Existing fillings sometimes need to be replaced due to wear, chipping, or cracking. Many people use this opportunity to replace their silver amalgam fillings with natural, tooth-colored composites. Their reasons may be aesthetic, or concern over the safety of amalgam fillings, which contain mercury. Composite fillings tend to wear out sooner than silver fillings in larger cavities, although they hold up as well in small cavities.
Veneers are wafer-thin, custom-made shells that cover the front surface of teeth. Bonded to the front of the teeth, changing their color, shape, size or length, veneers can be made from porcelain or resin composite. Veneers offer a conservative approach to changing a tooth’s color or shape compared to crowns, but the process is not reversible.
A combination of dental techniques can be used to achieve a great smile. Here, porcelain veneers and crowns correct crooked teeth, an uneven gum line, and other chipped, worn, and discolored dentistry. While cosmetic dentists can make a dramatic difference in a person’s smile and overall oral health, the work must be carefully planned — though for many the elaborate and costly production is worth it in the end.
