Endodontic Retreatment
With the appropriate care, your teeth that have had endodontic treatment will last as long as other natural teeth. Yet, a tooth that has received treatment may fail to heal or pain may continue to exist. Sometimes, the pain may occur months or years after treatment. If so, Endodontic Retreatment may be needed.
Improper healing may be caused by:
- Curved or narrow canals that were not treated during the initial treatment.
- Complicated canals that went undetected during the initial treatment.
- The crown or restoration was not placed within the appropriate amount of time following the procedure.
- The crown or restoration that did not prevent saliva from contaminating the inside of the tooth.

Inflamed Tissue

Filling Removed

Canals Cleaned

Root Material Placed

Filling Restored

Healed Tooth
In some cases, new problems can influence a tooth that was successfully treated:
- New decay can expose a root canal filling material, causing infection.
- A cracked or loose filling or crown can expose the tooth to new infection.
Once retreatment has been selected as a solution to your problem, the doctors will reopen your tooth to gain access to the root canal filling material. This restorative material will be removed to enable access to the root canal. The doctors will now clean your canals and carefully examine the inside of the problematic tooth. Once cleaned, the doctors will fill and seal the canals and place a temporary filling in the tooth.
At this point, you will need to return to your dentist as soon as possible in order to have a new crown or restoration placed on the tooth to restore full functionality.

My regular dentist didn't even ask me how I was feeling the last time I saw him. Dr. Hansen made me feel like he really listened and wanted to HELP me. You know when you watch medical shows and the doctors do everything they can for their patients and you say "That doesn't happen in real life"! Well, Dr. Hansen could have his own show and he would be the one that everyone says "I want THAT doctor!". I've already told my friends about him and have recommended him to everyone! Thank you, Dr. Hansen!!

I was anxious about the procedure, I'd never had a root canal re-treated before, and I'm kind of a nervous person anyway, but everyone was very nice and put me at ease. The procedure was pretty much painless. I had a different tooth that Dr. Christensen performed a root canal on 14 years ago... I still have that tooth and it is still pain free. I wouldn't hesitate to come back if I ever needed to.

If you have to have treatment, this is the best place to get it done. Drove 3 hrs to get there, so happy with the results

This is the second root canal I have had to get in the past few months (different teeth). The staff is great, and I am amazed at the high level of efficiency between the doctor and the dental assistant. Almost nothing needs to be said between them--whatever he needed was already waiting for him when he needed it. I have nothing but kudos for Las Vegas Endodontics.
