Did Laetitia Casta have her teeth fixed?

Many of you are probably familiar with French supermodel-turned-actress Laetitia Casta, some years ago voted most beautiful woman in the world (quite rightly, IMO). One of her peculiarities is that she has less than perfect teeth: in supermodel terms, they’re actually quite ugly. On several occasion, Casta remarked that this didn’t bother her and that she was happy the way god made her (or some such remark).
Yet lately, I have the feeling her teeth are more straight than they used to be. I couldn’t get a cite on this, and it’s hard to find clear pictures of her teeth, but still I get the impression that she had them straightened, somehow. Does anyone know if this is indeed the case?
