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.

You might think David Copperfield leads a charmed life:Â He can escape from ropes, chains, and prison cells, make a Learjet or a railroad car disappear, and even appear to fly above the stage. But the illustrious illusionist will be the first to admit that making all that magic takes a lot of hard work. And he recently told Dear Doctor magazine that his brilliant smile has benefitted from plenty of behind-the-scenes dental work as well.
“When I was a kid, I had every kind of [treatment]. I had braces, I had headgear, I had rubber bands, and a retainer afterward,” Copperfield said. And then, just when his orthodontic treatment was finally complete, disaster struck. “I was at a mall, running down this concrete alleyway, and there was a little ledge… and I went BOOM!”
Copperfield’s two front teeth were badly injured by the impact. “My front teeth became nice little points,” he said. Yet, although they had lost a great deal of their structure, his dentist was able to restore those damaged teeth in a very natural-looking way. What kind of “magic” did the dentist use?
In Copperfield’s case, the teeth were repaired using crown restorations. Crowns (also called caps) are suitable when a tooth has lost part of its visible structure, but still has healthy roots beneath the gum line. To perform a crown restoration, the first step is to make a precise model of your teeth, often called an impression. This allows a replacement for the visible part of the tooth to be fabricated, and ensures it will fit precisely into your smile. In its exact shape and shade, a well-made crown matches your natural teeth so well that it’s virtually impossible to tell them apart. Subsequently, the crown restoration is permanently attached to the damaged tooth.
There’s a blend of technology and art in making high quality crowns — just as there is in some stage-crafted illusions. But the difference is that the replacement tooth is not just an illusion: It looks, functions and “feels” like your natural teeth… and with proper care it can last for many years to come.Â Besides crowns, there are several other types of tooth restorations that are suitable in different situations. We can recommend the right kind of “magic” for you.
