Appearance is not the only consideration
A veneer is typically a relatively thin restoration applied to the front surface of a tooth. A crown covers substantially more of the visible tooth. Although both may change appearance, the amount of remaining tooth, bite forces and underlying disease can make one more appropriate than the other.
When veneers are discussed
Veneers may be considered for selected aesthetic concerns such as shape, colour or minor visible irregularities. They are not a substitute for treating active decay or gum disease. Preparation requirements vary by material, technique and the patient’s tooth condition.
When crowns are discussed
Crowns are often used when a tooth needs more extensive structural restoration, including after significant damage. Choosing a crown solely for cosmetic reasons can involve more tooth preparation than another option would require. A clinical examination is needed to determine whether coverage is justified.
Durability and maintenance
Both types of restorations can chip, loosen, stain at margins or need future replacement. Grinding, clenching, oral hygiene and existing bite conditions influence their performance. Ask about expected maintenance and whether a protective appliance may be recommended.
Questions before consenting
Ask how much natural tooth structure will be removed, whether bonding or whitening could meet the same goal, which material is proposed, and what happens if the restoration fails. Photographs and a mock-up may help explain expected appearance, but cannot guarantee an exact result.
