Dental crowns, or “caps,” are similar to veneers in that they cover up part of a tooth. The main difference is that a crown fits over the entire section of a tooth that is visible above the gums, while a veneer only covers the tooth’s front-facing surface.
In order to make room for a dental crown, more enamel must be shaved off of the tooth. So, veneers are usually considered the more conservative treatment that allows you to retain more of your natural tooth structure.
