They have nothing to do with the ingredients in toothpaste.
Why the myth spread
The idea stuck with me because it seems logical.
People want quick ways to identify natural or safe products, and a simple color code seems like an easy shortcut. But in reality, toothpaste formulas are much more complex and can’t be summarized by a single color code.
How to really choose the right toothpaste
Instead of relying on the color of the tube, here’s what really matters:
Check the ingredients
Look at the label on the back. It tells you exactly what’s inside.
Look for fluoride
Fluoride is one of the most effective ingredients for preventing tooth decay and strengthening enamel.
Consider your needs
The different formulas serve different purposes:
Relief from sensitivity
Whitening
Gum care
Natural or low-chemical options
Ask your dentist
