**Question:** Undersurface of pontic should be

A. level with the adjacent tooth cusps
B. lower than the adjacent tooth cusps
C. higher than the adjacent tooth cusps
D. flush with the adjacent tooth cusps

**Core Concept:** In dentistry, the pontic is a false tooth or part of a dental prosthesis (e.g., fixed partial denture or bridge) replacing one or more missing teeth. The undersurface of a pontic is the surface in contact with adjacent teeth during function.

**Why the Correct Answer is Right:** The undersurface of a pontic should be **level with the adjacent tooth cusps**. This ensures proper functioning of the prosthesis by distributing the occlusal forces evenly on the supporting teeth, preventing excessive strain on any single tooth and maintaining proper occlusion (bite). The goal is to mimic the natural dentition as closely as possible.

**Why Each Wrong Option is Incorrect:**

A. **"Leveling the pontic with adjacent tooth cusps" maintains the natural occlusal plane and prevents excessive strain on any single tooth, ensuring a stable and functional restoration.

B. **"Lowering the pontic below the adjacent tooth cusps" would result in an abnormal occlusal plane, leading to uneven distribution of occlusal forces and potential tooth wear, tooth sensitivity, and discomfort for the patient.

C. **"Raising the pontic above the adjacent tooth cusps" would also lead to an abnormal occlusal plane, causing similar issues as option B.

D. **"Matching the pontic with the adjacent tooth cusps" would not ensure even occlusal force distribution, potentially causing tooth wear, sensitivity, and discomfort for the patient.

**Clinical Pearl:** Proper pontic design ensures a functional and esthetic restoration in prosthodontics, preventing complications and providing patient comfort.

**Correct Answer:** D. level with the adjacent tooth cusps
