PHOENIX, Ariz. — A dental hygienist in Phoenix noticed something strange in the mouths of her patients — and spoke up about it.

Now a toothpaste manufacturer is taking action, according to KNXV.

Trish Walraven has seen lots of things as a dental hygienist, but until a few years ago, she had never seen anything like this.

“We thought it was a cleaning product or something that people were chewing,” Walraven said.

They were little blue dots trapped in the tiny spaces between people’s teeth and gums.

“Some weeks I’ll see five or six patients,” Walraven told KNXV.

Walvaren started asking around and other hygienists were seeing the blue dots, too.

It took awhile, but they finally figured out what it was — polyethylene.

It’s  a plastic used in all kinds of things like garbage containers, grocery bags, bullet proof vests, even knee replacements … and now in toothpaste.
