It is believed that any kind of\xa0deprivation\xa0of\xa0this\xa0activity\xa0will\xa0lead\xa0to\xa0fixation resulting\xa0in\xa0oral habits.\nOral drive theory by Sears and Wise (1960):\nStrength of oral drive is, in part, a function of how long a child continues to feed by sucking. The oral drive is strengthened by prolongation of nursing; this is the\xa0cause and not the frustration of weaning.\nRooting reflex by Benjamin (1962): \nThe rooting reflex is movement of the infant’s head and tongue towards an object touching its cheeks. He\xa0suggested\xa0that,\xa0it\xa0arises\xa0from\xa0the\xa0rooting\xa0and\xa0placing reflexes\xa0common to all mammalian infants during the first 3 months of life.\xa0\nPediatric Dentistry, Principles and Practice / M.S.
