Root canal treatment is needed once the inner nerve of the tooth becomes affected by decay or infection. In this instance, the tooth may be very sensitive to pressure or temperature, and this can result in intense pain. In the initial stages of decay or infection, symptoms may not appear immediately. But, in the advanced stages an abscess (spot-like inflammation on the gums) will appear.
To address this type of decay or infection, the patient has two options: extract the affected tooth or save the tooth via root canal therapy. However it should be noted that when extracting a decayed or infected tooth, this can lead to significant and expensive dental issues for adjacent teeth. Therefore an extraction may lead to greater problems. Root canal therapy is therefore a more desirable option, due to the provision of full functionality to the tooth and mouth. And in addition this will not cause any future problems with neighbouring teeth.
The reasons a dentist will recommend root canal therapy include the following:
• Decay has reached the tooth pulp (the living tissue inside the tooth)
• Development of infection or abscess inside the tooth or at the root tip
• Trauma or injury to the tooth
Thanks to the restoration root canal therapy provides, the benefits will usually last a lifetime. You will benefit from full functionality of your tooth and mouth. In future it may be necessary to retreat the tooth, but this would only be required if a new, separate infection was apparent.
