People usually think that children sleep molar is resulted fromthe worms in stomach， but there is no evidence that molar is related with Ascaris or a calcium deficiency. Sleep molar may be caused by a variety of factors， such as emotional factors （such as anxiety， stress， tension）， personality （such as aggressive or hyperactive personality type）， sleep apnea， teeth malocclusion， acid reflux flow， side effects of drugs etc.. Therefore， it is better to regularly consult a dentist （at least once a year）. Adults will also have sleep molar， if it affects others， or the jaw， face， ear pain and other symptoms， one should also be timely to see a doctor.
