    What are the disadvantages of root canal?


    Also known as endodontic therapy, root canal therapy simply refers to a dental treatment in which your dentist or endodontist removes the bacteria infecting the pulp or the nerve chamber of your tooth. Usually, some of the problems that call for root canal treatment include deep tooth decay, chipping of tooth, and trauma to the tooth. Before starting the actual procedure, a local anesthetic is used in order to numb the tooth and the area surrounding it.

    Afterwards, the dentist will use a rubber dam to keep the tooth clean and free from saliva. Once the tooth is numb enough, an opening will be made at the top part of the tooth. With the use of root canal files, the inside of the canals are cleaned and shaped. During this process, a cleaning solution will be used to thoroughly clean all the bacteria in the area. Along the processes, several x-rays will be done in order for your dentist to know what is going on inside the tooth. Finally, root canal filling is done by placing a material, often rubber-like, that fills the entire root canal. A temporary filling will then be placed on the treated tooth. The root canal treatment finally finishes once a crown is placed to make the tooth functional again.

    There are various disadvantages of doing root canal:

    After the treatment, you might feel slightly uncomfortable. Usually, over the counter pain relievers will solve this problem.
    Discoloration and even darkening of the treated tooth is a common con when it comes to root canal therapy.
    If your tooth is not yet restored finally, chewing on the treated tooth should be avoided otherwise, the tooth may crack.
    The treated tooth will not be as strong as its original strength prior to the bacterial infection and the root canal therapy.
    Reinfection may occur if the final restoration is not completed as soon as possible.
    There is a possibility of pieces of shaping file getting stuck inside the root canal.
    Another possibility is that the seal is not good enough due to the shape of the canal.
    A hidden root or extra canal will also demand the treatment to be redone.


    Root Canals are 95% successful for the life time of the patient. Most are done with one visit without the patient feeling anything once the local anesthetic is administered.
