A dental ultrasonic tip for removing a post by continuously transmitting ultrasonic energy to the post through continuous contact with the post is provided. The dental ultrasonic tip for removing a post may include a tip body portion, and a post receiving portion integrally formed with a leading end of the tip body portion and configured to include a recess depressed into a predetermined space shape. When a post mounted in a root canal is to be removed, the post is inserted in the recess while coming into contact with an inner surface of the recess. According to the foregoing structure, ultrasonic energy may be continuously transmitted to the post and the post may be efficiently removed.
