Artificial Teeth Goof

I looked through the topics here but none of the titles mention the hilarious fake werewolf teeth that Samaire Armstrong wore in the bathtub scene. For anyone who needs it pointed out, she partially sits up in the tub with her goofy fake teeth clenched shut and then opens her mouth... but the fake teeth stay clenched, thus comically exposing her own upper row. Then in a following shot of her writhing in the tub you can clearly see the still clenched fake werewolf teeth partially receded into her mouth with both rows of her real teeth visible around it.

Here's a link to a shot where you can see the fake's upper gums:

Did no one else notice this hilariousness?
