Which statement correctly contrasts a dental crown with a dental veneer?

• A. A crown covers the entire tooth and restores function, while a veneer covers only the facial surface cosmetically.
• B. A crown requires minimal tooth reduction.
• C. A veneer provides full tooth replacement.
• D. A veneer is used for structural support in posterior teeth.

Answer: (A)

A dental crown and a dental veneer serve two different purposes and cover the tooth in different ways. A crown encases the entire tooth, rebuilding its shape, strength, and bite so it can function normally and resist chewing forces. A veneer is a thin shell bonded to the front surface to improve appearance; it doesn’t cover the whole tooth or restore function to the same extent. Because a crown must fit over the whole tooth, it requires substantial tooth reduction, while a veneer needs less preparation since it only modifies the visible facial surface. The other statements misstate either the coverage or the function of veneers and crowns.
