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.

3FactorsThatCouldAffecttheSuccessofaRootCanalTreatment

A tooth with deep decay is in real peril. If the disease isn’t stopped, it can eventually infect the bone and greatly increase the risk of losing the tooth. But tooth decay removal and a root canal treatment can stop advancing decay and resulting infection in its tracks.

During this common procedure we first drill into the tooth to access the inner pulp. After removing the infected pulp tissue, we disinfect and fill the empty chamber and root canals with gutta percha. We then seal the tooth and crown it to protect against re-infection.

But while most root canals are successful and long-lasting, sometimes the tooth becomes re-infected. Here are 3 factors that could affect the long-term success of a root canal treatment.

Early treatment. Like many health problems, the sooner we detect decay and treat it, the better the outcome. A tooth in which the infection has already advanced beyond the pulp is at greater risk for re-infection than one in which the infection is localized in the pulp. Keeping up your regular dental visits as well as seeing the dentist at the first sign of abnormality—spots on the teeth or pain—can increase your chances of early diagnosis.

Tooth complications. Front teeth with their single roots and canals are much easier to access and treat than a back molar with an intricate root canal network. Root canals can also be extremely narrow making them easy to miss during treatment. In cases like this the expertise and advanced equipment of an endodontist (a specialist in root canal treatment) could help increase the odds of success in complex situations.

The aging process. Teeth do wear over time and become more brittle, making them increasingly susceptible to fracture. A previous root canal treatment on an aging tooth might also increase the fracture risk. To avoid this, it’s important for the tooth to receive a crown after the procedure to protect the tooth not only from re-infection but undue stress during chewing. In some situations, we may also need to place a post with a bonded composite buildup within the tooth to give it extra support.

Even if a tooth has these or similar complications, a root canal treatment may still be advisable. The benefits for preserving a decayed tooth often far outweigh the risks of re-infection.

EarlyActionNeededtoSaveYourToothfromRootResorption

Along with the gums, your teeth’s roots help stabilize them. Without them your teeth couldn’t handle the normal biting forces you encounter every day. That’s why a rare condition called root resorption must be treated promptly: this gradual breakdown and dissolving of root structure could eventually cause you to lose your tooth.

Resorption is normal in primary (“baby”) teeth giving way for permanent teeth or sometimes during orthodontic treatment. But the form of resorption we’re referring to in permanent teeth isn’t normal, and is highly destructive.

The condition begins in most cases outside the tooth and works its way in, usually at the gum line around the cervical or “neck-like” region of the tooth (hence the term external cervical resorption or ECR). ECR produces pink spots on the teeth in its early stages: these are spots of weakened enamel filled with pink-colored cells that cause the actual damage. The cells create cavity-like areas that can continue to enlarge.

We don’t fully understand what causes ECR, but there seems to be links with excessive force during orthodontics, tooth trauma (especially to the gum ligaments), tooth grinding habits or internal bleaching procedures. However, most people with these problems don’t develop ECR, so the exact mechanism remains a bit of a mystery.

The good news, though, is that we can treat ECR effectively, provided we discover it before it inflicts too much damage. That’s why regular dental visits are important, coupled with your own observation of anything out of the ordinary and immediate dental follow-up.

If the affected area is relatively small, we may be able to remove the cells causing the damage and repair the area with a tooth-colored filling. If it appears the pulp (the tooth’s innermost layer) is involved, we may need to perform a root canal treatment to remove infected tissue and fill the empty space with a special filling. You may also need other procedures to reduce the chances of gum recession around the affected tooth.

Proactive dental care is your best insurance against losing a tooth to root resorption. So keep an eye on your teeth and see your dentist regularly to keep your teeth and gums healthy.

ToothTypeandConditioncanAffectRootCanalTherapyEffectiveness

Root canal therapy is the unsung "hero" of dentistry. Although often falsely maligned as an unpleasant experience, millions of decayed teeth have been saved thanks to this routine treatment.

But although root canal therapy can save your tooth, we can't guarantee it won't be affected by another infection. There are other factors to consider how long a treated tooth will remain healthy.

Root canal therapy stops and limits the damage from tooth decay that has infected the inner pulp and root canals. A dentist or endodontist (a root canal specialist) drills into the tooth to gain access to the pulp. They remove the diseased pulp tissue and then fill the empty pulp chamber and root canals with a specialized filling called gutta percha. The tooth is then sealed and later crowned to protect it against future fracture or infection.

The probability of that occurring may depend on when a dentist performs the root canal in the disease progression—and the earlier the better. If decay has already infected the underlying bone, the tooth's long-term prognosis even with root canal therapy could be dim. That's why you should see a dentist as soon as possible for any tooth pain, even if it goes away.

The type of tooth could impact long-term health. Teeth with single roots are usually easier to treat. But those with multiple roots and an intricate root canal network can be more difficult to treat, and require specialized equipment and techniques.

Age can also impact root canal therapy longevity. The older a root canal-treated tooth is, the more brittle and susceptible to fracture it can become, which can pose complications. That's why we typically place crowns on treated teeth to protect them from both future infection and undue stress created while biting and chewing.

To help mitigate these possible factors, you should see your dentist regularly for checkups and at the first sign of pain or other abnormalities for the earliest treatment possible. And for more complex tooth issues, your dentist may refer you to an endodontist to perform your root canal. With early intervention and attentive care, your root canaled tooth could enjoy many years of life.

RootCanalTreatmentAlleviatesPainandSavesYourTooth

If you’re undergoing your first root canal treatment, it’s understandable if you’re apprehensive. So, let’s cut to the chase about your biggest fear: a root canal treatment doesn’t cause pain, it relieves it — and saves your tooth too.

You need this procedure because decay has spread deep into your tooth’s inner pulp. The infection has already attacked the nerves bundled within the pulp chamber, the source of the pain that led you to us in the first place.

The real concern, though, is the infection continuing to travel through the canals of the tooth root. If that happens, you’re in danger of not only losing the tooth, but also losing surrounding bone, adjacent teeth or damaging other important structures close by. Our goal is simple: remove the infected pulp tissue and seal the empty chamber and root canals from further infection with a special filling.

We begin by numbing the tooth with local anesthesia — you won’t feel anything but slight pressure as we work. After placing a dental dam — a thin sheet of rubber or vinyl — around the affected tooth to maintain a clean work area, we drill a small hole through the biting surface of a back tooth or in the rear surface of a front tooth. We’ll use this hole to access the pulp, where we’ll first remove all the dead and diseased tissue from the chamber. We’ll then disinfect the chamber and root canals with antiseptic and antibacterial solutions.

After some shaping, we’ll fill the chamber and canals, usually with gutta-percha that’s malleable when heated and can be compressed into and against the walls of the root canals to completely seal them. We’ll then seal the access hole.

You may have a few days of mild discomfort afterward, which can be managed generally with pain relievers like aspirin or ibuprofen. Later, we’ll permanently restore the tooth using filling to seal the root canal inside the tooth followed by a custom crown that’s fit over and bonded to the tooth. This will further minimize chances of a re-infection.

If we’ve recommended a root canal, then we think your tooth should be saved instead of extracted. The procedure will end the pain you’ve been suffering and give your tooth a new lease on life.
