In case of damage and/or inflammation of this tissue due to untreated caries, the process of removing the tissue, shaping and cleaning the root canal and then filling the canal with filling materials is called root canal treatment.
Inside the tooth root, there is a vascular-nerve bundle, popularly known as the 'nerve of the tooth', which nourishes the tooth. In case of damage and/or inflammation of this tissue due to untreated caries, the process of removing the tissue, shaping and cleaning the root canal and then filling the canal with filling materials is called root canal treatment. In some cases, laser-assisted treatments can be performed to increase the success of root canal treatment.
Root canal treatment is a treatment performed by numbing the patient's tooth, so it is not a painful procedure. However, some very painful or infected teeth may experience numbness, in which case the tooth can be numbed using advanced numbing methods.
