If you’ve ever read online that root canal therapy causes cancer, don’t be alarmed—it doesn’t. What it does do is save a deeply decayed tooth that might otherwise be lost.
Tooth decay is caused by acid produced by bacteria, which dissolves enamel to create a hole or cavity. But it doesn’t stop there: decay can move on to infect the tooth’s innermost layer, the pulp filled with nerves and blood vessels. Unchecked, the resulting infection can travel through the root canals to eventually infect the bone.
A root canal treatment stops the infection before it goes this far. After administering a local anesthetic, we drill a small hole into the tooth to access the pulp chamber and root canals. We then remove all the diseased tissue, disinfect the space and then place a filling within the empty chamber and root canals to prevent further infection. We then seal the access hole and later crown the tooth to further protect and stabilize it.
It’s no exaggeration, then, to say that root canal treatments have saved millions of teeth. So, for all its beneficial effect, why is it considered by some to pose a health danger?
The germ for this notion comes from the early 20th Century when a dentist named Weston Price theorized that leaving a “dead” organ in place would harm the body. Since a root-canaled tooth with the pulp’s living tissue removed is technically no longer viable, it fit the category of “dead” tissue. Thus, according to this theory, maladies like cancer could arise because of the “dead” tooth.
Unfortunately, this theory has found a somewhat new life recently on the internet, even though it was thoroughly investigated and debunked in the 1950s. And as late as 2013, a study published in a journal of the American Medical Association found no increased cancer risk after root canal treatment, and even some evidence for a reduced risk.
So, if your dentist recommends root canal treatment, rest assured it’s needed to save your tooth. Rather than harm your health, it will improve it.

As tough as teeth are, life can take its toll on them and sometimes lead to parts of them chipping off. Although it might not affect a tooth's overall health, it can certainly downgrade its appearance.
But we can restore a chipped tooth like new, and it may not require extensive dental work. Thanks to a versatile dental material called composite resin, we can often bring back a tooth's natural appearance in just one visit.
Tooth-colored resins have been around for decades, but their application has been limited due to issues with durability. Recently developed bonding techniques, though, have made them a workable option for restoring mild to moderate tooth defects.
We do this by applying and bonding the composite resin to a tooth to “fill in” the missing portion. While it's often a short process, it does require a thorough understanding of tooth anatomy, function and aesthetics.
We begin with a comprehensive exam to assess the true condition of a chipped tooth. Some dental defects might be better served with a porcelain restoration like a veneer or crown for best results. Still, there are a wide range of defects for which composite resins is a solid repair choice.
Once we've determined bonding is appropriate, we prepare the tooth by first roughening its outer surface and then etching it with an acid solution to increase bonding strength. We then apply a luting agent, a kind of dental cement, also to aid with bonding.
We then begin applying the composite resin in liquid form, one layer at a time. This layering process helps simulate the color depth and shape of the tooth, and to further incorporate strength into the restoration. We're also careful at this point to match the variations of color with those of the surrounding teeth so that it looks as natural as possible.
As we finish each layer, we apply a curing light to harden the resin. We can then polish the finished product and make adjustments for the bite. The end result is a tooth that not only looks whole, but natural and blended with the rest of your teeth. Bonding could truly change your smile in just one visit.

Your gums play an important role in dental function and health. Not only do they help anchor teeth in the jaw, the gums also protect tooth roots from disease.
But you can lose that protective covering if your gums recede or shrink back from the teeth. An exposed tooth is more susceptible to decay, and more sensitive to temperature and pressure.
Here are 4 causes for gum recession and what you can do about them.
Gum disease. The most common cause for gum recession is a bacterial infection called periodontal (gum) disease that most often arises from plaque, a thin film of bacteria and food particles accumulating on teeth. Gum disease in turn weakens the gums causes them to recede. You can reduce your risk for a gum infection through daily brushing and flossing to remove disease-causing plaque.
Genetics. The thickness of your gum tissues is a genetic trait you inherit from your parents. People born with thinner gums tend to be more susceptible to recession through toothbrush abrasion, wear or injury. If you have thinner tissues, you’ll need to be diligent about oral hygiene and dental visits, and pay close attention to your gum health.
Tooth eruption. Teeth normally erupt from the center of a bony housing that protects the root. If a tooth erupts or moves outside of this housing, it can expose the root and cause little to no gum tissue around the tooth. Moving the tooth orthodontically to its proper position could help thicken gum tissue and make them more resistant to recession.
Aggressive hygiene. While hard scrubbing may work with other cleaning activities, it’s the wrong approach for cleaning teeth. Too much force applied while brushing can eventually result in gum damage that leads to recession and tooth wear. So, “Easy does it”: Let the gentle, mechanical action of the toothbrush bristles and toothpaste abrasives do the work of plaque removal.
While we can often repair gum recession through gum disease treatment or grafting surgery, it’s much better to prevent it from happening. So, be sure you practice daily brushing and flossing with the proper technique to remove disease-causing plaque. And see your dentist regularly for cleanings and checkups to make sure your gums stay healthy.

