Feeding milk with bottle during infancy is common. During bottle feeding the milk is drawn by child by sucking (-ve pressure) by constriction of cheek muscles. The nipple of the bottle is an artificial one which does not have the sense of touch and response. So the whole milk is dawn by negative pressure alone( in case of breast feeding, the mother ejaculate milk by touch sense response; so child need not exert more sucking pressure). This negative pressure will try to constrict the widening upper jaw. But the general tongue movements will counter it to the maximum.
After four (4)Yrs the upper teeth start erupting in to the oral cavity. They erupt like landing aeroplane- from back to front in a downward and forward direction with more force. If the child continues the bottle feeding at this time, the contracting force of cheek muscles and natural tooth eruption force will push all the upper front teeth forward resulting in forwardly positioned, spaced front teeth with 'v' shaped upper arch!!
