Why Do Some Root Canals Fail and What Can Be Done?
Although the success rate of a root canal treatment is high, there are instances when the tooth does not heal as desired. There are several reasons a root canal may fail. One of the main reasons root canal treatment can fail is when the tooth’s canals are not identified and treated, or when they are not completely cleaned. These are problems that can often be corrected with retreatment.
Another way treatment can become compromised is through leakage of salivary bacteria, which can contaminate the treatment area and lead to infection of the root canals and eventually the surrounding bone and gums. This leakage can result from an ill-fitting crown or filling, or from new tooth decay. With poorly sealed root canals, contamination occurs rapidly; in well-sealed root canals, it is effectively slowed or prevented. This problem can also be corrected with retreatment in most cases.
The good news is that a second root canal, or a root canal redo, can usually solve the problem. By carefully evaluating the situation and using advanced imaging techniques, we can pinpoint the source of infection and determine if retreatment is the best course of action. Our ultimate goal is to save your own tooth whenever possible.
What to Expect During Root Canal Retreatment
Root canal retreatment at Forney Family Dentistry & Orthodontics in Forney starts with an evaluation of the existing restoration and the canal fill. Most often, the crown or the existing filling has to be removed to access the inside of the tooth. Any existing posts and cores installed during the initial procedure must also be removed.
After this, the existing material used for the canal fill has to be removed from the canal spaces. The canal spaces are cleaned and reshaped, then disinfected to prevent bacterial growth. At times, a medication may be placed inside the tooth as a temporary measure to prevent bacterial growth before the final procedure.
Finally, the canals are sealed again to prevent future contamination. The final restoration, such as a new crown, should fit well and be vital to the tooth and to the procedure’s success.
Our goal at Forney Family Dentistry & Orthodontics during the second root canal is to restore the tooth, alleviate discomfort, and provide it with the stability it needs for years to come.
