TheresStillHopeforaRe-InfectedToothAfterRootCanalTreatment

Most first-time root canal treatments achieve their purpose in saving an internally decayed tooth and extending its life to match those of the patient’s non-decayed teeth. Occasionally, though, a root canal-treated tooth may become re-infected by decay.

There are a number of reasons for this: the permanent crown meant to add further protection against decay may have been delayed, giving bacteria an opening to re-infect the tooth; it’s also possible the original seal for the pulp chamber and root canals after filling wasn’t sufficient to prevent bacterial contamination.

There‘s also another reason that’s very difficult to foresee — the presence of narrow, curved root canals in the tooth that can pose complications during the procedure. Some of these known as accessory or lateral canals branch off the main canals to create a complex network that’s difficult to detect during the initial procedure. If they’re not cleaned out and filled during the procedure any tissue trapped in them can remain infected and ultimately die. If these canals also open into the periodontal membrane at the attachment between the teeth and bone, the infection can spread there and become a periodontal (gum) infection that can trigger future tooth loss.

Fortunately, a reoccurrence of infection isn’t necessarily a death sentence for a tooth. A second root canal treatment can correct any problems encountered after the first treatment, especially complications from accessory canals. It may, though, require the advanced skills of an endodontist, a dental specialist in root canal problems. Endodontists use microscopic equipment to detect these smaller accessory canals, and then employ specialized techniques to fill and seal them.

If you encounter pain or other signs of re-infection for a tooth previously treated with a root canal procedure, contact us as soon as possible. The sooner we can examine and diagnose the problem, the better your tooth’s chances of survival by undergoing a second root canal treatment.

WhatHappensinaRootCanalTreatmentandHowitCanSaveYourTooth

Along with periodontal (gum) disease, tooth decay poses one of the two greatest threats to your teeth. Cavities are just the start: if decay invades the pulp, the tooth’s innermost layer, the infection created can continue to advance through the root canals to the supporting bone. This worst case scenario could cost you your tooth.

But we can stop this advanced decay in its tracks with a procedure called a root canal treatment. A root canal essentially removes all the infected tissue within the tooth and then seals it from further infection. And contrary to its undeserved reputation for being painful, a root canal can actually stop the severe tooth pain that decay can cause.

At the beginning of the procedure, we deaden the affected tooth and surrounding tissues with local anesthesia—you’ll be awake and alert, but without pain. We then isolate the tooth with a dental dam of thin rubber or vinyl to create a sterile environment around it to minimize contamination from bacteria found in saliva and the rest of the mouth.

We then drill a small hole through the enamel and dentin to access the interior of the tooth. With special instruments, we remove and clean out all the diseased or dead tissue in the pulp chamber and root canals. After disinfecting the empty spaces with an antibacterial solution, we’ll shape the root canals to make it easier to perform the next step of placing the filling.

To fill all the root canals and pulp chamber, we typically use a rubber-like material called gutta-percha. Because it’s thermoplastic (“thermo”—heat; “plastic”—to shape), we can compress it into and against the walls of the root canals in a heated state to fully seal them. This is crucial for preventing the empty tooth interior from becoming re-infected. Afterward, we’ll seal the access hole with its own filling; later, we’ll bond a permanent crown to the tooth for additional protection and cosmetic enhancement.

After the procedure you may have some temporary minor discomfort usually manageable with aspirin or ibuprofen, but your nagging toothache will be gone. More importantly, your tooth will have a second chance—and your dental health and smile will be the better for it.

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.

NeedaRootCanalHeresaStep-by-StepGuideonWhattoExpect

You’ve recently learned one of your teeth needs a root canal treatment. It’s absolutely necessary: for example, if you have decay present, it will continue to go deeper within the tooth and it will spread to the roots and bone and could ultimately cause you to lose your tooth. Although you’re a little nervous, we can assure you that if we’ve recommended a root canal treatment, it’s the right step to take for your dental health.

There’s nothing mysterious — or ominous — about a root canal. To help ease any fears you may have, here’s a step-by-step description of the procedure.

Step 1: Preparing your mouth and tooth. We first take care of one of the biggest misconceptions about root canals: that they’re painful. We completely numb the tooth and surrounding tissues with local anesthesia to ensure you will be comfortable during the procedure. We isolate the affected tooth with a thin sheet of rubber or vinyl called a rubber dam to create a sterile environment while we work on the tooth. We then access the inside of the tooth — the pulp and root canals — by drilling a small hole through the biting surface if it’s a back tooth or through the rear surface if it’s in the front.

Step 2: Cleaning, shaping and filling the tooth. Once we’ve gained access we’ll clear out all of the dead or dying tissue from the pulp and root canals, and then cleanse the empty chamber and canals thoroughly with antiseptic and antibacterial solutions. Once we’ve cleaned everything out, we’ll shape the walls of the tiny root canals to better accommodate a filling material called gutta-percha, which we then use to fill the canals and pulp chamber.

Step 3: Sealing the tooth from re-infection. Once we complete the filling, we’ll seal the access hole and temporarily close the tooth with another filling. Later, we’ll install a permanent crown that will give the tooth extra protection against another infection, as well as restore the tooth’s appearance.

You may experience some mild discomfort for a few days after a root canal, which is usually manageable with aspirin or ibuprofen. In a week or so, you’ll hardly notice anything — and the tooth-threatening decay and any toothache it may have caused will be a distant memory.
