With exciting innovations in cosmetic dentistry over the last few decades, we can now transform nearly any unattractive smile. One of the best and most cost-effective of these is the porcelain veneer. These thin layers of dental porcelain are bonded over the front of chipped, slightly misaligned or stained teeth to create an entirely new look.
Veneers have evolved over time, especially with the materials they contain that give them their beauty and life-likeness. The first veneers were made mainly of feldspathic porcelain, a mineral composition known for its similarity in color and translucence to natural teeth.
But because this early porcelain had a high amount of silica (in essence, glass), and because they were created through overlaying several thin layers that weren’t as strong as a single piece, they were prone to shattering. This made them problematic for teeth subject to heavy biting forces or patients with clenching or grinding habits.
The situation changed dramatically in the 1990s, when dental labs began adding Leucite, a sturdier glass-like mineral that didn’t diminish the porcelain’s translucence. Not only did Leucite make veneers more shatter-resistant, it also enabled dental technicians to fashion most of the veneer in one piece to further strengthen it.
More recent veneers may now incorporate an even stronger material called lithium disilicate. Because lithium disilicate has twice the strength of Leucite, veneers made with it can be as thin as 0.3 millimeters. Not only does this blend together the most desirable qualities expected of a veneer—strength, aesthetic appeal and easy fabrication—it allows for a broader range of situations and uses.
Both of these materials can be pressed or milled to assume the exact shape necessary to fit a particular tooth. The manufacturing process also allows for creating smaller veneers that can then be overlaid with porcelain for the most life-like appearance possible.
Thanks to these stronger materials enhancing the natural beauty of porcelain, we now have a wider creative palate for transforming your smile.

Porcelain veneers are one of the best ways to transform your teeth’s appearance with only a small amount of tooth preparation. But even that small amount could leave a veneered tooth permanently altered.
As the name implies, veneers are thin layers of custom-designed porcelain bonded to the outside of a tooth to cover defects. They’re usually ideal for minor chipping, staining or even slight tooth misalignments. But although they’re thin—often just a millimeter or so in thickness—they can still make a tooth appear or feel bulky.
To reduce this extra width, we usually need to remove some of the tooth’s surface enamel. Since enamel doesn’t replenish itself, this alteration could mean the tooth will require a restoration from then on.
But now, you may be able to take advantage of new advances in this popular restoration: No-Prep or Minimal Prep veneers that involve little to no tooth alteration. In most cases they’re simply bonded to the teeth with only slight enamel reshaping.
Because of their ultra-thinness, No-Prep veneers (usually between 0.3 to 0.5 mm, as thin as a contact lens) are bonded directly to teeth that are practically untouched beforehand. A Minimal Prep veneer usually requires only enamel reshaping with an abrasive tool before it’s placed. And unlike traditional veneers, they can often be removed if needed to return the teeth to their original form without another restoration.
These new veneers are best for people with small teeth, often from wear due to teeth grinding, narrow smiles (the side teeth aren’t visible while smiling), or slightly misshapen teeth like underdeveloped teeth that can appear peg-shaped. But people with oversized teeth, some malocclusions (bad bites) or similar dental situations may still require enamel removal to avoid bulkiness even with ultra-thin veneers.
If you don’t have those kinds of issues and your teeth are reasonably healthy, we can apply No-Prep or Minimal Prep veneers in as few as two appointments. The result could be life-changing as you gain a new smile you’re more than happy to share.

Porcelain veneers are positive proof that unattractive teeth don't always require an intensive restoration to regain their beauty. These thin layers of translucent porcelain — custom-designed and color-matched to blend with your other teeth — are permanently bonded to the visible side of your front teeth.
Although they can't remedy every tooth defect, they're well suited for mild to moderate disfigurements like chipping, staining or gaps. There are now two types of porcelain veneers: the traditional veneer and the “no-prep” veneer.
The standard veneers require some tooth structure removal, referred to as “tooth preparation.” This is because although they're a millimeter or less in thickness, they can still appear bulky if bonded to an unprepared tooth. To accommodate their width, it's necessary to remove some of the tooth enamel. This permanently alters the tooth so that it will need some form of restoration from that time on.
In recent years, however, other veneer options have emerged that reduces — or even eliminates — this tooth alteration. No-prep veneers are so thin they can be applied to a tooth with virtually no preparation. A more common option, minimal-prep, requires only a minor reshaping with an abrasive tool to ensure the fitted veneer looks as natural as possible. Because of their thinness, these veneers also don't have to fit under the gum line like standard veneers.
To obtain no- or minimal-prep veneers, your tooth enamel needs to be in good, healthy shape. They're also best suited for people with small or worn teeth, narrow smiles (the side teeth can't be seen from the front), or slightly stained or misshapen teeth.
Because there's little invasiveness, these low preparation veneers won't typically create tooth sensitivity and they can often be applied without any form of anesthesia. And because tooth structure isn't removed, they can be “uninstalled” to return to your natural look. Of course, that's not always an easy process since the bonding between veneer and the enamel is quite strong, although today's lasers can be used to detach the veneer quite easily.
If you'd like to consider these minimally invasive veneers, talk with your dentist. If you're a good candidate, you may be able to gain a new smile without much change to your natural teeth.

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.
