Root canal therapy has long been a common form of treatment in dentistry, but does not always remove all of the infection. There is a fair amount of contention regarding the efficacy of root canal therapy for the treatment of deep infection. Dr. Naranjo is a member of the International Academy of Oral Medicine and Toxicology, and understands the various reasons why dentists and many patients question the validity of this treatment. Performed in the traditional manner, there are definitely issues that can arise from the root canal procedure.

The oral structure contains more than our teeth, gums, and the roots that connect teeth to the jawbone. Spanning from the roots of teeth into the dentin are miles of dentinal tubules, tiny areas to which bacteria can travel from an infected root canal. Conventional root canal therapy focuses on the core of infection, which lies in pulp tissue. The idea behind this common procedure is that all of the infected tissue, nerve, and blood vessels are removed in the root, followed by subsequent cleansing and sealing of the canal. Properly done should fully eradicate infection and destroy any remaining bacteria, but this is simply not the case.

The problem with this ideology is that the natural shape and structure of the tooth’s core, primarily dentinal tubules, make it virtually impossible to destroy bacteria efficiently using a liquid “bleach” solution. The inefficiency of this approach to root canal cleansing leads to ongoing infection beneath the surface, persisting long after the tooth has been restored.

What is root canal therapy? If you have a damaged tooth, root canal therapy may be the best option to preserve it. Watch this video to learn more as Dr. Naranjo explains all about it.

What is root canal therapy?

Hello, I’m Dr. Christopher Naranjo with Greenbelt Dental Health. Today I am going to talk to you about root canal therapy.

Root canal therapy may be utilized to preserve your natural tooth if there isn’t any damage to the internal nerve.

What is the process of root canal therapy?

If you have any lingering or severe tooth pain, maybe it is time for a consultation.

The root canal procedure removes the infected nerve and vasculature inside the tooth along with any bacteria.

The tooth inside is cleaned and sealed to prevent any more bacteria from entering. The question is whether this is a good option for you.

A lot is based on how much tooth structure is left and how long the tooth has been infected. There are miles of tubules within the tooth that can make it very difficult to clean.

What technology is used at Greenbelt Dental Health during root canal therapy?

We use our Carestream 3D scanner to evaluate the root anatomy to know exactly where to clean.

Also, through the Fotona laser in our office and ozone, cleansing can occur throughout the whole tooth leading to a more predictable and successful outcome.

From a preservation standpoint, root canal therapy is a less invasive and traumatic treatment of not having the tooth extracted.

But that doesn’t always mean, is the best option for everyone. It’s very important to me to evaluate each person individually and determine the best course of action based on what you feel comfortable with.

Feel free to give us a call today for more information on root canal therapy.


Dr. Naranjo’s approach to endodontics, which really applies to his overall practice ideology, is aimed at helping his patients keep their natural teeth, and their good health, for a lifetime.

Root canal therapy is performed in select cases after a thorough discussion of the advantages and disadvantages of treatment. Patients learn about viable alternatives, and are provided with details in the manner in which Dr. Naranjo performs successful root canal therapy.

What separates this office from others is the use of the Fotona Laser when doing root canal therapies. With proper technology and diagnostic imaging, a predictable and safe outcome can be achieved. Once the diagnostic imaging is completed, treatment takes place using ozonated water to irrigate the canals after the removal of infected tissue. The ozone water is then left in the canals and stimulated via the Fotona Laser. This allows the rapid formation of vapor bubbles, inducing turbulent fluid movements throughout the whole entire tooth, and increased penetration into the dentinal tubules. The entire root system is dried and then properly sealed to prevent any bacteria from re-entering. The filling materials we use are biocompatible and much safer than previous filling materials. A major advantage of root canal therapy is being able to maintain the natural ligaments around the tooth, which allow compression.

Root canal therapy is not always our preferred method of restorative care. Sometimes, the best treatment choice is removal of the tooth. During the consultation and evaluation, Dr. Naranjo collaborates with each patient to determine suitable treatment based on his or her specific needs.Receive dental care that benefits your general health.