Every year many parents learn their “tweenager” or teenager needs their bite corrected, often with specialized orthodontics. Imagine, though, if these families could go back in time to when their child’s poor bite was just developing to stop or slow it from forming.
Time travel may still be science fiction, but the approach suggested isn’t. It’s called interceptive orthodontics, a group of techniques and procedures performed during the early stages of jaw development. The focus is usually on getting abnormal jaw growth back on track, enough so that a poor bite won’t form.
The upper jaw, for example, may be growing too narrow, reducing the amount of available space for tooth eruption. If it isn’t corrected, teeth can erupt out of position. To correct it, an orthodontist places a palatal expander in the roof of the child’s mouth (palate). The appliance applies gentle pressure against the inside of the teeth, which stimulates the jaws to develop wider.
The expander works because of a separation in the bones at the center of the palate, which later fuse around puberty. The pressure applied from the expander keeps this gap slightly open; the body then continues to fill the widening expansion with bone, enough over time to widen the jaw. If you wait until puberty, the gap has already fused, and it would have to be reopened surgically to use this technique. Ideally, then, a palatal expander should be employed at a young age.
Not all interceptive techniques are this extensive—some, like a space maintainer, are quite simple. If a primary (baby) tooth is lost prematurely, teeth next to the empty space tend to drift into it and cause the intended permanent tooth to erupt out of place due to a lack of space. To prevent this an orthodontist places a small wire loop within the space to prevent other teeth from moving into it.
These are but two examples of the many methods for stopping or slowing a developing bite problem. To achieve the best outcome, they need to be well-timed. Be sure, then, to have your child undergo an orthodontic evaluation around age 6. If an interceptive orthodontic approach is needed, it could eliminate the need for more extensive—and expensive—treatment later.
While celebrating all that a new year brings, take a moment to remember the New Year's Day birthday of a true American patriot: the legendary Paul Revere. Ironically, he became a legend some 80 years after his midnight trek to warn colonists of approaching British troops, thanks to Henry Wadsworth Longfellow's 1861 poem “Paul Revere's Ride.” He was much better known to his fellow Bostonians as a prosperous silversmith, engraver—and “artificial teeth” maker.
That's right. Among his many business endeavors, Revere's résumé also included dental prosthetics, specifically custom dentures made of ivory. For the time, his work was state-of-the-art technology that far surpassed older tooth replacement methods.
But when we compare Revere's foray into the dental arts and today's restorations, his high quality 18th Century dentures were the proverbial “horse and buggy,” while modern denture technology seems like “supersonic transport.” Not only are today's dentures made of superior materials that are more “toothlike” in appearance, the means to create them using digital technology gives wearers a more secure and comfortable fit.
The modern denture—an appliance that replaces multiple or all lost teeth—is composed of a polymer base, usually acrylic that is colored to resemble gum tissue. Attached to this base are the prosthetic (“false”) teeth that replace those lost along the jaw. These new teeth are usually made of a durable dental material like porcelain that looks and functions like real teeth.
The basic design of today's denture hasn't changed much in the last century. What has changed is our ability to create dentures that follow an individual jaw contours much more precisely. Using the latest digital technology, we're able to obtain highly accurate impressions of the mouth to guide the manufacturing process. Fit is critically important for how dentures feel and function in the mouth. If they are too loose, they become uncomfortable and limit which foods you can eat.
If that weren't enough, recent advancements with dental implants have taken dentures to an entirely new level, beyond anything imaginable in Revere's day. We're now able to create dentures that connect or are permanently affixed to implants set within the jaw, which makes them more stable and secure. An implant-supported denture also helps prevent bone loss, a weakness of traditional dentures, causing them to loosen over time.
As amazing as they are, we wouldn't have the modern version of dentures without craftsmen like Paul Revere who helped advance the cause of dental restoration. So, lift a glass of holiday cheer this season to this hero of the American Revolution—and of American dentistry.
