Cosmetic Dentistry with Veneers
Porcelain veneers are one of the marvels of modern Houston cosmetic dentistry, made possible by technological improvements in materials. Porcelain is a material that can be made to closely resemble tooth structure and it has become possible to make it in very thin slices of less than half a millimeter thickness which makes it ideal to put on to the front of teeth to hide any discolorations or restore the shape where a small piece of tooth has chipped off. The other part of the process has been to develop a way of permanently bonding to the tooth surface these ultra-thin porcelain veneers since ordinary dental cements just aren’t strong enough or would leach away as they dissolve in oral saliva.
A clever way of overcoming the problem has been developed by using an acidic gel painted over the tooth surface for a few seconds which causes a slight roughening of the surface by dissolving some elements of the enamel. This produces thousands of tiny tags on a microscopic scale which can form a tremendously strong mechanical bond when a low viscosity, i.e. runny resin is flowed in which then sets hard. Resin composites in low viscosity thus provide the bond between the porcelain of the veneer and the tooth surface and spread evenly over the whole area as a very thin film provide a very strong bond indeed.
The resin cements used are usually dual cure which means that they set slowly by chemical means giving the dentist a chance to get the placement exactly as it should be, but can also be set quite quickly by using a powerful halogen light. This means that once the veneer is in the right place it can be bonded on command by using the light which penetrates the porcelain and sets the resin.
Even though the veneers are extremely thin they have an opaque layer incorporated which is sufficient to mask even the darkest color tooth beneath and thus can make good the appearance of a dead tooth that has been root-filled but is intact and doesn’t require a full crown.
There are several different brands of porcelain veneers but they are all technically very good and your Houston dentist will be able to decide which is best for your particular needs. Porcelain is a very tooth-like material and absolutely ideal in terms of appearance for improving the look of teeth, and, as long as it is carefully bonded across its whole area can give a long lasting fabulously beautiful result.
