Further proof that celebrities are not born, but made: The popularity of porcelain veneers and other cosmetic dentistry has become an overwhelming presence among hot Hollywood stars. Some celebs spend upwards of $1,000 per tooth to keep their pearly whites on the straight and narrow.

So who has the most ridiculous, overly bleached fake teeth? We'll leave that up to you.
