If the tooth is paining then there may be a need for root canal. Otherwise you may not need. The final treatment will be decided only after checking the tooth

The requirement of root canal treatment will be based on the amount of dentin or pulp exposure present clinically. A clinical photograph of the tooth and an x-ray will be the tools for making the appropriate diagnosis. Whether it is a front tooth or a back tooth and whether the trauma which broke the tooth has also caused any bone damage are the other questions that need to be answered. Please consult a dentist for a proper clinical check up so that the appropriate treatment options can be explained to you. Regards.
