Most people associate bacteria with disease and ill health. But the real story about the trillions of microscopic organisms now living in and on your body is a bit more complicated. With recent advances in genetic code research scientists are learning that many of these microorganisms you’re hosting are actually beneficial for you — including your teeth and gums.
Beginning at birth and throughout your lifetime you are continually developing a distinct microbiome — actual communities of bacteria and other microorganisms that inhabit your body. As your microbiome develops it helps train your immune system to distinguish between “good” bacteria that help with digestion and other bodily processes and “bad” bacteria that cause disease.Â And it continually adapts to changes in what we eat, the pets we acquire or the drugs we take.
But lifestyle choices like diet can also have a detrimental effect, causing harmful bacteria to become dominant. This seems to be the case with Streptococcus mutans, the bacterial strain most associated with tooth decay. Scientists have analyzed biofilm (plaque deposits on teeth) from the pre-industrial era before 1900 and compared it with modern biofilm samples. They’ve found Streptococcus mutans levels to be much higher in modern biofilm, which they directly attribute to the modern Western diet.
As we gain a better understanding of these findings and of the role of bacteria in our lives, it could change many health recommendations not only about diet but about medications too. In the fight against disease, for example, we’ve used antibiotics to eradicate infection-causing microorganisms, but with a broad destructive ability that can also kill many beneficial strains of bacteria. It’s hoped as our knowledge grows we’ll be able to create newer drugs that more narrowly target harmful microorganisms while not affecting beneficial ones.
There’s a new appreciation emerging for bacteria’s role in our lives. As a result efforts to rebalance a person’s microbiome when they become sick may eventually become a critical element in healthcare treatment strategies. The benefits of this strategy for health, including for our teeth and gums, could be quite impressive.

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.
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.
