Bad news at your last dental visit: You have a decayed tooth. And not just in the enamel—the decay has invaded the tooth's inner pulp and the resulting infection is threatening the supporting bone structure.
You're thinking that tooth is toast. Then comes the good news: your dentist believes the tooth can be rescued with a root canal treatment.
But then you begin thinking about how often Uncle Sid says he'd rather undergo a colonoscopy than have a root canal. Is the procedure really as painful and uncomfortable as popular culture says it is? What is a root canal really like?
First step: Things go numb. Uncle Sid is wrong: A root canal treatment is painless because your dentist will first make sure the entire area involving the tooth is anesthetized. This does involve injecting the local anesthetic deep within the tissues, but you won't even feel the needle prick thanks to topical anesthesia applied to the surface gums.
Second step: Drilling deep. After applying a protective dam to isolate the infected tooth from its neighbors, your dentist will drill a small access hole through the enamel and dentin to reach the pulp and root canals. If it's one of the larger back teeth, the access hole is usually drilled in the tooth's biting surface; in a front tooth, the hole is usually located on the tongue side.
Third Step: Removing diseased tissue. Using special instruments, your dentist will remove the diseased tissue in the pulp and root canals, essentially stopping the infection and any tooth pain you've been experiencing. The empty pulp chamber and canals are often then disinfected with a special antibacterial solution.
Fourth Step: Protecting the tooth. After some shaping, the pulp chamber and root canals are filled with a special filling to prevent further infection. The access hole is then filled and sealed to complete the procedure. At some point in the future, the tooth typically will need a crown to add support and further protection.
You may have some minor discomfort afterward, but this can usually be managed with a mild pain reliever like ibuprofen or acetaminophen. After a week or so, you'll be good as new—and so will your tooth.

With smart phone in hand, you can instantaneously find out just about anything. Unfortunately, online search results aren’t always accurate. Case in point: there’s an idea floating on the World Wide Web that root canal treatments cause cancer.
Sounds ludicrous? Yes, but like other strange ideas this one has historical roots (pardon the pun). In the early 20th Century, a dentist named Weston Price propagated the idea that leaving a “dead” organ in the body caused health problems. By his view, a root canal-treated tooth fell into this category and could potentially cause, among other things, cancer.
But concern over root canal treatment safety is on shaky ground: dentistry examined Dr. Price’s ideas over sixty years ago and found them wanting. But first, let’s look at what a root canal treatment can actually do for your health.
Tooth decay is an infection that first attacks the outer tooth enamel and then continues to advance until it infects the inner pulp. It can then travel through the root canals to the roots and bone. Without intervention, the infection will result in tooth loss.
We use a root canal treatment to save the tooth from this fate. During the procedure we remove and disinfect all of the diseased or dead tissue within the pulp and root canals. We then fill the empty chamber and canals with a special filling and seal the tooth to prevent any further infection. And while technically the procedure renders a tooth unable to respond to thermal sensitivity or tooth decay, the tooth is still alive as it is attached to the periodontal ligament and its blood supply and nerve tissue. The tooth can still “feel” if you bite on something too hard and it doesn’t affect the tooth’s function or health, or a patient’s overall health for that matter.
As to Dr. Price’s theory, extensive studies beginning in the 1950s have examined the potential health risk of root canal treatments. The latest, a 2013 patient survey study published in a journal of the American Medical Association, not only found no evidence linking root canal treatment to cancer, but a lower risk of oral cancer in 45% of patients who had undergone multiple root canal treatments.
While root canal treatments do have potential side effects, none are remotely as serious as this online “factoid” about cancer. It’s far more likely to benefit your health by saving your tooth.

