Your otherwise beautiful smile has one noticeable flaw — one or more of your teeth are deeply discolored or stained. More than likely this staining is deep within the teeth, what we refer to as intrinsic staining. There are a number of reasons this can occur — from fillings or use of antibiotics, for example — and our first approach should be to attempt a whitening technique.
However, if that doesn't produce the desired result, porcelain laminate veneers are another option you might consider. Veneers are made of dental porcelain, a bio-compatible material that can be shaped and colored to closely match neighboring teeth. After a minimal amount of tooth reduction (removal of some of the enamel from the tooth surface) to prepare for the laminate, the veneers are then permanently bonded to the tooth surface and cover the discolored natural tooth. Besides changing the appearance of discolored or stained teeth, veneers can also be used to correct other imperfections such as chipped or misshapen teeth.
Patients, however, have a common question: how long will the veneers last? With proper care, veneers can last anywhere from seven years to more than twenty years. It's possible, though, to damage them — for example, you can break them if you bite down on something that goes beyond the porcelain's tolerance range, such as cracking nut shells with your teeth (not a good idea even for natural teeth!). You should also keep in mind that veneers are composed of inert, non-living material and are attached and surrounded by living gum tissue that can change over time. This process may eventually alter your appearance to the point that the veneer may need to be removed and reapplied to improve the look of your smile.
If a veneer is damaged, all is not necessarily lost. It may be possible to re-bond a loosened veneer or repair a chipped area. The worst case is replacement of the veneer altogether. Chances are, though, this will only happen after the veneer has already served you — and your smile — for many years.

Our smiles are our “calling cards” for first impressions. When our front teeth are missing, chipped or otherwise damaged, it will certainly make an impression — and not a positive one.
The good news is many aesthetic problems with front teeth can be remedied with the use of composite resins. This cost-effective treatment choice not only minimizes a negative appearance, but can actually create a positive smile transformation.
Composite resins are tooth-colored materials made up of two or more polymer substances. We call materials like these biomimetic, meaning something non-living that’s fashioned to appear or “mimic” something living. Composite resins are made of substances that aren’t teeth, but fashioned to look and function like teeth.
Composite resin restorations are bonded to the outside of the tooth with dental adhesive, with little to no preparation of the enamel surface of the tooth. They’re best suited for teeth with minor to moderate damage from decay or trauma, but where the majority of the structure is still viable and intact.
These restorations require skill and an artistic eye to achieve the most life-like result. One of the most important considerations is tooth color. The natural color of your teeth is actually a combination of color from the inner core of the tooth, the dentin, and the outer enamel layer. Much of the color comes from the dentin as it shows through the translucence of the enamel. The intensity and hue also changes along the length of the tooth — there are subtle zones of color that run vertically along the length of the crown (the visible portion of the tooth). Our aim is to replicate this variety of color in the restoration and affix it in such a way that it blends with the natural color of surrounding teeth.
Composite resins aren’t the best option for all situations; depending on the tooth’s condition and location, a porcelain veneer may be the better choice. After a thorough dental examination, we can make the best recommendation for your situation. If conditions are right, a composite resin restoration could transform your smile and your life.
