I have been using this Crest 3D White toothpaste, and I have to say it works very well. My teeth are pretty damn white, especially since I am a smoker and all.
Yesterday, I took a look at the back of it, and saw the warning label:
Warnings Keep out of reach of children under 6 years of age. If more than used for brushing is accidentally swallowed, get medical help or contact a poison control center right away.
Yeap, that's why Crest 3D White is The Most Serious Mother Fucking Toothpaste On The Planet!
