When treating pulpitis, it is best to take oral x-rays if possible. This is because taking oral x-rays can help the doctor and the patient to better understand the pulp of the mouth, as well as the specifics of the inflammation and infection within the root canals, and after understanding the situation, it can help to have a better treatment for endodontitis. After treatment, radiographs can also be taken to better understand the infected material in the root canal and whether the inflammation has been completely removed, which can prevent further infection and pain, and prevent the occurrence of apical periodontitis. However, if some places are limited by the conditions and do not have the conditions to take X-rays, as long as the doctor has enough experience and good technology, taking dental films is not necessary. But you must go to a regular dental clinic to get better treatment for endodontitis.
