changes to my teeth....

maybe all of you think or feel that this is 'yuck' but i want to show it anyway...  :D...

it start from green cast, then the changes of my teeth is from the bottom right picture, then to the uppermost picture...p/s the half face is for showing the changes to my smile and to my face overall, but since i'm a very shy person, so i crop my face into half... hehe.. :)

i am not satisfied with the picture above cause it is not big enough, and if you have any idea on how to make it big, please tell me... :)
