Thanks for ur reply!
Ok, I am 30, and wear that replacement since then. My teeth are not really 'natuarlly' white but rather with slightly yeallow shade (it is very visible esp if I place smthing white to compare the coulour.. That replacement cant be whiter coz, as u understand, it is just it's coulour.
I remember I was reading about OP a while ago in the net.. and , if I am not miostaken, I can use olive oil as well.. Is it correct?.. Sunflower oil??.. I read somewhere that it is not the best choise for best results or it is not really matter?.... Anyway, what is the list of best oils (exept that 'very whitening') which I can choose? Can you PLZ answer?..:)
