What's the difference between caps and veneers?

Coverage: Typically, a "cap" -- also called a "crown" covers an entire surface of the tooth. A "veneer" is a laminate, and often placed only on limited surfaces of the tooth: it may be only outside (lip- or cheek-side), or have some "wrap-around" design that covers a portion of other surfaces. Also, veneers are typically thinner, and tooth may be reduced less for veneers than crowns/caps.

Big difference: caps are full coverage crown (porcelain around the whole tooth) Veneers are 0.3-0.5 mm porcelain covering just the front area of the tooth. You have to see the dentist to find which is best for you.

What to use and when: The major difference between a porcelain veneer and a crown is the amount of natural tooth structure that needs to be replaced. Therefore, these two types of dental restorations do have different structural characteristics. The secret to a successful results is to know what to use and when to use it.

A lot: Caps is the same thing as a crown. The tooth is reduced and a full covering is placed, Veneers by definition are the facings placed on the outside of the teeth
