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.

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.
