps to maintain the alignment of the remaining teeth, prevents the shifting of adjacent teeth into the gap, and helps with proper chewing function. This role is essential in ensuring that dental bridges can fulfill their purpose of providing a functional and cosmetically pleasing solution for tooth loss. Other options, while related to dental practices, do not accurately describe the specific function of a pontic. For instance, orthodontic devices serve different purposes related to alignment, and prevention of decay focuses on oral health rather than restoration.
