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 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.
If you’re committed to providing your family nutritional, low-sugar snacks, you’re not only helping their physical well-being but their dental health too. If you have school-age children, though, you might be concerned about other snacks available to them while away from home.
To begin with, any potential problems at school with available snack items might not be as bad as you think. A few years ago the U.S. Department of Agriculture (USDA) established new snacking guidelines for public schools. Known as the Smart Snacks in Schools initiative, the new guidelines require schools to only allow snacks sold on school grounds that meet minimum nutritional standards. In addition, these guidelines promote whole grains, fruits, vegetables and low-fat dairy products.
Still, the guideline standards are only a minimum, which could leave plenty of room for snacks that don’t meet your nutritional expectations. And school-offered snacks aren’t the only ones available on campus: there are also those brought by other students, which often get swapped around. The latter represent tempting opportunities for your child to consume snacks that aren’t the best for dental health.
But there are things you can do to minimize the lure of these poor snacking opportunities at school. First and foremost is to educate your child on why some snacks are better for them than others. In other words, make nutrition an instilled family value—and, of course, practice what you preach.
You can also send them with snacks you deem better for them than what’s available at school. Of course, you’ll be competing with a lot of exciting and enticing snacks, so try to inject a little “pizzazz” into yours like a dusting of cinnamon or a little parmesan cheese on popcorn. And use a little creativity (even getting your kids involved) to make snack choices fun, like using cookie-cutters to shape whole-grain bread and cheese into shapes.
And consider getting involved with other parents to encourage school administrators to adopt stricter snack standards over and above the Smart Snacks in Schools initiative. This not only may improve the nutritional content of available snacks, but also transform a “family value” into a community-wide appreciation for snacks that promote healthy teeth and gums.
