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.

For most people, going to the dentist is as routine as getting their oil changed. But if you're like the one in ten people with severe anxiety, dental visits are anything but routine.
What may have begun as a childhood fear has turned for many people into a lifetime avoidance of dental care. Â This absence of dental cleanings, checkups and treatments can have an adverse effect on not only their oral health but their general health too.
But there are ways you can reduce dental visit anxiety, beginning first with finding a compassionate dental provider. A good dentist-patient relationship is important for everyone, but more so for people with anxiety. Building a trust relationship with a dentist who listens and accepts your fears without judging is your first step to overcoming them.
Though finding an understanding provider is important, it may not be enough in the beginning of your return to regular dental care. To help you further relax during visits, we can also provide medicinal therapies known collectively as sedation.
Although it has some similarities, sedation is different from anesthesia. The latter deadens pain sensation; sedation aims to calm your emotions. The most common sedation is taken in oral form, usually a pill (or syrup for children) taken an hour or so before the appointment. Oral sedation is often used in conjunction with gases like nitrous oxide and local anesthesia.
For a more relaxed state (especially during an involved procedure) we may use intravenous (IV) sedation. With this method we deliver the medication through a small needle or catheter inserted into a vein.
IV sedation places you in a reduced state of consciousness. But it isn't a “sleep” state as what's achieved during general anesthesia, but more of a “semi-awake” state. You won't need assistance with breathing or heart function and you can respond to verbal or touch commands. Many drugs used for IV sedation also have an amnesiac affect, so you won't remember many details about the procedure.
Depending on your level of anxiety, we can match the right therapy to induce calm and relaxation. Sedation can help you see dental visits in a more positive light so that it truly does become a life routine.

When die-hard music fans hear that their favorite performer is canceling a gig, it’s a big disappointment—especially if the excuse seems less than earth-shaking. Recently, British pop sensation Dua Lipa needed to drop two dates from her world tour with Bruno Mars. However, she had a very good reason.
“I’ve been performing with an awful pain due to my wisdom teeth,” the singer tweeted, “and as advised by my dentist and oral surgeon I have had to have them imminently removed.”
The dental problem Lipa had to deal with, impacted wisdom teeth, is not uncommon in young adults. Also called third molars, wisdom teeth are the last teeth to erupt (emerge from beneath the gums), generally making their appearance between the ages of 18-24. But their debut can cause trouble: Many times, these teeth develop in a way that makes it impossible for them to erupt without negatively affecting the healthy teeth nearby. In this situation, the teeth are called “impacted.”
A number of issues can cause impacted wisdom teeth, including a tooth in an abnormal position, a lack of sufficient space in the jaw, or an obstruction that prevents proper emergence. The most common treatment for impaction is to extract (remove) one or more of the wisdom teeth. This is a routine in-office procedure that may be performed by general dentists or dental specialists.
It’s thought that perhaps 7 out of 10 people ages 20-30 have at least one impacted wisdom tooth. Some cause pain and need to be removed right away; however, this is not always the case. If a wisdom tooth is found to be impacted and is likely to result in future problems, it may be best to have it extracted before symptoms appear. Unfortunately, even with x-rays and other diagnostic tests, it isn’t always possible to predict exactly when—or if—the tooth will actually begin causing trouble. In some situations, the best option may be to carefully monitor the tooth at regular intervals and wait for a clearer sign of whether extraction is necessary.
So if you’re around the age when wisdom teeth are beginning to appear, make sure not to skip your routine dental appointments. That way, you might avoid emergency surgery when you’ve got other plans—like maybe your own world tour!

As a saying, “Necessity is the mother of invention” is no more appropriate than when you have something caught between your teeth. And humans, as inventive and creative as we are, have used a weird assortment of items—usually within arms' reach—to dislodge a pesky bit of food.
According to a recent survey, more than three-fourths of Americans admit to using a number of “tools” to clean between teeth including twigs, nails (the finger and toe variety), business cards or (shudder!) screwdrivers. And it's one thing to do this alone, but among dinner companions and other folk it's a definite faux pas.
Usually, it's smarter and more economical if you can use a particular tool for many different applications. But when it comes to your teeth, you should definitely go with a “unitasker” designed specifically for the job: dental floss. It's not only the safest item you can use to clean your teeth, it's specifically designed for that purpose, especially to remove disease-causing plaque from between teeth.
Of course, the reason many of us use alternate items for cleaning between teeth is that they're the closest ones at hand. You can remedy this by keeping a small spool (or a short length) of dental floss or floss picks handy for those moments you encounter a wedged piece of food. In a pinch, you can use a rounded toothpick (better for your gums than the flat variety).
At home if you find flossing difficult, consider using a water flosser. This handheld device emits a pulsating stream of pressurized water that loosens and flushes away plaque and bits of food remnant. It's ideal for people who have a hard time maneuvering floss or who wear braces, which can block regular floss thread from accessing between teeth as fully as possible.
In any case, use the other “tools” at hand for whatever they're intended. When it comes to what's best for your teeth, use floss to keep the in-between clear and clean.
The Internet is truly amazing: It takes only a few seconds to tap into a vast store of knowledge to find information that once took people hours or days. But amidst all that helpful data, there's also some not so helpful information—in fact, some can be downright harmful, including to your dental health.
One particular Internet trend is brushing teeth with black, gooey substances containing activated charcoal. Scores of online videos featuring people doing this are getting viral views, perhaps more for the “gross” factor than the claimed health benefits.
So, why do it? Advocates of using activated charcoal for oral hygiene claim the ingredient kills harmful microorganisms in your mouth. The charcoal is also supposed to whiten your teeth.
But clinical studies of the practice, including one recently published in the Journal of the American Dental Association have been unable to substantiate these claims. There's simply no evidence that activated charcoal does what its advocates say it can do.
Unfortunately, there is evidence the practice can actually harm your teeth. This is because activated charcoal is an abrasive substance that over time could damage your teeth's enamel. Eroded enamel doesn't regrow, so eventually the more vulnerable dentin, the tooth layer just beneath the protective enamel, becomes exposed. It's not only darker and less attractive than enamel, its more susceptible to tooth decay and cavities.
The best way to care for your teeth, brushing and flossing daily, may seem boring compared to videos of brushing with charcoal, but it is effective—and safe. You should also see your dentist for more thorough cleanings at least every six months to round out your dental care.
And if you want a brighter smile, your dentist can perform a tooth whitening procedure that can give you months or even years of satisfaction. Professional tooth whitening (or even home whitening kits applied properly) also won't harm your enamel.
