Even when you just take a quick peek at those pesky (and maybe inspiring for some, to each his own) teeth whitening commercials where the models just magically transform from very shy people to overwhelmingly confident sirens and dashing men all after trying the teeth whitening product that apparently turns it around for them in a complete 180 degrees. Of course, all that is exaggerated but not any less true. You want to stand out as having the prettiest smile or get noticed by people and people do care if you have whiter teeth!