It’s absolutely critical to stop tooth decay and repair any damage to tooth structure. Hopefully, we’ve caught it early in the enamel and dentin where we’re able to repair any holes or “cavities” that might have developed by filling them.
But what if the decay has crept deeper into the interior of the tooth? In this case, you’re at a much higher risk of eventually losing the tooth. If the decay has spread into the bone, a root canal treatment is usually your best option.
The first sign that decay has invaded the pulp, the innermost layer of the tooth, and the root canals may be a severe toothache. It’s different from the wince of pain or discomfort caused by sensitivity to temperature or pressure. Inner decay pain is constant and often excruciating. This is because the infection is attacking the nerves bundled within the pulp chamber.
The pain can last for several days, and then suddenly stop altogether. No pain is good news, right? Wrong — the pain has stopped because the infected nerves have finally died and can no longer signal the brain. The infection, though, is very much alive and will continue to advance toward the root where the damage may eventually cause you to lose the tooth.
A root canal treatment removes decay in the pulp chamber and canals. We first drill an access hole to enter the pulp chamber. Once inside, we use special instruments to completely remove all tissue and disinfect the empty chamber. We then fill the chamber and root canals with a special filling and seal the access hole to prevent further decay. A few weeks later we install a custom crown to protect the tooth further.
If you have a toothache, or you’ve had one that suddenly went away, you should schedule an appointment for a dental examination as soon as possible: this is the only way to accurately determine the cause of the pain. If a root canal is deemed necessary, the sooner we perform it, the less chance the infection will cause you to lose your tooth.

Primary (baby) teeth might not last long, but their impact can last a lifetime. Their first set of teeth not only allows young children to eat solid foods, but also guide permanent teeth to form and erupt in the proper position.
Unfortunately, primary teeth aren't immune to tooth decay. If the decay is extensive, the tooth may not last as long as it should. Its absence will increase the chances the permanent teeth won't come in correctly, which could create a poor bite (malocclusion) that's costly to correct.
If a primary tooth is already missing, we can try to prevent a malocclusion by installing a “space appliance.” This keeps nearby teeth from drifting into the empty space intended for the permanent tooth. The best approach, though, is to try to save a primary tooth from premature loss.
We can often do this in much the same way as we would with a permanent tooth — by removing decayed material and filling the prepared space. We can also perform preventive applications like topical fluoride or sealants that strengthen or protect the tooth.
It becomes more complicated, though, if the pulp, the interior of the tooth, becomes decayed. The preferred treatment for this in a permanent adult tooth is a root canal treatment. But with a primary tooth we must also consider the permanent tooth forming below it in the jaw and its proximity to the primary tooth. We need to adapt our treatment for the least likely damage to the permanent tooth.
For example, it may be best to remove as much decayed structure as possible without entering the pulp and then apply an antibacterial agent to the area, a procedure known as an indirect pulp treatment. We might also remove only parts of the pulp, if we determine the rest of the pulp tissue appears healthy. We would then dress the wound and seal the tooth from further infection.
Whatever procedure we use will depend on the extent of decay. As we said before, our number one concern is the permanent tooth beneath the primary. By focusing on the health of both we can help make sure the permanent one comes in the right way.

Your tooth is in peril if its innermost layer, the pulp, becomes infected and inflamed. Deep tooth decay, repeated dental procedures or fractures can all expose the pulp and ultimately the roots to infection and lead to tooth loss.
But that scenario isn't inevitable — we can often save the tooth with a root canal treatment. By accessing the tooth's interior through a prepared hole, we're able to clean out the infected tissue in the pulp chamber and root canals, and fill the empty space with a special filling. We then cap the tooth with a custom crown to protect it from a re-infection.
Root canal treatments have a very high success rate — chances are good your tooth will survive for many years afterward. But there's a slight chance the tooth may become re-infected; in that case, a second root canal treatment may be in order.
In a few cases, though, a second root canal may not be advisable, and could even accelerate damage to the tooth. For example, if past dental work resulted in an extensive crown restoration, accessing the root canals the conventional way will require disassembling that restoration. This could weaken the tooth significantly.
We can approach the problem from a different route: instead of accessing the tooth's interior through the crown (the visible part of the tooth), we instead perform a surgical procedure called an apicoectomy, which accesses the tooth at the root end through the gums.
In this procedure we numb the area with local anesthesia and then make a small incision through the gums at the level of the affected root. After access, we remove any diseased tissue around the root and a few millimeters of the root tip itself. We then insert a small filling in its place to seal the canal and prevent further infection. In some cases we may also insert a graft to encourage bone growth and aid in healing.
Over time, the affected area will heal and return to normal function. Even if a traditional root canal treatment can't be used, an apicoectomy could be another option for saving your tooth.
