The dental veneers
represent thin shields that are placed over the surface of the teeth. The goal is to protect the damaged tooth surface and to enhance its aesthetics. Two types of restorative materials are used in the production of dental veneers: composite resin and porcelain. Dental composites
consist of Bis-GMA monomers, silica fillers, and photoinitiators. Porcelain represents ceramic material that is usually produced from kaolin. Both types of veneers can be produced by a dental technician working in a dental laboratory setting. Moreover, the composite veneers may be fabricated inside the patient`s mouth at the dental surgery
The teeth require a minimum amount of preliminary preparation prior to the actual implementation of the veneers. Typically, the teeth are reduced by 0.5 mm under no or little local anesthetic. Some dental veneers will be placed without any drilling. They will be produced so as to fit on the top of the tooth. However, these veneers apply to limited exceptions as the teeth may become too large in size. Individuals with a class III bite will not benefit from dental veneers. The lower jaw of these patients protrudes further than their upper jaw. So, there is a risk that the lower jaw teeth will bump into the upper jaw teeth and this will displace the veneers.
On the other hand, the dental veneers are beneficial in numerous cases. For instance, some individuals have mal-positioned teeth. The use of multiple veneers can help by closing gaps between the teeth. The procedure will cover their building in uniformly colored and symmetric shapes. Moreover with the passage of time, the hard and white substance that covers the teeth, the enamel, becomes worn and dulled. This may result from genetic predisposition or improper dietary habits. The dental veneers fix these problems as they may be placed over fractured, discolored, or small sized teeth. In any case, dental veneers have aesthetically pleasing effect and eliminate the need of a more intrusive teeth preparation as required by dental crowns
