Want to know the exact wrong way to pry open a stubborn lid? Just ask Jimmy Fallon, host of NBC-TV’s popular “Tonight Show.” When the 40-year-old funnyman had trouble opening a tube of scar tissue repair gel with his hands, he decided to try using his teeth.
What happened next wasn’t funny: Attempting to remove the cap, Fallon chipped his front tooth, adding another medical problem to the serious finger injury he suffered a few weeks before (the same wound he was trying to take care of with the gel). If there’s a moral to this story, it might be this: Use the right tool for the job… and that tool isn’t your teeth!
Yet Fallon is hardly alone in his dilemma. According to the American Association of Endodontists, chipped teeth account for the majority of dental injuries. Fortunately, modern dentistry offers a number of great ways to restore damaged teeth.
If the chip is relatively small, it’s often possible to fix it with cosmetic bonding. In this procedure, tough, natural-looking resin is used to fill in the part of the tooth that has been lost. Built up layer by layer, the composite resin is cured with a special light until it’s hard, shiny… and difficult to tell from your natural teeth. Best of all, cosmetic bonding can often be done in one office visit, with little or no discomfort. It can last for up to ten years, so it’s great for kids who may be getting more permanent repairs later.
For larger chips or cracks, veneers or crowns may be suggested. Veneers are wafer-thin porcelain coverings that go over the entire front surface of one or more teeth. They can be used to repair minor to moderate defects, such as chips, discolorations, or spacing irregularities. They can also give you the “Hollywood white” smile you’ve seen on many celebrities.
Veneers are generally custom-made in a lab, and require more than one office visit. Because a small amount of tooth structure must be removed in order to put them in place, veneers are considered an irreversible treatment. But durable and long-lasting veneers are the restorations of choice for many people.
Crowns (also called caps) are used when even more of the tooth structure is missing. They can replace the entire visible part of the tooth, as long as the tooth’s roots remain viable. Crowns, like veneers, are custom-fabricated to match your teeth in size, shape and color; they are generally made in a dental lab and require more than one office visit. However, teeth restored with crowns function well, look natural, and can last for many years.
So what happened to Jimmy Fallon? We aren’t sure which restoration he received… but we do know that he was back on TV the same night, flashing a big smile.

Porcelain veneers are a great way to enhance an unattractive smile. But are they appropriate for teenagers? The answer usually depends on a patient’s current development stage and the type of veneer used.
Veneers are thin layers of porcelain bonded to the front of teeth. But even though quite thin, they can appear bulky if we don’t first remove some of the tooth’s enamel surface. This is irreversible, so the tooth may require a restoration from then on.
This could be a major issue for teens whose permanent teeth are still developing. During this period the tooth’s central pulp is relatively large and the dentin layer not fully developed. As a result, the pulp’s nerves are often closer to the surface than in an adult tooth. This increases risk of nerve damage during veneer preparation; if nerve damage occurs, the tooth could ultimately require a root canal treatment to save it.
On the other hand, some types of veneers don’t require tooth alteration (or only very little) beforehand. These “no-prep” or “minimal prep” veneers are best for certain situations like abnormally small teeth, so we must first determine if using such a veneer would be appropriate for your teen.
In effect, we’ll need to weigh these and other factors before determining if veneers are a safe choice for your teen. That being the case, it may be more advisable to consider more conservative cosmetic techniques first. For example, if enamel staining is the main issue, you could consider teeth whitening. Although the often amazing results eventually fade, whitening could still buy some time until the teeth have matured to safely apply veneers.
Slight deformities like chipping can often be corrected by bonding tooth-colored composite material to the tooth. In artistic hands it’s even possible to create a full veneer effect with very little if any tooth preparation. How much we can apply, though, depends on tooth size, and it won’t be as durable as a porcelain veneer.
With that said, veneers could be the right solution to enhance your teen’s smile. But, we’ll need to carefully consider their dental situation to ensure their new smile remains a healthy one.
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.
