Root canal treatment can be an effective life preserver for a heavily decayed tooth. The question a lot of people ask, though, is how long might the tooth survive after treatment.
That’s an important concern since the treated tooth was in dire straits beforehand as decay had infected its inner most layer, the pulp. The infection, which had caused the living bundles of nerves, blood vessels and connective tissue within to become inflamed and diseased, was poised to invade even deeper through the root canals. During the root canal treatment, the infected pulp tissue is removed and the empty chamber and root canals are filled with a special filling to seal the tooth from further infection.
The protection, though, isn’t an absolute certainty: how long a treated tooth survives depends on a number of factors. For one, the earlier a diseased tooth can be initially diagnosed — especially if the infection hasn’t spread into the jawbone — the better the procedural outcome. Likewise, the chances of longevity are also better if the initial root canal treatment was thorough in identifying and filling all the root canals as well as capping the tooth with a life-like crown in a timely manner after treatment.
The type and location of the tooth can also affect its long-term health. Front teeth, with their single roots and canals are easier to access and treat. Back teeth, by contrast, can have two or more roots and a more intricate canal network. These kinds of complications could require the use of special microscopic equipment and the expertise of an endodontist, a specialist in root canals.
Even if a re-infection occurs, the tooth isn’t necessarily lost. A repeat root canal treatment that addresses these and other issues, could give the tooth a “third” chance. In any case, if a tooth is worth saving attempting a root canal treatment is generally preferable to losing the tooth and replacing it with a prosthetic tooth — it’s well worth the try.

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.
