It is only our teeth that helps us to chew food well. the stomach can 't chew the food. without chewing, we can 't digest our food. undigested food can make us ill. thus, each tooth of ours is a friend that helps us to chew our food.Just like your teeth are with you, friends are also with you until care is taken.
