                                                          This could be from a number of factors. You might be lacking the appropriate amount of calcium to keep the bones strong. This could also be caused by having a disease, such as periodontal disease, gingivitis, or any other kind of gum disease. These diseases cause the tooth to begin to rot, then chip off or break.
