Root canal treatments have suffered a bad rap over the years—and undeservedly. While we applaud root canal therapy for the millions of decayed teeth the procedure has saved, the worn-out cliché that it's painful still lingers on.
So, let's set the record straight: a root canal treatment doesn't cause pain, it most often relieves it. Let's look a little closer at what actually happens before, during and after this tooth-saving treatment.
Before: a tooth in crisis. Tooth decay can damage more than a tooth's outer enamel. This aggressive bacterial infection can work its way into a tooth's interior, destroying the nerves and blood vessels in the pulp, before moving on to the roots and supporting bone through the root canals. Untreated, this devastating process can lead to tooth loss. A root canal treatment, however, can stop the invading decay and save the tooth.
During: stopping the disease. The dentist first numbs the tooth and surrounding gum tissues with local anesthetic—the only thing you might normally feel during treatment is a slight pressure. They then drill into the tooth to access the inner pulp and root canals and remove all diseased tissue. Once the interior spaces of the tooth have been disinfected, the dentist then fills the empty pulp chamber and root canals with a pliable filling called gutta percha to prevent future infection.
After: preventing re-infection. With the filling complete, the dentist then seals the access hole. There may be some minor soreness for a few days, similar to the aftermath of a routine filling, which can usually be managed with over-the-counter pain relievers like ibuprofen. Sometime later, the dentist will normally finish the treatment with a new crown on the tooth. This accomplishes two things: It helps strengthen the tooth against stress fracturing and it provides another layer of protection against future decay.
Root canal treatments have an exceptional track record for giving diseased teeth a second chance. There's nothing to fear—and everything to gain for your troubled tooth.

Children have a lot of energy that's often channeled through physical activities and sports. Unfortunately, this also increases their risk of injuries, particularly to their teeth.
Injuries to the mouth can endanger permanent teeth's survival. For an older tooth, a root canal treatment might be in order. Not so, though, for a pre-adolescent tooth, even if it is permanent.
A young permanent tooth is still developing dentin, the large layer just below the enamel. This growth depends on the connective tissue, blood vessels and nerves within the pulp in the center of the tooth. Because a root canal treatment removes all of this tissue, it could stunt dentin and root growth and endanger the tooth's future.
Instead, we may need to treat it with one of a number of modified versions of a root canal, depending on what we find. If the tooth's pulp is unexposed, for example, we may need only to remove the damaged dentin, while still leaving a barrier of dentin to protect the pulp. We then apply an antibacterial agent to minimize infection and fill in the area where we've removed tooth structure.
If some of the pulp is exposed, we may perform a pulpotomy to remove just the affected pulp and any overgrown tissue. We then place a substance that encourages dentin growth and seal it in with a filling. If we go deeper toward the root end, we might also perform procedures that encourage the remaining pulp to form into a root end to stabilize the tooth.
If the entire pulp has been damaged beyond salvage, we may then turn to a procedure called an apexification. In this case we clean out the pulp chamber; at the root end we place mineral trioxide aggregate (MTA), a growth stimulator that encourages surrounding bone to heal and grow. We then fill in the root canals and chamber with a special filling called gutta percha to seal the tooth.
The deeper we must penetrate into the pulp, the higher the chances the young tooth's dentin and roots won't form properly, leading to later problems and possible loss. But by employing the appropriate one of these methods, we can minimize the risk and give your child's damaged tooth a fighting chance.
