When your teeth are chipped or cracked or stained, it is possible to create a paper thin porcelain laminate which can be addressed directly to your damaged teeth. In so doing, you can cover-up misaligned teeth or flaws and imperfections on a tooth-by-tooth basis. On its porcelain material is considered hard and brittle. However, when porcelain is bonded or affixed to a tooth acting as a structural substrate, then porcelain becomes a highly effective bonding material for the tooth. The result for the patient is that the tooth not only looks better instantly but also has gained a hard exterior surface protection.
Porcelain Reacts Like Real Tooth Enamel LikeAnother significant quality advantage of porcelain is that it carries translucency in much the manner that a tooth's enamel allows light to penetrate and create more of the 3-dimensional depth of the tooth. In earlier years, bonding materials, even porcelains, were at best semi-transparent, thus tended to reflect light in a manner uncharacteristic of teeth. The effect of increased light reflection from one bonded tooth would differentiate that tooth and draw attention to the cosmetic dentistry rather than create a "natural" look. Modern porcelains have overcome that flaw and now permit light to penetrate the outer surface into the structure of the tooth before reflecting back to the viewer. This area of cosmetic dentistry shows the effort by technologists to synthesize materials that will mimic mother nature.
Porcelain's surface is hard and smooth thus offers a limited surface opportunity for stains or discoloring to take hold as generally happens when foods such as grape juice, beets, wine, coffee or tobacco products come into regular contact with teeth. While deflecting stains, porcelain can be bonded at the site of past filings, or sites where small cracks or irregularities exist to create both protection and cosmetic improvement.
Porcelain Veneer Improves Upon Dental Bonding
In terms of quality of effect, the porcelain veneer is a cosmetic dentistry improvement over basic dental bonding. The porcelain veneer creates a far more natural finished appearance than does simple bonding. The achievement of superior effect comes at a price: porcelain veneer dentistry is considerably more expensive, plus porcelain veneer work is subject to breaking and damage, which hints at high future repair costs. Once a porcelain veneer is broken, then the entire porcelain veneer must be replaced. By contrast, dental bonding can be "spot repaired" at the broken line, and for lower costs to you.
