TikTok Conspiracy Theory: Secret Codes on Toothpaste or Manufacturing Mystery?

The colored squares on the bottom of the toothpaste tube have nothing to do with the product’s content.

A bizarre theory spreading like wildfire on TikTok claims hidden messages on toothpaste tubes dictate the product's ingredients. But is this a secret code known only to "elites," or a manufacturing mystery solved by science? Let's separate fact from fiction.

The Viral Claim:

The theory hinges on the small colored squares found on the bottom of toothpaste tubes. According to TikTok users, these squares reveal a secret code:

  • Green: All-natural ingredients
  • Blue: Mix of natural ingredients and medication
  • Red: Natural and chemical ingredients
  • Black: All-chemical ingredients

This supposed code supposedly grants an advantage to the "elites" who understand it, prompting many viewers to question their usual toothpaste choices and scrutinize ingredients like fluoride and foaming agents.

Dentists Debunk the Myth:

This theory, however, is entirely false. Dentists and toothpaste manufacturers are united in debunking this dangerous misinformation. The colored squares simply serve a practical purpose in the manufacturing process.

The Real Reason Behind the Colors:

These squares are merely registration marks used by light sensors at toothpaste factories. Their sole function is to signal the precise location where the tube needs to be cut and sealed, ensuring uniform and consistent packaging. They have absolutely no connection to the toothpaste's ingredients.

Experts Combat Misinformation:

Dental professionals are actively countering this misinformation. Dr. Nate Coughlin, an orthodontist, clarifies that these colored dots are "dyes" used for manufacturing purposes, not ingredient indicators. Dr. Mohammed Adel Habib Taslimi echoes this sentiment, emphasizing that these markings hold no meaning regarding the toothpaste content.

Numerous dental organizations also debunk the theory. Ontario-based Silverhill Dental calls it a "hoax" and advises consumers to disregard these markings when choosing toothpaste. Similarly, toothpaste giant Colgate dismisses the claim as "entirely untrue."

The Fallout of the False Theory:

The theory has unfortunately led many to distrust popular toothpaste brands and seek out "natural" alternatives, often lacking crucial ingredients like fluoride.

Fluoride: Friend, Not Foe:

Fluoride, a crucial ingredient often targeted in the conspiracy, is scientifically proven to prevent tooth decay by strengthening tooth enamel. Concerns about its safety at recommended levels are unfounded. In fact, ingesting a harmful amount of fluoride is highly improbable, as Dr. Coughlin clarifies: a 160-pound person would need to consume an implausible 33 tubes at once to experience any negative effects. The American Dental Association emphasizes that fluoride remains essential for oral health and is mandatory for their approval of any toothpaste.

Other Ingredients Under Scrutiny:

Another ingredient under fire is sodium lauryl sulfate (SLS), a common foaming agent. While some claim it's harmful, there's no credible evidence to support this.

Humor and Alternatives:

The misinformation has sparked humor online, with comments like "I use blue cheese" or "beef liver and honey" on toothpaste. However, creating homemade toothpaste lacking fluoride or containing abrasive substances like baking soda is strongly discouraged by dentists due to potential harm to teeth and gums. Similarly, the American Dental Association finds no evidence of charcoal toothpaste being effective or safe, potentially harming the enamel.


The next time you see a colored square on your toothpaste tube, remember it's a manufacturing mark, not a secret code. When it comes to your oral health, rely on the expertise of dentists and scientific evidence, not unsubstantiated online claims. Always consult your dentist for personalized recommendations on choosing the right toothpaste for your needs.
