Did pain in your head start after completing root canal or was it present before the treatment?.you might experience referred pain in head due to toothache or sometimes it may also be due to sinusitis.if your pain hasn't reduced after 20 days of treatment i would not recommend you to go ahead with cap. Please get a thorough examination done of your other teeth as well to rule out any possibility of infection in other teeth.
