Mostly people read the labels when purchasing toothpastes, but not too many of them read what it says on the bottom of the package. It actually reveals something that is of crucial significance. It says if the paste has been made of organic or non-organic substances.
There are 4 colors- red, blue, green, or black which indicate the quality of the toothpaste.
BLACK – the toothpaste contains chemicals only
RED – the toothpaste is a combination of chemical and natural substances
BLUE – the toothpaste contains only natural substances
GREEN – the toothpaste is completely organic
It is okay if you even take a paste with a blue square, but make the green one your priority. Put the health of your oral cavity first.
