When you brush your teeth, the last thing you'd expect to hear is that you could be doing damage to them.

But if you use Crest toothpaste, that could be the case.

A few years ago, dental hygienist Trish Walraven started seeing small blue specs in the gum lines of her patients. She asked around, and others were seeing it, too.

Those little blue specs are polyethylene, a plastic used in the manufacturing of things like grocery bags, bulletproof vests and knee replacements.

And it has been revealed that same product is used in Crest toothpaste.

Procter & Gamble, the makers of Crest, released a statement saying it has received many requests for polyethylene to be removed from their product. The company said it will do so.

Wait, so people have to REQUEST that companies don't use PLASTIC in their products that are used orally?
