RootCanalsareaSafeWaytoSaveTeeth

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.

HughJackmanIsAllSmilesforHisNewBroadway-InspiredShow

To anyone immersed in the “X-Men Universe” Hugh Jackman will always be Wolverine, a role he played in seven movies. But there’s more to this Australian actor than mutant bone claws and mutton chops that would make Elvis envious. Jackman has also starred in over 20 non-superhero films, including Les Misérables, for which he won a Golden Globe. He is also a Tony award-winning Broadway performer—with a winning smile.

With his famed character Logan/Wolverine fading in the rearview mirror, Jackman has returned to his musical roots. He will play Harold Hill in the Broadway revival of The Music Man, set to open in Fall 2020. And since May 2019 he’s been on world tour with Hugh Jackman: The Man. The Music. The Show., featuring Jackman and a supporting cast performing songs from favorite shows and films, including Les Misérables and the 2017 hit The Greatest Showman.

The Show, with 90 planned stops throughout Europe, North America and Oceania, is a decidedly different “universe” from the X-Men. As Wolverine, Jackman could get away with a scruffier look. But performing as Jean Valjean or the bigger-than-life P.T. Barnum, he has to bring a vastly different look to the role, which brings us to Jackman’s teeth…

Once upon a time, Jackman’s teeth were an unflattering gray—definitely not a good look for stage or film. So with the help of his dentist, Jackman set about upgrading his smile with teeth whitening. Teeth whitening is a great way to take a dull, stained smile and turn up the volume on its brightness—and attractiveness—a notch or two. A dentist applies a bleaching solution that stays in contact with the teeth for a few minutes. The process is often aided by special lighting.

A professional application is especially desirable if, like Jackman, you want “Goldilocks” brightness: not too little, not too much, but just right for you. Dentists can precisely control the tint level to get a brighter but more naturally looking white. Of course, you can also get a dazzling “Hollywood” smile if you so desire.

And although the effect of teeth whitening isn’t permanent, a dental application can last a while, depending on how well you manage foods and beverages that stain teeth. With a touchup now and then, you may be able to keep your brighter smile for years before undergoing the full procedure again.

One important note, though: This technique only works with outer enamel staining. If the discoloration originates from within the tooth, the bleaching agent will have to be placed internally, requiring access to the inside of the tooth. An alternative would be porcelain veneers to mask the discoloration, an option that also works when there is ultra-heavy enamel staining.

If you’re tired of your dull smile, talk with us about putting some pizzazz back into it. Teeth whitening could be your way to get a smile worthy of Broadway.

SeeYourDentisttoFindouttheRealCauseforYourToothPain

If you have tooth pain, we want to know about it. No, really—we want to know all about it. Is the pain sharp or dull? Is it emanating from one tooth or more generally? Is it constant, intermittent or only when you bite down?

Dentists ask questions like these because there are multiple causes for tooth pain with different treatment requirements. The more accurate the diagnosis, the quicker and more successful your treatment will be.

Here are 3 different examples of tooth pain, along with their possible causes and treatments.

Tooth sensitivity. If you feel a quick jolt of pain when you eat or drink something hot or cold, it may mean your gums have drawn back (receded) from your teeth to leave more sensitive areas exposed. Gum recession is most often caused by gum disease, which we can treat by removing dental plaque, the main cause for the infection. In mild cases the gums may recover after treatment, but more advanced recession may require grafting surgery.

Dull ache around upper teeth. This type of pain might actually be a sinus problem, not a dental one. The upper back teeth share some of the same nerves as the sinus cavity just above them. See your dentist first to rule out deep decay or a tooth grinding habit putting too much pressure on the teeth. If your dentist rules out an oral cause, you may need to see your family physician to check for a sinus infection.

Constant sharp pain. A throbbing pain seeming to come from one tooth may be a sign the tooth's central pulp layer has become decayed. The resulting infection is attacking the pulp's nerves, which is causing the excruciating pain. Advanced decay of this sort requires a root canal treatment to remove the diseased tissue and fill the empty pulp chamber and root canals to prevent further infection. See your dentist even if the pain stops—the infection may have only killed the nerves, but is still present and advancing.

Pain is the body's warning system—so heed the tooth pain alert and see your dentist as soon as possible. The sooner the problem is identified and treated, the better your chances of returning to full dental health.
