Root Canal Therapy

Just about each and every one of us can conjure up a memory of a friend, acquaintance or family member that has had a horrible experience at a dentist, most likely during a root canal procedure.  The fact of the matter is that root canal's are the most common procedure in endodontics, and advances in the dental world have made the once feared procedure a completely different experience!  In today's day and age, having a root canal performed causes little to no discomfort to our patients.  

When a tooth becomes infected, the infection is usually related to the nerves that exist in the roots of the tooth.  It is important to remove the infected nerves because left untreated, the infection can turn into an abscess which can lead to bone loss and even sepsis.  The procedure begins with the dentist drilling into the tooth to create an opening in the canal, in which the nerve resides.  The dentist can then remove the infected tissue, clean the canal, and fill the canal with a sealant called gutta percha. After the root canal is complete, the dentist may or may not recommend a crown to better preserve the tooth for years to come. 

Should you need a crown, the good news is Norbo Dental can (in most circumstances) make the crown in a single day! To learn more, visit our same day dentistry page, or call our office at 540-338-7325 to speak to one of our team members.


Root canal procedures are not always successful and circumstances may cause a recurring infection in the root to occur. When this happens, your dentist may recommend an apicoectomy, which is a procedure in which the root of the tooth is removed and replaced with a filling. In most cased a second root canal, or retreatment is considered before moving forward with an apicoectomy due to the fact that it is a slightly more complicated procedure.


When cared for properly, most teeth with root canals can last as long as any other natural tooth. There are times when a tooth that has had a root canal fails to heal, or the tooth becomes painful or diseased months or years after a successful root canal. It is in these situations that a re treatment may be recommended by your dentist.

Why do I need retreatment?

As with any medical or dental procedure, 100% success is never guaranteed or realistic.  A failed root canal procedure can occur because of:

  • Narrow or curved canals that were missed during the root canal procedure
  • Complicated canal anatomy that was missed during the procedure
  • Patient delaying final restoration of tooth with  recommended crown or other procedure
  • Salivary contamination inside of the tooth

In other cases, a new problem can jeopardize a tooth that was successfully treated.  New decay can expose the root canal filling material to bacteria, causing a new infection in the tooth. A loose, cracked or broken crown or filling can expose the tooth to a new infection. A tooth sustains a fracture. 

What does the procedure involve?

Retreatment is very similar to a traditional root canal.  During the procedure the canals are opened so that the dentist has access to the root anal filling material, which is removed and the canal is cleaned.  After cleaning the canal the canal is refilled and the tooth is re-restored with most commonly a crown. 

Retreatment is not always as successful as the initial root canal procedure and therefore in some situations your dentist may discuss success rates of re treatment with you to determine if it is worthwhile pursuing, or if it may be better to consider extracting the tooth instead.  Either way, our dentists are here to help you every step of the way!
