Pain after root canal treatment a month later can be caused by several reasons. It might be due to incomplete removal of infected pulp, or there could be a problem with the filling material. In some cases, a new infection might have developed. If you experience pain, it is important to contact your dentist as soon as possible. They will examine your tooth and may take X-rays to determine the cause of the pain. Depending on the situation, further treatment may be required, such as adjusting the filling or performing additional root canal procedures.
