Those little "blue dots" in your toothpaste are not what you think they are. Sure, if you are like me, you always thought they were health cleaning agents....not quite

A recent discovery by a dental hygienist, toothpaste containing a specific ingredient may actually be causing harm.

Fox8 reports that according to Trish Walraven, a dental hygienist in Phoenix, began noticing tiny blue dots trapped in the spaces between the teeth and gums of her patients. After further research and consultation with her colleagues, she discovered that the dots was polyethylene, a plastic with many uses.

In this case, the polyethylene was being used as a microbead and seen primarily in Crest toothpaste. The microbeads were trapping bacteria in the gums and leading to further problems. Crest’s manufacturer, Proctor & Gamble, says the ingredient is “completely safe,” but they are removing it from their toothpaste.

 

If this is something you don't want to put in your mouth, you best bet is to check the ingredient list on the toothpaste box, before buying it. If your toothpaste contains polyethylene, you are putting plastic in your mouth..
