Patients typically don't feel pain after a root canal, but they may experience tooth discomfort and sensitivity, as stated by WebMD. Patients can usually relieve the discomfort with an over-the-counter pain reliever, such as ibuprofen.
Natural tissue inflammation may cause sensitivity in the affected tooth after a root canal. Patients may also experience minor pain and discomfort, but these effects usually don't impact normal daily activities. To avoid contamination and tooth breakage after a root canal, it is best for patients to minimize chewing with the affected tooth until a permanent filling and crown is put in place, according to WebMD.
