Ok, first of all, fix up your spelling. I cannot understand you properly.
What do you mean by that shaving her face?
That sounds strange and...weird. Girls don't shave their faces, but when I googled it, it turns they actually do. But, we usually don't do that really, instead we use cream or waxing. Btw, you sound like you are bothering with her looks. If you are so concerned about it, why don't you gently talk to her.
Facial hair indicate undegoing puberty. Your teeth are different from hers because you are male, therefore you shouldn't be worry about her teeth, for goodness sake.
