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 should be a red, blue, green, or black square which talk about the quality of the toothpaste. This is what the colors signify:
Green Stripe – The color that represents toothpaste made with natural components
Blue Stripe – This color means that the toothpaste contains some kind of medicinal additions
Red Stripe – This color means that the toothpaste has natural components with chemical additions
Black stripe – This means that the toothpaste is made of nothing but chemical constitutes
It is crucial for your health to preserve the health of your teeth, thus next time you purchase a toothpaste pay attention to the color of the square. If it is anything but green, then return it immediately. If you don’t want to open them there, you can ask an employee to help you with this. Blue square is OK, but the green is priority. In just the first week of usage you will notice a change. Your gums and teeth will be grateful.
