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.

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.

Primary (baby) teeth don't last long. But despite their short life span, they do a number of important things, like enabling a child to eat solid food. But perhaps their most important long-term function is “paving” the way for their permanent replacements.
If one is lost prematurely, though, the permanent tooth might not come in properly aligned. That's why if a primary tooth is in danger of loss due to decay or injury, we'll do our best to save it.
But that could get a little tricky if the infected or damaged part of the tooth is the innermost pulp. If it were an adult tooth, the best course might be a root canal treatment: access the pulp, clear out the diseased tissue, and then fill the space with a special filling. But with a primary tooth (or a young permanent tooth for that matter) that may not be advisable.
That's because the pulp plays a more important role in a child's tooth than an adult's. Its nerves and other tissues stimulate dentin growth; a full root canal could disrupt that growth and weaken the tooth in the long run.
With a child's tooth, we proceed carefully depending on how infected or damaged the pulp might be. If it's only slightly exposed or not at all, we try then to remove as much decayed tooth material outside the pulp as necessary, then apply antibacterial agents or dentin growth stimulators.
If we do have pulp exposure, we'll try to remove only as much of the affected pulp as necessary through a procedure called a pulpotomy. This technique will only be used if the remaining pulp looks healthy or restorable to health.
If not, we may need to perform a pulpectomy to remove the entire pulp. Most like a typical root canal, it's a last resort: without the pulp, dentin growth could be stunted and the tooth won't develop as healthy as it should.
Of course, the best approach is to prevent teeth from developing such problems in the first place. So, be sure to practice effective daily hygiene with your child and keep up regular dental visits beginning at age one.
