How does the alveolar crest appear between anterior vs posterior teeth?

• A. Pointed and sharp between anterior teeth; smooth and flat between posterior teeth.
• B. Flat between anterior; pointed between posterior.
• C. Uniform along both.
• D. Absent between anterior teeth.

Answer: (D)

In healthy dentition, the alveolar crest shows a distinct difference between front and back teeth. Between the front teeth, the interproximal alveolar crest tends to be sharp and pointed. This reflects the snug contact and closer root proximity in the anterior region, which creates a more peaked crest of bone. Between the back teeth, the crest is flatter and smoother because the roots diverge more and the interproximal space is broader, leading to a broader, less peaked crest.

The crest is present around every tooth pair; saying it’s absent between the front teeth contradicts normal anatomy, and the other descriptions don’t align with the typical anterior vs posterior pattern in healthy conditions.
