Can a Root Canal Be Accessed from the Side?

Root canal treatment is a common dental procedure designed to address infected or inflamed pulp tissues within a tooth. Traditionally, the treatment involves accessing the pulp chamber from the top of the tooth, which is often covered by a crown. But can this process be done from the side, instead?

Standard Access Route

During a conventional root canal treatment, dentists typically access the tooth's pulp chamber by drilling through the crown or the visible portion of the tooth above the gum line. This method is widely accepted and has a high success rate. However, there are situations where an alternative access point may be considered, especially if the crown is already in place.

Alternative Access Points

While not standard, in some cases, a dentist might consider using an alternative access point on the side of the tooth if the top of the tooth is not feasible. This approach might be considered in the following scenarios:

Previous Access Problems: If there are complications or difficulties with the original access site, a side access might be used to provide a clearer path. Retreatment: If a previous root canal treatment has failed and requires retreatment, a side access could be a viable option. Anatomical Considerations: Certain tooth anatomies might allow for a more favorable side access point.

However, accessing a root canal from the side can complicate the procedure and may not provide the best outcome. It is crucial to consult with an endodontist, a specialist in root canal treatments, to determine the best approach for your specific situation.

Myth: Root Canal Must Be Done from the Top of the Tooth

Some people believe that a root canal can only be done from the top of the tooth. While it is true that introducing instruments to access the root canals typically requires drilling through the crown from the top, this is the standard method for several reasons:

The pulp canals of the tooth are located within the roots, and vertical access from the top is necessary to reach these areas effectively. Vertically introduced instruments are less likely to break or become dislodged in the tooth. Bending the instruments 90 degrees is not practical and could lead to damage or breakage.

It is important to note that the new crown does not necessarily have to be replaced, unless it fractures during the procedure or there is recurrent decay beneath it. In some cases, the crown can be temporarily removed to perform the root canal, and then re-crowned if necessary.

"If you do not want to risk damaging your crown during a root canal, you can ask your dentist to remove the crown before the procedure. After the root canal is completed and everything is fine underneath the tooth, the same crown can be re-attached."

Conclusion

While root canal treatments can be done from the side in certain specific scenarios, standard practice generally involves accessing the tooth from the top. This method provides the best outcome and minimizes risks. Always consult with a dental professional to discuss the best course of action for your individual case.
