In the golden proportion for anterior teeth esthetics, the maxillary lateral incisor width should be what percentage of the central incisor width?
Show answer and explanation
Correct answer: B. 60%
The golden proportion in dental esthetics dictates that each tooth should be approximately 60% the width of the tooth to its mesial side when viewed from the front. Specifically: the lateral incisor should be ~60% of the central incisor width, and the canine should be ~60% of the lateral. This creates a harmonious, naturally proportioned smile.
- A. ❌ 50% would make the lateral incisor appear too narrow — disproportionate.
- B. ✅ 60% — the golden proportion; lateral incisor is 60% the width of the central incisor.
- C. ❌ 70% makes the lateral too wide — reduces the natural difference in tooth widths.
- D. ❌ 80% makes the lateral nearly as wide as the central — unnatural appearance.
