Direct Veneers :

A direct veneer is built up over the tooth surface by hand. It is most commonly done using tooth coloured composite resin.Direct veneers are a more simple procedure, and are generally done in a single appointment. They are less expensive but do tend to deteriorate more quickly and rarely get the high level of aesthetics that indirect veneers achieve.

Indirect Veneers : 
An indirect veneer is made in a dental laboratory and is generally constructed from porcelain.Indirect veneers usually require two appointments. The first is when the preparation and impressions are done; the second is when the veneer is fitted.They are more expensive as compared to direct veneers and their life is also more as compared to direct veneers.
