Smile makeover, teeth whitening info

While I was looking through a tube of Colgate teeth whitening toothpaste today, I notice many of the teeth whitening ingredients in there. Although I doubt that the toothpaste will whiten teeth, I see some similarity in the product with celebrity sexy teeth ingredients.

These are the celebrity sexy teeth ingredients which is listed in their product packaging :

Propylene Glycol
PVM/MA Copolymer
Hydrogen Peroxide
Flavor
Xylitol
Cetylpyridinium Chloride
Sucralose

I am not too comfortable with the mention of Hydrogen Peroxide. I wonder if the celebrity sexy teeth ingredients with hydrogen peroxide will make the thing taste like floor cleaner or hair dye. Hehehe, these are the common usage of hydrogen peroxide, no?
