Dental veneers are a popular way to improve teeth with chips, stains, gaps or other defects. They're typically made of dental porcelain, ceramic-like materials prized for their ability to mimic the texture, color and translucency of natural teeth.
But dental porcelain doesn't come in one form—a dentist can utilize variations of it to better match a patient's need. For example, one patient may need a porcelain with added strength, while another may need one that provides better coverage of underlying discoloration.
The foundational materials for veneer porcelain are glass ceramics. Also used for crowns, glass ceramics have been the preferred choice of dentists for some time to achieve life-like results. In terms of veneers, dental technicians first mix the powdered form of the porcelain with water to create a paste. They then use the paste to build up the body of a veneer layer by layer.
But while the high degree of silica (glass) in this type of porcelain best resembles the translucence of natural teeth, early forms of it lacked strength. This changed in the 1990s when technicians began adding a material called leucite to the ceramic mixture that enhanced its strength and durability.
Today, you'll also find lithium disilicate used, which is twice as strong as leucite and is quite useful when creating thinner veneers. Both of these strength materials can be pressed and milled into shape, which helps achieve a more accurate fit. Along with the underlying glass ceramic, the result is a veneer that's both durable and incredibly life-like.
Although today's porcelain veneers are far superior in durability than earlier forms, they can be damaged when biting down on hard objects. To make sure your veneers last as long as possible, you should avoid biting down directly on hard-skinned fruit, or using your veneered teeth to crack nuts or crunch ice (or any other teeth, for that matter).
But with proper care, today's veneers have exceptional longevity. And, thanks to the superior dental materials that compose them, they'll look great for years.

Although we've known for some time how tooth decay forms, it's still prevalent across the population—even more so than cancer or heart disease. Along with gum disease, it's a leading cause of tooth loss.
Fortunately, our knowledge about tooth decay has grown considerably, to the point that we now recognize a number of risk factors that make it more likely a person will develop this disease. By first identifying them in individual patients, we can take steps to address them specifically to reduce the chances of this destructive disease.
Genetics. Researchers have identified around 40 to 50 genes that can influence cavity development. The best way to assess your genetic risk is through family history—if numerous close family members contend with tooth decay, your risk may be high. If so, it's important to be extra vigilant with addressing other areas over which you have more control.
Saliva. Cavities are directly caused by oral acid, a byproduct of bacteria, that can erode tooth enamel over prolonged contact. This is minimized, though, through a normal saliva flow that neutralizes acid and helps remineralize enamel. But poor saliva production can slow acid neutralization. You can improve your saliva flow by drinking more water, changing medications or using saliva-boosting products.
Oral hygiene. You can reduce bacteria (and thus acid) by removing their "room and board"—dental plaque. This accumulating film of food particles harbors the bacteria that feed on it. Daily brushing and flossing, accompanied by regular dental cleanings, effectively removes dental plaque, which in turn lowers the levels of oral bacteria and acid.
Dental-friendly diet. Even if you diligently address the previous risk factors, your diet may fight against your efforts. Diets high in processed and refined foods, especially sugar, provide abundant food sources for bacteria. On the other hand, a diet primarily of whole foods rich in vitamins (especially D) and minerals like calcium and phosphorous strengthen teeth against decay.
Preventing tooth decay isn't a "one-size-fits-all" approach. By identifying your own particular risk, we can craft a care strategy that can be your best defense against this destructive dental disease.
First, there were braces; then came removable clear aligners—both great ways to straighten teeth. But braces with their metal brackets and wires aren't the most attractive look. And, although nearly invisible aligners improve appearance, they don't work in every bite situation (although their range has improved of late).
But now a third choice has emerged: lingual braces. Like their traditional counterparts, lingual braces are fixed in place—but on the back side of the teeth rather than the front. Instead of "pushing" teeth toward new positions, they "pull" them, arriving at the same "destination" by another path.
This new method came about simultaneously by two different orthodontists a world apart and for different reasons. A Beverly Hills dentist was looking for an invisible form of treatment similar to clear aligners for his appearance-conscious patients. A Japanese dentist wanted an alternative that would reduce the risk of damage or injury posed by traditional braces to his martial arts patients.
Lingual braces (referring to their proximity to the tongue) address both of these concerns. All of the brackets and wiring are positioned out of sight. And because they're shielded by the teeth, they're not as likely to be damaged or cause injury following hard contact to the face—a great benefit for athletes, law enforcement officers and, yes, martial artists.
Even so, lingual braces won't replace the other two methods any time soon. You'll need to consider other factors, such as that lingual braces can cost up to a third more than traditional braces. And although their availability is steadily growing, not all orthodontists have been trained to offer lingual braces, so you may have to widen your search radius for a provider near you.
You may also find it takes a bit of time to get used to the feel of lingual braces. Upper braces can affect speech ability, at least initially, and the lower ones can interfere with tongue comfort. Most people, though, do adjust to them within a week or so.
But by and large, lingual braces do offer a fixed option that's out of sight, out of mind. With this newer orthodontic choice, you now have three good options for achieving a healthier mouth and a more attractive smile.
