Veneers

Veneers

A dental veneer is a thin piece of either porcelain or composite resin that is attached to the front surface of a tooth. Veneers can be used to modify teeth that are discolored, worn, chipped, malformed, have spaces between them and the adjacent tooth, or are slightly misaligned. They modify and/or improve the appearance of the tooth. Veneers are frequently requested as patients increasingly want whiter and straighter teeth.

COMPOSITE OR PORCELAIN VENEERS?

Composite Veneers :

Composite resin veneers are the most commonly placed veneer for dental esthetic improvements. The procedure consists of applying a thin layer of composite resin, which is a tooth-colored filling material, to the front of a tooth that is to be modified and esthetically improved. Beautiful cosmetic results can be achieved by improving the appearance of the teeth.

Indications, Advantages and Limitations

Composite veneers are indicated for minor modifications of tooth shape or colour. Their advantages are that they are done in one appointment, there is no impression taking, no laboratory time is required, and they are the least expensive option. They are also repairable if chipped or broken, which porcelain veneers are not.

Their disadvantage is that composite resins are more porous and less resistant than porcelain to chipping or staining, and they lose their luster with time. Their longevity is 5-7 years.

Porcelain Veneers :

Porcelain veneers are commonly used in cosmetic dentistry to improve the appearance of teeth. They are custom-made to fit over teeth in order to dramatically improve the smile and appearance.

Porcelain veneers are thin laminates, about 0.5-0.7 millimeters thick, made of porcelain, that are bonded to the front surfaces of the tooth.

Indications, Advantages and Limitations

Porcelain veneers are used to correct more significant dental changes in shape, color and alignment.

Their advantages are their beauty and durability. They are stronger than composites and they do not change colour or stain.

Their disadvantages are that porcelain veneers are not done chairside.

They are fabricated in a dental laboratory and therefore require at least two visits. The porcelain veneers are more expensive than composite veneers, however their life expectancy can easily exceed 10 years.

This procedure takes two visits.

First, a thin layer of enamel is removed from the tooth surface, typically 0.3 to 0.7 millimeters. An impression is then taken and sent to a laboratory to fabricate a custom made porcelain veneer. A temporary acrylic veneer is placed on the tooth until the next visit.

On the second visit the permanent veneer is fitted and then bonded to the tooth.

What you need to know…

Veneers cannot correct all shapes, misalignments, and colour problems. Each case requires special consideration and proper diagnosis. Only your dentist can determine if veneers are appropriate for making the changes you need or want.

Good oral hygiene and regular dental examinations and cleanings can improve the durability and longevity of dental veneers. Deficient oral hygiene can lead to caries around veneers and failure. Meticulous brushing and flossing are essential to the success of any dental treatment.
