The 5 Hidden Dangers in Your Toothpaste


Dental hygiene products that you and your children use every day may contain harmful chemicals and toxins that have been linked to a number of serious health risks, especially for young children. Many name-brand toothpastes and mouthwashes contain potentially harmful ingredients, which are made up of very small molecules that may penetrate through the delicate skin membranes of your mouth. The fastest way to get something into your bloodstream is via the skin tissue under your tongue and chemicals can be absorbed directly into the bloodstream through the dense network of blood vessels lining the mucous membrane of the mouth and build up in the liver, kidneys, heart, lungs, and tissues.

Danger 1

Sodium Lauryl Sulphate (SLS) or Laureth Sulfate – A harmful irritant


SLS is added to almost every toothpaste because of its foaming properties. Toothpastes that foam give the impression that the toothpaste is working. It is also used in shampoos. And it’s very very cheap. The journal of the American College of Toxicology reports that SLS can penetrate and be retained in the eye, brain, heart, and liver with potentially harmful long-term effects. SLS is believed to be carcinogenic. SLS is used in laboratories to purposely irritate the skin in order to test creams that heal the skin. It’s said that the percentage cannot be more than 1.5%. Unfortunately, you will never find this information on toothpaste box. Even Vicco – Pure Herbal Toothpaste sold in bio and organic shops has it! It is said, that SLS comes from Indian Coconut Oil. 

(!!!The whole “coconut-derived” or “from coconut oil” or whatever verbiage you see on the label is a marketing gimmick to make you believe that somehow the ingredient is more natural. Don’t fall for it! Choose instead products that have REAL natural ingredients rather than chemicals they’re trying to pass off as “more natural.”!!!) Read more here.







Danger 2

Triclosan: A pesticide

Triclosan is a chemical ingredient found in most toothpastes which is used for its antibacterial properties. Triclosan is a chlorophenol, which is a class of chemicals that is suspected of causing cancer in humans. Taken internally, even in small amounts, this family of chemicals can lead to cold sweats, circulatory collapse, convulsions, coma, and death. On some toothpastes, you will find that after 30 days of usage is recommended to change to another toothpaste. For example, on Lacalut.7269

Danger 3

Propylene Glycol (also called Propanediol): brake fluid


This colourless liquid is the main ingredient in antifreeze, brake fluid, deicers, and laundry detergent, but is also used in most toothpastes and mouthwashes.

It is implicated in contact dermatitis, kidney damage and liver abnormalities. It can inhibit skin cell growth in human tests, can cause gastro-intestinal disturbances, nausea, headache and vomiting, central nervous system depression and can damage cell membranes causing rashes, dry skin and surface damage (according to the FDA Material Safety Data Sheet).



Danger 4

Sodium Fluoride: rat poison


Many people are probably aware that most toothpaste and many mouth rinses contain

fluoride because that’s what dentists have recommended for years to prevent cavities.

Surprisingly, fluoride has NEVER been approved by the FDA. Additionally, a 1990 study

stated that fluoride has been shown to NOT reduce cavities and scientists are now linking

fluoride to dental deformity, arthritis, allergic reactions and about 10,000 unnecessary

deaths each year from cancer. (From “Fluoride an equivocal carcinogen. National Cancer


In children and youth, minimal ingestion of sodium fluoride causes salivation, nausea,

vomiting, epigastric pain, and diarrhea. Large doses of the carcinogen may cause paralysis,

muscular weakness and convulsions, followed by respiratory and cardiac failure.


Danger 5

FD&C Blue Dye 1 & 2: coal tar


Recent studies indicate that FD & C Blue Dyes 1 & 2 can trigger a wide number of behavioral,

learning, and health problems. FD&C colour dyes may also cause potentially severe allergic

reactions, asthma attacks, headaches, nausea, fatigue, nervousness, lack of concentration,

and cancer.

Nowadays, coal tar dyes are synthetically engineered rather than extracted from actual coal

tar, thereby greatly reducing the possibility of being contaminated with carcinogenic

residuals from the coal itself. However, the dyes still contain carcinogenic properties. Over

several decades of use, some of these synthetic dyes have come under greater scientific and

government scrutiny due to their carcinogenic and mutagenic activity. Because of this, they

are still referred to in the industry as “coal tar dyes,” according to the FDA


All those and even more dangerous ingredients are found in three leading toothpaste brands:



Colgate Total Toothpaste





Aquafresh All Tartar Control




Crest 3D White Advanced Vivid Toothpaste





I was really trying to find some safe product on Czech Markete and here you have:


Ayurdent – contains only the best natural ingredients and a high concentration of 17 Ayurvedic herbs. Doesn’t have fluoride or irritating harsh foaming ingredients




Weleda Salt – This is an excellent toothpaste that cleans teeth really well and cares for sensitive gums. It doesn’t foam in a traditional way since it doesn’t contain any chemicals that comercial toothpaste do.6371




And finally something for kids:


Weleda Children’s Tooth Gel – The tooth gel is fluoride free, as well as free of detergents, artifical fragrances, colors and preservatives. Since the only ingredent that is “yellow” (moderate safety) is limonene, I’m pretty confident that it’s safe for kids to use.
