Veneers are custom made porcelain or composite wavers that is being placed over the fronts of the teeth to enhance their appearance and also to repair damage.
Veneers are divided into two sub-types:

Direct veneers –
these are composite restorations bonded directly onto the teeth
Indirect veneers –
made in the laboratory of porcelain/ceramic materials and then bonded onto the teeth

1. Improve color of teeth ( they can whiten stained or discolored teeth )
2. Close spaces between teeth
3. Replace bonding ( increased longevity )
4. Change shape of teeth ( correct a “crooked” smile without the need for     braces )
5. Maintain tooth structure
