A root canal treatment or therapy is a procedure where in the pulp of the tooth is removed, cleaned for any abscess residue, disinfected and filled with composite filling. Then it is disinfected, dried, and then filled with composite resin. This is usually used to save a tooth from being extracted. 

The root canal treatment is recommended for many reasons. The dentist might recommend root canals instead of traditional extraction (where the tooth is removed from your gums). Root canals can be costly and should only be used on the teeth that are absolutely necessary. Before any procedure can begin, your dentist will ask you for an x-ray. 

Before you give the x-ray to the dentist, make sure to take it to other dentists so they can help you decide if the root canal is necessary. Root canal therapy can be painful for some patients. These are exaggerations to be honest. It will hurt. But it will only be for a few days. Once the anesthetic starts, you will not feel any pain. During your recovery, your dentist may recommend strong painkillers. 

It is not possible for everyone to have strong teeth. If you ignore the pain, it will only make matters worse. If you refuse to receive the necessary treatment, your productivity and health will be at risk.
