The secret of the colored line on a toothpaste tube.
The use of toothpaste is essential for maintaining oral health, preventing tooth decay, and combating bad breath. There are many brands available to meet different needs. Have you ever seen a colored line on a toothpaste tube? Here’s what each color usually means:

Red band: A toothpaste with a red stripe usually means a formula that combines natural and synthetic ingredients. It is recommended to minimize exposure to unnecessary chemicals in daily life.

Green stripe: A green stripe on the toothpaste packaging means that it is made primarily from natural ingredients. This means that the toothpaste does not contain artificial chemicals, medications, or bleaching agents.

Blue stripe: A toothpaste with a blue stripe usually indicates that it is a mixture of natural toothpaste with the addition of medicinal ingredients, such as whitening agents or specific pain relievers.
