The calcifications you speak of, sounds like dental calculus. If you had excessive dental calculus, I think there is a possibility that you might have periodontal disease. Studies have showns that periodontal disease has links with heart and kidney disease, cancer, osteoporosis and in some rare cases appendicitis. Acute appendicitis is very rare though.
If you are indeed one of these cases, I think you need to see a periodontist, so that this can be evaluated and managed.
