What is this treatment?
Deep decay, cracks or trauma can inflame the inner tissue of the tooth. Symptoms can include sensitivity to hot and cold, spontaneous pain or swelling of the gum.
During treatment the inflamed tissue is removed, the root canals are shaped and disinfected and filled with a special material. This allows the tooth to stay in the mouth instead of being extracted.
Teeth with root canal treatment can become weaker, so they are usually strengthened afterwards with a large filling or a crown.
