One of the best restorative options for slightly deformed, misaligned or stained teeth is a porcelain veneer. Composed of thin, laminated layers of dental material, the veneer is bonded to the outside of the tooth to transform both its shape and color to blend with other natural teeth.
Veneers are more than a technical process — they’re works of art produced by skilled artisans known as dental lab technicians. They use their skills to shape veneers into forms so life-like they can’t be distinguished from other teeth.
How technicians produce veneers depends on the material used. The mainstay for many years was feldspathic porcelain, a powdered material mixed with water to form a paste, which technicians use to build up layers on top of each other. After curing or “firing” in an oven, the finished veneer can mimic both the color variations and translucency of natural teeth.
Although still in use today, feldspathic porcelain does have limitations. It has a tendency to shrink during firing, and because it’s built up in layers it’s not as strong and shatter-resistant as a single composed piece. To address these weaknesses, a different type of veneer material reinforced with leucite came into use in the 1990s. Adding this mineral to the ceramic base, the core of the veneer could be formed into one piece by pressing the heated material into a mold. But while increasing its strength, early leucite veneers were thicker than traditional porcelain and only worked where extra space allowed for them.
This has led to the newest and most advanced form that uses a stronger type of glass ceramic called lithium disilicate. These easily fabricated veneers can be pressed down to a thickness of three tenths of a millimeter, much thinner than leucite veneers with twice the strength.Â And like leucite, lithium disilicate can be milled to increase the accuracy of the fit. It’s also possible to add a layer of feldspathic porcelain to enhance their appearance.
The science — and artistry — of porcelain veneers has come a long way over the last three decades. With more durable, pliable materials, you can have veneers that with proper care could continue to provide you an attractive smile for decades to come.

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.

Today's cosmetic dentist can bring amazing transformations to their patient's smiles. That's because we now have a versatile array of materials and processes that precisely replicate the appearance of natural teeth.
Two of the most useful are porcelain veneers and crowns. Although different in structure and function, veneers and crowns both utilize a material known as dental porcelain, a ceramic material that can be shaped to resemble an individual patient's natural tooth shape, with the same color, hue saturation and translucence as the original or surrounding teeth.
As the name implies, veneers are a thin layer of dental porcelain that adheres to the outer surface of a tooth, essentially as a replacement for enamel. They solve a number of esthetic issues patients have with their teeth, especially those in front: poor color, shape and contours; broken teeth; poor tooth position; and staining that can't be removed with conventional bleaching. They most often require minimal tooth preparation, as only 1 mm or less of tooth enamel needs to be removed. Occasionally, no tooth reduction is required.
However, they are not a good solution where there is not an adequate amount of tooth structure to work with. In this case, a crown may be the best choice. A crown (or cap) covers the remaining tooth structure completely, reinforcing the remaining tooth structure 360°. This is an excellent choice for patients who have lost a large amount of tooth structure due to decay, trauma or grinding habits that have eroded the enamel.
To determine if you are a true candidate for either of these applications you should undergo a smile analysis in our office. During this process it's even possible to create a diagnostic mock-up — a “trial smile,” if you will — with temporary tooth-colored materials applied to your teeth and then photographed for your review.
The smile analysis helps us recommend the best solution for you and in turn will help you make an informed choice on the right application for you. Although either option may not be feasible in all situations, they may just be the right choice to change your smile for the better.

There are a number of materials and techniques available in cosmetic dentistry that help us improve our patients' smiles. Porcelain veneers stand out as one of the most popular and least interventional of these options.
As the name implies, a veneer is a thin layer of dental restorative material that covers the original tooth surface. Veneers don't require an extensive amount of tooth preparation or removal of sound tooth structure, as with a crown or bridge.
Veneers are made of dental porcelain, a material compatible with living tissue and with a very life-like appearance. The dentist as artist can fashion the porcelain to precisely imitate an individual's natural teeth, including the natural color and hue of surrounding teeth.
Are porcelain veneers an option for you? Only a smile analysis in our office can determine that. Your teeth must be in a somewhat normal position. The teeth in question must have a sufficient amount of remaining tooth structure to support veneers. And you must have symmetrical gum contours that will allow for proper framing of the teeth, which will enhance the final cosmetic result.
If your current dental health meets these criteria, then porcelain veneers could help correct spaces between teeth that aren't too wide, improve poor color, or address poor shape, contours or minor bite problems. Veneers, however, do have their limitations. They aren't effective if you have poor tooth position, if the root positions are widely out of line, or if you have a poor profile. Some form of orthodontics may be needed initially for these situations.
That being said, porcelain veneers are an excellent long-term option in the right situation. Depending on your individual circumstance and how you care for your teeth, a veneer application can last for several years, or if they come loose or become chipped they can be repaired in most cases. The material is strong enough to withstand normal pressures exerted during chewing or biting, as long as you avoid activities like opening nutshells with your teeth or chewing on very hard candy.
Overall, porcelain veneers can give your smile a whole new look with little impact on your remaining tooth structure.

You may have heard the term “veneer” with reference to woodworking, where it means a thin layer of attractive wood that covers and enhances the surface of a piece of furniture. Exactly the same principle applies to porcelain veneers used in dentistry: A thin layer of ceramic material is used to cover parts of a tooth in order to improve its structure and appearance.
Porcelain is a non-metallic ceramic material that is fired in an oven at a high temperature to make it hard and durable. Dental porcelain veneers are thin layers of ceramic that can be applied to the outside of the tooth so that the end result mimics the natural color and translucency of tooth enamel. The underlying tooth structure has to be prepared by removing a small amount of the enamel, about 1 mm, which the veneer replaces. The veneer is then bonded to the prepared surface using a light-sensitive resin.
In woodworking, a veneer may be used to match the grain between the left and right sides of a piece of furniture, creating a beautiful effect on a curve, or simply to bring the appearance of expensive wood to a backing that is less expensive.
Just as a wood veneer improves the appearance of a dresser or table, porcelain laminate veneers may be used to improve teeth that have a number of cosmetic and functional problems. These include staining that cannot be removed by tooth whitening, teeth that are too small, misshapen, chipped or spaced too far apart. After an assessment of your teeth and your smile, we can create a mock-up using temporary tooth-colored materials so you can decide whether the suggested changes will work for you, or you can make suggestions for further improvements.
Porcelain laminate veneers may not be the best solution for you if your teeth are severely stained or damaged. In cases where a large proportion of the original tooth must be replaced, porcelain crowns may be the best solution. The crown is the part of the tooth that is visible above the gum line, and it can be covered with a porcelain crown that looks exactly like a tooth in shape and color. After studying your needs, together we can decide on the most satisfactory method to restore your most attractive smile.
