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!
