###Human: I have extreme pain in the root canal treated tooth. Will I lose my tooth? ###Assistant: Hi. Root canal treatment involves three main steps namely: Temporary filling which you mean is just the superficial one. Pain may persist after the first two steps and before completion of the third step. The pain might be due to: The above-mentioned pain will disappear soon after the third step, once the remnants are removed and the infection subsides. As of now, do not bite on any hard food substance with the treated tooth. In case the pain remains even after the root canal filling is done, then re-root canal treatment might be needed after seeing the x-ray. There are various methods to save the tooth and hence you may not require extraction of the tooth. For follow up, kindly attach pictures of the treated tooth and also the pre and postoperative x-rays and consult a dentist online -->
