Every year U.S. dentists perform around 25 million root canal treatments and save countless teeth from the ravages of decay. But if you search "root canal" on the Internet, you might encounter an unsettling charge against this tooth-saving treatment—that it causes cancer.
Root canal treatments are routinely used when tooth decay has infected the pulp, the innermost layer of a tooth. During the procedure, we access the pulp and remove all the infected tissue. We then fill the empty pulp and root canals, seal the access hole and later crown the tooth to prevent further infection. Without this intervention, the decay can continue to advance toward the roots and supporting bone, putting the tooth in imminent danger of loss.
So, is there any credibility to this claim that root canal treatments cause cancer? In a word, no: there's no evidence of any connection between root canal treatments and cancer—or any other disease for that matter. On the contrary: root canals stop disease.
As with other types of urban legends and internet hype, the root canal-cancer connection may have arisen from another discredited idea from the early 20th Century. A dentist named Weston Price promoted the notion that leaving a "dead" organ in the body led to health problems. From his perspective, a root canaled tooth with its removed pulp tissue fit this criterion.
In the mid-1950s, dentistry thoroughly examined Dr. Weston's theory pertaining to treatments like root canals. The Journal of the American Dental Association devoted an entire issue to it and found after rigorous scientific inquiry that the theory had no validity in this regard. Another study in 2013 confirmed those findings. In fact, the later study instead found that patients who underwent a root canal treatment had a 45 percent reduction in oral cancer risk.
Given the freewheeling nature of the Internet, it's best to speak with a dental professional about your oral health before trusting a post or article you've found online. Not only are they more informed than an unverified online source, they would certainly not knowingly subject you to a procedure to save a tooth at the expense of your health.

Besides their life-likeness, implants are also prized for their high success rate. More than ninety-five percent of implants continue to function effectively after ten years.
Implants’ advanced technology explains some of their reliability and longevity—they’re as close to natural teeth as we’re now able to achieve. But their impressive success rate also owes to the detailed protocols that dentists follow to install them. One critical part of these protocols is ensuring a patient has enough bone in their jaw to support and precisely situate the implant for the best functional and aesthetic outcome.
Unfortunately, there are situations where a patient doesn’t have enough bone to achieve a satisfactory result. This often happens if there’s been months or years between losing the tooth and considering an implant. The reason why relates to the nature of bone as living tissue.
Like other cellular tissues in the body, bone has a life cycle: Older, worn-out cells die and are absorbed by the body, and new cells form to replace them. The growth cycle in the jaw receives stimulation from the forces generated when we chew, which travel up through the teeth to the bone.
However, this stimulation stops after tooth loss for the related area of bone, which can slow new bone growth. Over time, the volume and density of the bone around a missing tooth gradually decreases, enough eventually to make an implant impractical.
Insufficient bone volume, though, doesn’t necessarily mean an implant is out of the question. We may be able to address the problem by attempting to regenerate the bone through grafting. This is a procedure in which we insert graft material into the affected area of the jawbone. The graft then becomes a scaffold upon which bone cells can grow. After several months, we may have enough regenerated bone to support an implant.
If there’s been too much bone loss, we may still need to consider another form of restoration. But if we can successfully build up the bone around your missing tooth, this premier restoration for replacing lost teeth could become a reality for you.
Sometimes you need only a single solution to improve your smile: teeth whitening to brighten stained teeth; porcelain veneers or crowns to mask dental flaws; or a life-like dental implant to replace a missing tooth. But not all dental situations are that simple and sometimes require a combination of treatments.
A case in point: restoring a missing tooth within a poor bite. The absent tooth itself may be the cause of the bite problem if it’s been missing for some time: The nearby teeth tend to move or “drift” into the empty space, leaving no room for implant placement.
When this happens, you’ll first need orthodontic treatment to correct the bite problem. Not only will this open the space for the implant, it also comes with its own benefits. It obviously improves your smile appearance—but straighter teeth are also easier to keep clean of bacterial plaque, which reduces your disease risk. You may also experience better digestion after your teeth are properly aligned and able to function as they should during eating.
The traditional way to improve a bite is through metal braces. But there are some downsides: For one, braces can make it difficult to keep teeth adequately clean, making wearers more susceptible to tooth decay and gum disease. Braces are also quite visible and can detract from a person’s appearance (even more so if a missing tooth is involved).
