Crest and Polyethylene

I use crest and just recently came from the hygienist 3 weeks ago and she found no significant problems, but I'm headed to the store now to by some tooth paste without polyethylene, until I figure out what's going on. Here is why. For all I know the shit could be good for your gums, but I'm not taking any chances.

Polyethylene ain't good for anything that wants to live.

 

Its ridiculous how everything requires research these days. Nothing can be taken for granted.
