Broadly speaking veneers are thin flakes of dental ceramics or photopolymer. They are used to replace damaged or unsightly front surface of the teeth and thus change to better their vision. Veneers are solutions to problems in the field of smile as fractures, distance between teeth, light distortion, staining, bad ordered, caries and others. Veneers are placed on the outer part of the tooth that is closer to the mouth.
Their average thickness is 0.5 mm. Prior to affix the top surface of the tooth is thinning while consuming no more than 30% of its volume. This is one of the advantages of the veneer to the crowns in which the tooth can take up to 70% by volume. This amount is particularly invasive given that in some cases the tooth is vital ( alive, not killed ).
Types of veneers:
According to the material of which are made the facets are divided ceramic and photopolymer.
According to the way in which they are placed are direct or indirect.
Direct veneers are called bonding. The work on them is performed directly into the mouth of the patient. Made of hardened resin ( photopolymer ). They are cheaper than porcelain veneers. On average in good care endure between 8 and 10 years. Main disadvantages include the ability to change color over time and fall the splendor achieved by polishing.
Indirect veneers are manufactured by a dental technician after taking an impression of file down and prepared by the dentist teeth of the patient. Veneers are made of porcelain which implies their endurance – about 15 years. Another advantage of this type of intervention is that the material does not change its color over time, spares gums and color can be selected to blends with the other teeth to no difference. Quality of course has its price. Porcelain veneers are more expensive than bonding. Putting them requires precision, so if you choose this method – choose carefully the specialist who will deal with your case.

To last longer and to be in better appearance veneers require maintaining good oral hygiene – brushing and toothpaste, using a dental floss and antibacterial mouthwash.
If the correct shade is selected and placed precisely the teeth with the facets will not differ from the natural.
The time required for the manufacture of porcelain veneers varies in different laboratories but the estimated period is 20 days.
It is wrong to believe that veneers can harm teeth and accelerate the onset of caries.
Veneers are placed only on natural teeth. They can not be put on crowns or in the absence of real teeth.
