Comparison between Composite And Porcelain Veneers
Porcelain veneers are long lasting, more beautiful to look at but at the same time they are more expensive also. In comparison, composite veneers are less expensive but they do not last long and their aesthetic is poor as compared to porcelain veneer.
Enamel Veneers
It is new innovation in the clinical dentistry. An Enamel Veneeris a thin nail like shell of enamel, which is obtained from natural tooth of an individual with a help of rotary instruments, in a predetermined precise manner.

Contraindications

The teeth are discolored and require change of shade in the final result.
When Proclination is due to skeletal overgrowth.
In periodontally compromised teeth with lack of bone support and severe mobility.
Advantages
Less time consuming
Immediate results.
Less expensive.
Maintain natural form and color.
Veneers vs. Bleaching/Whitening
Now question arises whether veneers are better or bleaching/whitening is better. When the teeth are mildly discolored, in that case tooth bleaching is better and more cost effective than veneers as in this dentist does not have to shape or prepare the tooth to place the veneer. But if the teeth are severally stained or they are chipped/damaged or cracked then veneers is the only choice. Veneers have added benefit of better aesthetics, longer life and less invasive. With whitening or bleaching procedure, we are not very sure about the ultimate result i.e. how much white the teeth will become but with porcelain veneers, one can decide about the shade and size before hand only. So if one wants white, healthy, natural looking and well aligned teeth, then veneers is the only answer
