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.

A root canal treatment is a highly effective way to save a deeply decayed tooth. Sometimes, though, complications make it difficult or even impossible to perform the traditional procedure. In those cases, we may need to use a different option.
Tooth decay becomes an imminent threat to a tooth's survival if it works its way into the pulp, the innermost layer of a tooth. It's only a short advancement from there into the roots by way of the root canals.
In a typical root canal treatment, we access the pulp by drilling a small hole in the biting surface of a back tooth or the back side of a front tooth. We remove all the tissue within the pulp and fill it and the root canals with a special filling to prevent re-infection. After sealing the access hole, we cap the tooth with a crown to further protect it.
Although root canal treatments have a high success rate, re-infection can still occur. Often, a second root canal will save the tooth from the new infection.
In some cases, though, using the traditional procedure might do more harm than good. It's possible we may find extra canals previously undetected branching out from the primary canal at the root end. Canals can calcify and narrow, making them extremely difficult to fill. Subsequent dental work may also prove troublesome: we would have to take the restoration apart, which could further weaken the tooth.
The alternative is a procedure known as an apicoectomy. Instead of accessing the pulp through the crown, we access the root end through the gum tissue. We then focus on removing infected tissue at the tooth's root end, along with a tiny amount of the root tip. We then place a small filling at the end of the root canal (essentially plugging it up) to prevent further infection. We may also perform grafting to encourage bone growth in any voids left by the procedure.
Endodontists, specialists in root canals, have the advanced training and specialized equipment to perform an apicoectomy. With their expertise, they may be able to save your tooth with this specialized procedure when a root canal treatment won't work.
