###Human: I have tooth pain. Should I get root canal treatment for this? ###Assistant: Hello. If you have pain after eating cold or hot, it mostly means that the nerves inside are infected. It has to be root canal treated. If you are so sure that it can be saved and want to try something else, ask a dentist to just clean the cavity and fill it with a temporary filling. Then wait for 2 or 3 weeks and check if there is pain. If you do not have any pain then get it permanently filled.
