What is the role of a pontic in a dental bridge?

The role of a pontic in a dental bridge is to replace a missing tooth. A pontic is the prosthetic tooth that is suspended between the anchoring teeth, known as abutments. It plays a crucial function in restoring both the aesthetic appearance and the functionality of a patient's dental arch by filling the gap left by a lost tooth. This not only helps in chewing and biting but also helps maintain the alignment of surrounding teeth and preserves the structure of the jawbone.

The other options highlight different functions related to the bridge but do not accurately describe the specific function of the pontic. For instance, while the abutments support the entire structure of the bridge, they are distinct from the pontic itself. Similarly, the pontic does not serve as the fixed point or connect the bridge to dental implants; those responsibilities fall to the abutment teeth or implants, respectively. Understanding these distinctions helps clarify the specific roles each component plays in a dental bridge.
