Root canal pain

If caries tissue is already located in the deep dentin, that is, deep caries, then deep caries may accidentally penetrate the pulp when caries is removed, so root canal treatment is needed, it is also possible that deep caries has led to pulpitis or deep caries has led to pulp necrosis, or deep caries has led to apical inflammation. Root canal treatment is needed for caries removal in these cases. If the pulp is vital, then root canal treatment requires local anesthesia, root canal treatment under local anesthesia is not obvious pain. If the pulp is dead, there is no vitality, then root canal treatment basically does not show pain.
