With smart phone in hand, you can instantaneously find out just about anything. Unfortunately, online search results aren’t always accurate. Case in point: there’s an idea floating on the World Wide Web that root canal treatments cause cancer.
Sounds ludicrous? Yes, but like other strange ideas this one has historical roots (pardon the pun). In the early 20th Century, a dentist named Weston Price propagated the idea that leaving a “dead” organ in the body caused health problems. By his view, a root canal-treated tooth fell into this category and could potentially cause, among other things, cancer.
But concern over root canal treatment safety is on shaky ground: dentistry examined Dr. Price’s ideas over sixty years ago and found them wanting. But first, let’s look at what a root canal treatment can actually do for your health.
Tooth decay is an infection that first attacks the outer tooth enamel and then continues to advance until it infects the inner pulp. It can then travel through the root canals to the roots and bone. Without intervention, the infection will result in tooth loss.
We use a root canal treatment to save the tooth from this fate. During the procedure we remove and disinfect all of the diseased or dead tissue within the pulp and root canals. We then fill the empty chamber and canals with a special filling and seal the tooth to prevent any further infection. And while technically the procedure renders a tooth unable to respond to thermal sensitivity or tooth decay, the tooth is still alive as it is attached to the periodontal ligament and its blood supply and nerve tissue. The tooth can still “feel” if you bite on something too hard and it doesn’t affect the tooth’s function or health, or a patient’s overall health for that matter.
As to Dr. Price’s theory, extensive studies beginning in the 1950s have examined the potential health risk of root canal treatments. The latest, a 2013 patient survey study published in a journal of the American Medical Association, not only found no evidence linking root canal treatment to cancer, but a lower risk of oral cancer in 45% of patients who had undergone multiple root canal treatments.
While root canal treatments do have potential side effects, none are remotely as serious as this online “factoid” about cancer. It’s far more likely to benefit your health by saving your tooth.

When it comes to replacing a missing tooth, you have several options, including a removable partial denture or a fixed bridge. But the premier choice is “the new kid on the block” at just over thirty years old: dental implants. Implants are by far the most popular tooth replacement choice among both patients and dentists.
But they also happen to be the most expensive option, at least initially. So the question is, why invest in dental implants over less costly choices?
Here are 3 reasons why implants could be well worth their price.
More Like a real tooth than other restorations. Implants can match the life-like appearance of any other replacement choice, often utilizing the same types of materials. But where they really excel is in function—how they perform while biting and chewing. This is because the dental implant’s titanium post imbedded in the jawbone replaces the tooth root. No other dental restoration can do that—or perform better when comparing the resulting functionality.
Best long-term solution. As we mentioned before, the initial implant cost is typically higher than either dentures or bridges. But you should also consider their durability compared to other choices. It could be potentially much longer—possibly decades. This is because the titanium post creates an ultra-strong hold in the jawbone as bone cells naturally grow and adhere to this particular metal. The resulting hold can withstand the daily forces generated during eating and chewing. With proper care they might even last a lifetime, and actually cost you less in the long run over other choices.
Adaptable to other types of restoration. Implants have greater uses other than as individual tooth replacements. A few strategically placed implants can also be used to support removable dentures or a fixed bridge for multiple teeth or an entire dental arch. As the technology continues to advance, implants are helping to make other restoration options stronger, more stable and longer lasting—and adding more value to your investment.

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.
For over a hundred years dental amalgam — a combination of silver, mercury, tin and other metals — has been an effective filling material for teeth damaged by decay. But it has one major drawback — its metallic appearance stands out in stark contrast to the natural color of teeth.
As an alternative, composite resin fillings can match the color, shape and texture of natural teeth. These materials and the techniques used to bond them are proving just as effective as and more aesthetically pleasing than dental amalgam.
Fillings help protect and preserve a decayed tooth. By first removing decayed tooth structure through drilling, the resulting void is filled with durable material that strengthens the tooth and provides it protection from further decay.
The ultimate goal for restoration is to return the tooth to as near normal form and function as possible. Dental amalgam serves well in terms of function, providing the tooth strength in the face of the daily biting forces it encounters. In contrast, composite resins excel in appearance, but haven’t always matched the durability of amalgam. They’re material construction has improved over time, though, as well as the techniques used to bond them to teeth.
Most of these bonding techniques incorporate layering. The first step is to seal the dentin (the porous, living tissue just below the enamel); we then build up the composite material layer by layer within the tooth using special bonding adhesive and curing lights. In some cases where a large volume of tooth structure must be replaced, the restoration is first formed on the tooth and then removed for curing before being cemented into the tooth or a separate restoration is formed by a dental lab.
The end result is a tooth which both looks and functions like a fully intact tooth. Though care must be taken not to subject composite resin restorations to undue forces (no cracking open nutshells, for example), your new filling should continue to serve you and look great for a long time to come.

If you’re considering a dental implant as a replacement for a lost tooth, you’re looking at a restoration method with an amazing 95% success rate after ten years. But that being said there’s still a risk, albeit quite low, the implant might fail.
And if you smoke, the risk is slightly higher. In a recent study of implant patients, twice as many of the failures occurred in smokers compared to non-smokers. If you’re a smoker, you can increase your chances of a successful outcome if you quit the habit.
Nicotine, a chemical within tobacco, is the primary cause for this higher risk. Besides its effect on the pleasure centers of the brain, nicotine also restricts smaller blood vessels that are abundant in the mouth and skin, causing less blood flow. As a result, the mouth doesn’t have as many antibodies and other substances available to fight infection and help traumatized tissues heal.
Because of this, as well as reduced saliva flow due to the habit, smokers have an increased risk of dental disease and are slower to respond to treatment. This can be especially problematic if the gum tissues around an implant become infected, which could lead to a catastrophic failure. Slower healing also impacts the post-surgery period when bone cells in the jaw are growing and adhering to the implant surface, forming a stronger bond.
To avoid these potential risks you should stop smoking before you undergo implant surgery. If you can’t completely kick the habit, you should at least stop a week before surgery and for two weeks after. It’s also critical that you practice good oral hygiene — both brushing and flossing — to minimize the occurrence of dental disease and see us for regular checkups and maintenance appointments.
Taking these steps will greatly increase your chances of being in the vast majority of people who continue to enjoy success with their implants for many years.
