Teeth chattering especially during sleep is suggestive of some type of worm infestation with pinworm, hookworm, tapeworm, Tinea saginata, Tinea solium, anchylostomiosis, echinococcus etc. Get stool examined pathologically for ova and cysts for identification of worm and take a full deworming course of treatment from your Physician.
