Root Canal Retreatment Rancho Bernardo
In rare cases, root canal therapy fails to work as expected. The treated tooth might not heal properly, or a patient might experience post-surgical complications that jeopardize the tooth. Root canal retreatment involves the removal of the previous crown and packing material, cleansing the root canals, and re-packing and re-crowning of the tooth. In short, root canal retreatment is almost identical to the original procedure, aside from the structural removal. The success rate for a root canal retreatment runs at around 75%.
Root canal treatments and retreatments are a better alternative than extraction for most individuals. If a tooth has good bone support, a solid surface and healthy gums beneath it, it stands a good chance of being saved. Opting for root canal retreatment can be far less expensive than the alternatives. Dental implants, extensive bridgework, and the creation of aesthetically pleasing prosthetic teeth cost far more than working with the natural tooth. They also require maintenance and feel less natural than a “real” tooth.
Why is root canal retreatment required?
Though the prospect of more endodontic surgery might not be pleasant, root canal retreatment is fairly simple. In general, the whole treatment can be completed in 1-3 visits.
There are a number of reasons why root canal therapy unexpectedly fails, including:
- Cracked crown leaking filling material.
- Curved or narrow canals not treated during the original procedure.
- Delay in the placement of restorative devices following the procedure.
- New decay to the tooth.
- New fracture in the treated tooth.
- Saliva entering the restorative structure.
- Undetected complex canal structures.
What does root canal retreatment involve?
On the day of the retreatment procedure, a local anesthetic will be administered unless another type of anesthetic has been selected. The affected tooth is isolated with a rubber dam. The dam protects the tooth during treatment from bacteria and saliva. The amount the dentist can do within a single appointment will much depend on the amount of inflammation present, and the complexity of the treatment.
The first step in a root canal retreatment is to gain access to the inner tooth. If a crown and post have been placed, these will be removed.
Next, filling material and obstructions that block the root canals will be removed. This removal is conducted using an ultrasonic handpiece. The advantage of using this tool is that any unwanted material is vibrated loose. Tiny instruments will then be used to clean and reshape the root canals. X-rays may be taken to ensure that the roots are thoroughly clean. If this part of the treatment proves to be complex, medicated packing material will be applied, and the rest of the cleansing procedure will be done at the next visit.
When the dentist is confident that the root canals are completely clean, gutta-percha is used to pack the space. This rubbery material seals the canals to prevent bacterial invasion. Finally, a temporary crown or filling is applied to tooth. At a later date, the color-matched permanent crown will be placed.
If you have any questions or concerns about root canal retreatment, please ask your dentist.
Excellent Rancho Bernardo dentist. I've been seeing him for about five years and couldn't be happier. I drive out of my way to see him and he's always worth the trip. I've never had a painful experience in his office and I suffer from extreme dental phobia. My family see him as well. I recommend him to everyone. You won't be disappointed.he best to me. Highly recommended!
The first time I went here I was a little nervous seeing a new dentist. But from the second I walked in the staff put me at ease. They were very nice and knowledgeable. Even more than that Dr. Reza was the best dentist I have been to. He was gentle when checking over my teeth and made me feel a lot more comfortable. The appointment was also prompt, which I always like. Overall my cleaning was the best experience I've had at any dentist.My entire family has been coming to Dr. Hekmat for over 15 years. He is the best dentist hands down! He is gentle and understanding of my phobia of dentists. He and his staff work well together. It is easy to get an appointment for what ever dental issue arises.
Dr. Hekmat and all of his staff are gentle and friendly. They take the fear out of going to the dentist. He has done quality work on my teeth for the last three years and fixed problems I had from previous, poor quality dental work too! I am more than willing to drive 40 miles from where I live because I've never had such a great dental experience anywhere else! !
