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.

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.

As in other parts of medicine, lasers are beginning to change the way we provide dental care. More and more dentists are using lasers to make earlier diagnoses of dental disease or provide surgical treatment. One area prime for change is the treatment of teeth with deep decay and in danger of being lost.
For decades now, the best way to save teeth in this condition is with root canal treatment. In this common procedure we access the pulp, remove the infected tissue with specialized hand instruments, and then fill and seal the pulp chamber and root canals with a special filling.
We can now potentially improve the efficiency and increase the success rate of this treatment with laser technology. With their focused light, lasers emit a concentrated burst of energy that's extremely precise. In many instances laser energy can remove the target diseased tissue without damaging nearby healthy tissue.
In this form of root canal treatment, we use lasers to remove tissue and organic debris within the pulp and then shape the root canal walls to better receive the filling. We can also utilize the heat from laser energy to soften and mold the filling, so that it better conforms within the walls of the root canals.
Using lasers in root canal treatments may require less local anesthesia than the traditional approach and also eliminates disturbing or discomforting sounds and vibrations. Dentists who've used the new technology also report less bleeding during the procedure and less pain and occurrences of infection afterwards.
But there are a couple of disadvantages for using lasers in root canal treatment. For one, light travels in a straight line — and many root canal networks are anything but straight. More complex root canal networks may still require the traditional approach. Laser energy could also increase the tooth's inner temperature, which could potentially damage tissues even on the tooth's outer surfaces.
Used in the right circumstances, though, lasers can be an effective means to treat diseased teeth. Â As laser technology continues to advance and becomes a mainstay in dental care, you may soon find it part of your next dental procedure.
