In order to inspect our hypothesis that stress concentration is closely related to the cause of dental caries, the finite element structural analyses of tooth and periodontium were carried out. The possibility of the correlation of stress concentration and wedge-shaped defect, periodontopathy and eminence of alveolar bone became clear. Then, contact problem analysis of adjoining teeth or upper and lower teeth were carried out. It became clear that the origin of dental caries is a stress concentration zone. This stress concentration point is similar to actual growth point of caries. Furthermore, it was clarified that there was a correlation of stress concentration and attrition, fissure-pit caries and secondary dentine.
