- A dental veneer is an ultra-thin shell of tooth-colored porcelain or composite that is cemented over the facial
surfaces of your teeth to correct dental issues including worn tooth enamel, uneven tooth alignment or spacing,
tooth discoloration, and chips or cracks.

compared to crowns.
- Composite resin veneer- consist of a mixture of two or more materials
- Advantage

porcelain veneer needing just the one visit.
- They can be repaired if broken by the dentist, usually by adding on
to the remaining veneer instead of replacing the entire thing.
- Disadvantage
- They have a tendency to stain due to the patients diet.
- Porcelain veneers- built in a lab by technicians
- Advantage

- obtain a better aesthetic value compared to composites, the
glass-like nature allows light to penetrate acting true to nature of the
enamel of the tooth. This creates a lustrous appearance close to the
true appearance of enamel.

- Porcelain veneers may break meaning the entire thing will need to be
removed and replaced being made by a lab technician.
