Toothpaste with a green stripe
: The green stripe on the toothpaste tube can mean that the toothpaste is all-natural. “All-natural” means that the toothpaste does not contain synthetic chemicals, medications, or bleaching agents.
Toothpaste with blue stripes may indicate a combination of natural toothpaste and added medication. “Added medication” refers to toothpaste that may contain bleaching agents or certain types of pain relievers.
The worst thing of all:
The worst color you want to see on your toothpaste tube is a black stripe. A black stripe indicates that the toothpaste is made with 100% synthetic chemicals. This is not something you want to consume every day.