Unless your situation requires braces, you can choose clear aligners as an alternative. These clear, computer-generated plastic trays are worn in sequence to gradually move teeth to their desired positions. Unlike braces, you can remove aligners for eating, cleaning or rare special occasions. And, they’re barely noticeable to others.
If you also have a missing tooth, you can have a temporary prosthetic (“false”) tooth built into your aligner trays. In this way you can still enhance your smile while undergoing aligner treatment.
Once your bite has been corrected, we can then proceed with restoring your missing tooth permanently with a dental implant. Although orthodontics adds to the time and expense of restoration, its often necessary to achieve the best result. Your future smile will be the better for it.
How many actresses have portrayed a neuroscientist on a wildly successful TV comedy while actually holding an advanced degree in neuroscience? As far as we know, exactly one: Mayim Bialik, who plays the lovably geeky Amy Farrah Fowler on CBS' The Big Bang Theory… and earned her PhD from UCLA.
Acknowledging her nerdy side, Bialik recently told Dear Doctor magazine, “I'm different, and I can't not be different.” Yet when it comes to her family's oral health, she wants the same things we all want: good checkups and great-looking smiles. “We're big on teeth and oral care,” she said. “Flossing is really a pleasure in our house.”
How does she get her two young sons to do it?
Bialik uses convenient pre-loaded floss holders that come complete with floss and a handle. “I just keep them in a little glass right next to the toothbrushes so they're open, no one has to reach, they're just right there,” she said. “It's really become such a routine, I don't even have to ask them anymore.”
As many parents have discovered, establishing healthy routines is one of the best things you can do to maintain your family's oral health. Here are some other oral hygiene tips you can try at home:
Brush to the music — Plenty of pop songs are about two minutes long… and that's the length of time you should brush your teeth. If brushing in silence gets boring, add a soundtrack. When the music's over — you're done!
Flossing can be fun — If standard dental floss doesn't appeal, there are many different styles of floss holders, from functional ones to cartoon characters… even some with a martial-arts theme! Find the one that your kids like best, and encourage them to use it.
The eyes don't lie — To show your kids how well (or not) they are cleaning their teeth, try using an over-the-counter disclosing solution. This harmless product will temporarily stain any plaque or debris that got left behind after brushing, so they can immediately see where they missed, and how to improve their hygiene technique — which will lead to better health.
Have regular dental exams & cleanings — When kids see you're enthusiastic about going to the dental office, it helps them feel the same way… and afterward, you can point out how great it feels to have a clean, sparkling smile.
Getting a new smile doesn’t have to be an elaborate affair. If your teeth have minor to moderate chips, stains or tooth gaps, dental veneers could be the answer. These thin wafers of dental porcelain mask tooth imperfections and completely change your smile’s dynamic—and without a huge impact to your wallet.
To achieve that effect, though, your personal set of veneers will require the expertise of both your dentist and a dental lab technician to design and create your veneers. And while there are numerous considerations in achieving a truly life-like appearance with veneers, one of the most important is their color.
We always associate the color white with teeth. And while it is the dominant hue, actual tooth color is more complex. An individual tooth is comprised of multiple shades and tints, that range in variation from its biting edge to the gums. Likewise, tooth color in general can differ from person to person.
Your dentist must take these individual color variations into account while designing your new veneers, especially if you’ll be getting them for some but not for all your teeth. In that case, it’s important for the veneer color to blend seamlessly with the color of your natural teeth without veneers.
Your new smile expectations and desires are also important and should be considered when designing veneer coloring. For instance, do you want a more natural look—or would you prefer a smile with more “dazzle”? This could have an impact on color.
Your dentist takes all of this information (including your input) and communicates it clearly to the dental lab technician creating the veneers. That process is a combination of both science and artistry, using a variety of techniques to achieve an accurate, life-like texture and color result. For example, a technician may paint the edges of the veneers with a ceramic paste that when cured produces a life-like translucency.
This meticulous attention to color detail is necessary to create beautiful veneers that look natural. If the color is right, you’re sure to enjoy the change your veneers bring to your smile for many years to come.
