A traditional root canal procedure can be a “life-saver” for a decayed or injured tooth. But while it’s usually the best course for a damaged adult tooth, variations of the procedure are advisable for a new permanent tooth in a child or young adolescent.
This is because the inner pulp, the focus of the treatment, plays an important role in a young tooth’s development. When it first erupts a tooth’s dentin layer, the living tissue that makes up most of the body and roots of the tooth, hasn’t fully formed. The pulp increases the dentin layer over time in conjunction with jaw development.
Because a full root canal treatment removes all of the pulp tissue, it could interrupt any remaining dentin development in a young tooth. This could lead to poorly-formed roots and a less healthy tooth. For an immature permanent tooth, then, we would use variations of a root canal treatment depending on the nature and extent of the injury, the patient’s overall health and medications they may be taking.
Our main objective is to expose or remove as little of the pulp tissue as possible when treating the tooth. If the pulp hasn’t been exposed by the decay or injury, we may only need to remove the softened decayed or injured dentin while leaving harder dentin nearer the pulp intact. If, however, the pulp has become partially exposed by disease or injury, we would then perform a pulpotomy in which we remove only the exposed tissue and then place calcium hydroxide or mineral trioxide aggregate (MTA) to stimulate dentin growth that will eventually patch the exposure site.
In cases where decay or injury has rendered an immature tooth’s pulp tissue unsalvageable, we may use a procedure known as apexification that seals off the open, cylindrical root end of the tooth. This will allow bone-like tissue to grow around the root to serve as added support for the tooth. Although it can save a tooth in the short run, the tooth’s long-term survival chances may be lower.
By using these and other techniques we may be able to save your child’s immature tooth. At the very least, such a technique could postpone replacing the tooth until a more opportune time in adulthood.

Famed educator Maria Montessori once said, “Play is the work of the child”—and most kids take their “work” very seriously. But their avid enthusiasm might also raise the risk of blunt force injuries, particularly to the mouth.
While you should certainly take steps to protect their mouth (like a custom-made guard for contact sports), you can’t completely erase the risk. You should know, therefore, what to do in case of a mouth injury.
The lips, tongue, and other soft oral tissues often get the brunt of any contact injury, ranging from minor bruising and swelling to severe cuts that require medical attention. First, clean the area as thoroughly as possible to remove trapped dirt or debris in the wound. If bleeding occurs, apply continuous gentle pressure with a clean cloth or gauze for 10-15 minutes until it stops, and cold compresses for any swelling. If the wound looks deep or severe, take them to an emergency room.
Blunt force can also impact teeth in a variety of ways. If part of a tooth chips, attempt to find the pieces and see a dentist as soon as possible—they may be able to bond the pieces back to the tooth. If a tooth gets moved out of place, call your dentist immediately or go to an emergency room after hours.
If a permanent tooth gets completely knocked out, find it and rinse off any debris with clean water. Then, place it gently back into its socket, or alternatively between the child’s cheek and gum or in a glass of cold milk. You’ll need to see a dentist as soon as possible to have the tooth replanted. With this kind of injury, time is of the essence.
A hard impact can also fracture the jawbone, which may be suspected if the face appears distorted or the teeth can’t make contact with each other when the jaws are shut. Control any bleeding, apply cold compresses or mild pain relievers to ease any pain or swelling, and go to an emergency room immediately.
A traumatic injury can heighten everyone’s emotions, including yours. You can avoid your emotions turning into panic, though, by following these common sense guidelines to help your child get through this unfortunate event.
Contrary to what you might think, a knocked out tooth doesn’t inevitably mean tooth loss. Time is of the essence — the shorter the interval between injury and replanting the tooth, the better the tooth’s long-term survival. The longer the interval, on the other hand, the less likely the tooth can survive beyond a few years. That phenomenon is due to the mouth’s natural mechanism for holding teeth in place.
The tooth root maintains its attachment with the jaw bone through an intermediary tissue known as the periodontal ligament. Tiny fibers from one side of the ligament securely attach to the tooth root, while similar fibers attach to the bone on the opposite side of the ligament. This maintains stability between the teeth and bone while still allowing incremental tooth movement in response to mouth changes like tooth wear.
While the ligament fibers will attempt to reattach to a replanted tooth’s root, the longer the tooth is out of the socket the less likely the fibers will fully reattach. An “ankylosis” may instead form, in which the root attaches directly to the jaw bone without the periodontal ligament. In this situation the body no longer “recognizes” the tooth and begins to treat it like a foreign substance. In all but the rarest cases, the tooth root will begin to resorb (dissolve); at some point (which varies from patient to patient) the attachment becomes too weak for the tooth to remain in place and is lost.
Ideally, a knocked out tooth should be replanted within 5 minutes of the injury (for step-by-step instructions, refer to The Field-Side Guide to Dental Injuries available on-line at www.deardoctor.com/dental-injuries). Even if you pass the 5-minute window, however, it’s still advisable to attempt replanting. With a subsequent root canal treatment (to remove dead tissue from the inner tooth pulp and seal it from infection), it’s possible the tooth can survive for at least a few years, plenty of time to plan for a dental implant or similar tooth replacement.
