A little boy is feeling a lot better after doctors removed over 500 teeth removed from his mouth. The 7yearold had complained of swelling on one side of his lower jaw for several years. Upon examination, doctors discovered a large benign tumor. And within that tumor, there were hundreds of small, hard, toothlike structures. The small teeth are sometimes known as odontoids or denticles. The boy's medical condition is called compound composite odontoma, and it is extremely rare.
