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.

The March 27th game started off pretty well for NBA star Kevin Love. His team, the Cleveland Cavaliers, were coming off a 5-game winning streak as they faced the Miami Heat that night. Less than two minutes into the contest, Love charged in for a shot on Heat center Jordan Mickey—but instead of a basket, he got an elbow in the face that sent him to the floor (and out of the game) with an injury to his mouth.
In pictures from the aftermath, Love’s front tooth seemed clearly out of position. According to the Cavs’ official statement, “Love suffered a front tooth subluxation.” But what exactly does that mean, and how serious is his injury?
The dental term “subluxation” refers to one specific type of luxation injury—a situation where a tooth has become loosened or displaced from its proper location. A subluxation is an injury to tooth-supporting structures such as the periodontal ligament: a stretchy network of fibrous tissue that keeps the tooth in its socket. The affected tooth becomes abnormally loose, but as long as the nerves inside the tooth and the underlying bone have not been damaged, it generally has a favorable prognosis.
Treatment of a subluxation injury may involve correcting the tooth’s position immediately and/or stabilizing the tooth—often by temporarily splinting (joining) it to adjacent teeth—and maintaining a soft diet for a few weeks. This gives the injured tissues a chance to heal and helps the ligament regain proper attachment to the tooth. The condition of tooth’s pulp (soft inner tissue) must also be closely monitored; if it becomes infected, root canal treatment may be needed to preserve the tooth.
So while Kevin Love’s dental dilemma might have looked scary in the pictures, with proper care he has a good chance of keeping the tooth. Significantly, Love acknowledged on Twitter that the damage “…could have been so much worse if I wasn’t protected with [a] mouthguard.”
Love’s injury reminds us that whether they’re played at a big arena, a high school gym or an outdoor court, sports like basketball (as well as baseball, football and many others) have a high potential for facial injuries. That’s why all players should wear a mouthguard whenever they’re in the game. Custom-made mouthguards, available for a reasonable cost at the dental office, are the most comfortable to wear, and offer protection that’s superior to the kind available at big-box retailers.

While the term “plastic surgery” might bring to mind face lifts or tummy tucks, not all procedures in this particular surgical field are strictly cosmetic. Some can make a big difference in a person’s health.
One example is periodontal plastic surgery, which corrects gum tissue loss around the teeth. Although these procedures can indeed improve appearance, they more importantly help save teeth.
Gum loss is most often a consequence of periodontal (gum) disease, a bacterial infection arising from a thin film of food particles on the teeth called dental plaque. As the disease weakens the gums’ attachment to teeth, they shrink back or recede, exposing the area around the roots. Without the protective cover the gums provide the roots, they become more susceptible to decay.
In milder cases of gum recession, treating the infection often results in the gums regaining their normal attachment to teeth. But with more advanced recession, natural gum healing may not be enough to reverse it. For such situations grafting donor tissue to the recessed area can help stimulate new tissue growth.
While gum tissue grafts can come from an animal or other human, the most likely source is from the person themselves. In one type of procedure, free gingival grafting, the surgeon locates and completely removes (or “frees”) a thin layer of skin resembling gum tissue, typically from the roof of the mouth, shapes it and then transplants it by suturing it to the recession site. Both donor and recipient sites heal at about the same rate in two to three weeks.
Another technique is known as connective tissue grafting. In this procedure the surgeon partially removes the donor tissue from its site while leaving a portion containing blood vessels intact. The palatal tissue is still used and transported to fit beneath the tissue that’s still attached to the blood supply. This connective tissue graft is then positioned and sutured to the recipient site while still maintaining its blood supply connection at the donor site. Maintaining this connection facilitates healing and increases the chances the graft will “take” and become firmly attached to the new site.
Grafting procedures require advanced techniques and skills. But with them we may be able to restore gum attachment to teeth with an impact on appearance and dental health that’s well worth the effort.

Nothing grabs your attention like a sharp tooth pain, seemingly hitting you out of nowhere while you’re eating or drinking. But there is a reason for your sudden agony and the sooner you find it out, the better the outcome for your oral health.
To understand tooth sensitivity, we need to first look at the three layers of tooth anatomy. In the center is the pulp filled with blood vessels and nerve bundles: it’s completely covered by the next layer dentin, a soft tissue filled with microscopic tubules that transmit sensations like pressure or temperature to the pulp nerves.
The third layer is enamel, which completely covers the crown, the visible part of a tooth. Enamel protects the two innermost tooth layers from disease and also helps muffle sensations so the tooth’s nerves aren’t overwhelmed. The enamel stops at about the gum line; below it the gums provide similar protection and sensation shielding to the dentin of the tooth roots.
Problems occur, though, when the dentin below the gums becomes exposed, most commonly because of periodontal (gum) disease. This bacterial infection caused by dental plaque triggers inflammation, which over time can weaken gum tissues and cause them to detach and shrink back (or recede) from the teeth. This can leave the root area vulnerable to disease and the full brunt of environmental sensations that then travel to the nerves in the pulp.
Tooth decay can also create conditions that cause sensitivity. Decay begins when certain oral bacteria multiply and produce higher than normal levels of acid. The acid in turn dissolves the enamel’s mineral content to create holes (cavities) that expose the dentin. Not treated, the infection can eventually invade the pulp, putting the tooth in danger of being lost unless a root canal treatment is performed to remove the infection and seal the tooth from further infection.
So, if you begin experiencing a jolt of pain while eating or drinking hot or cold foods or beverages, see your dentist as soon as possible to diagnose and treat the underlying cause. And protect your teeth from dental disease by practicing daily brushing and flossing, as well as seeing your dentist for regular dental cleanings and checkups. Don’t ignore those sharp pains—your teeth may be trying to tell you something.

What does November make you think of? Pumpkins? Turkeys? Dry leaves and frosty mornings? How about cigarette butts?
If you’re wondering about the last item, remember that November 15 is the date of the Great American Smokeout—a day set aside for those who want to take the first steps toward quitting the tobacco habit. While the percentage of smokers in the U.S. has dropped to less than 16% in recent years, according to the American Cancer Society there are still some 38 million Americans who smoke cigarettes. Smoking causes over 480,000 deaths every year, and is the leading preventable cause of death in the U.S.
Even if it doesn’t kill you, the effects of tobacco use can be devastating to your entire body—including your mouth. Whether you smoke cigarettes or use chewing tobacco, your risk of oral cancer is greatly increased, as is your chance of developing periodontal (gum) disease. What’s more, smoking can mask the symptoms of gum disease, so your condition is actually worse than it appears. Severe gum disease is one reason why smokers tend to lose more teeth than non-smokers.
In addition, because smoking interferes with the natural healing process, smokers have a much greater chance of dental implant failure. Tobacco use also can lead to increased amounts of plaque, which results in tooth decay and other oral health problems. It also stains your teeth, reduces your senses of smell and taste, and gives you bad breath.
Ready to quit yet? If so, there are lots of resources to help you on the road to a healthier life. The American Cancer Society, sponsor of the Smokeout, can help you make a plan to quit tobacco—and stay off it. It’s not easy, but over a million Americans do it every year. See their website for more information, plans and tips on quitting. Your health care professionals are also a great source of information and help when it’s time to get off the tobacco habit. Feel free to ask us any questions you may have.
And here’s the good news: The moment you quit, your body begins to recover from the effects of tobacco use. In just one year, you’ll have cut your risk of heart attack and stroke in half. After 5 to 15 years, your risk of stroke, coronary heart disease, and several other conditions is the same as someone who has never smoked.
