What are the consequences of extracting a tooth with root caries?

• A. Spacing issues, drifting of retained teeth, and malocclusion of the neighboring tooth
• B. No change in alignment
• C. Cosmetic improvement only
• D. Immediate resolution of bite issues

Answer: (A)

When a tooth with root caries is removed, the arch loses a point of stability and support. The gap left behind creates space that adjacent teeth tend to fill, so they drift into the vacancy. This drifting often comes with tilting or rotation of the neighboring teeth and can alter the bite, producing malocclusion and overall alignment changes. Without timely replacement or space maintenance, the occlusion can become unstable, and even the opposing tooth may supra-erupt to try to occupy the space. These are the predictable, clinically significant consequences, which is why this option best describes what happens after extraction in the presence of root caries.
