Had root canal 4 day ago. hurt to chew on that side. normal? rt lower wisdom tooth--endodontist. had wicked roots! he saved crown over tooth. wait?

Need to be patient: You need to give it a little time (sometimes a week or more). The nerves in the tooth are gone, but the nerves in the bone are still inflammed. Root canal therapy attempts to repair a really, really sick tooth... Give it a chance to heal. Feel better soon.

Root canal: It is not unusual for a tooth with a root canal procedure done to be sensitive to chewing for several days, even weeks after treatment. Even though the nerve tissue has been removed, there are still vital nerves surrounding the roots, and there may be some residual inflammation causing your discomfort. Rule of thumb, it should be getting better and not worse. If worsening call the dentist

It's always best to: Call the dentist, or in this case the endodontist, who actually treated you to find out what you should expect, how long to expect it for, and whether or not you should wait it out or come back to have the tooth re-evaluated. Having some discomfort 4 days after treatment is not uncommon but each day should be better than the previous one.
