1. Triclosan
Triclosan is used in skin care products, deodorants, laundry detergents, mattresses, toilet fixtures, hand sanitizers, toothpaste, and more. This chemical has powerful antibacterial and antifungal properties, but it’s also been linked to numerous health problems. Triclosan impedes the thyroid gland, is likely an endocrine disruptor, and it may cause cancer. Triclosan is used in some of the most popular toothpastes.
2. Sodium Lauryl Sulfate
A common ingredient in toothpaste and another likely cancer contributor, sodium lauryl sulfate (SLS) is as a surfactant that helps thicken toothpaste, and is responsible for its foaming action. SLS is said to help dissolve dental plaque. It is a known skin irritant, it pollutes our groundwater, it is toxic to fish and other aquatic animals, and it’s a pesticide and herbicide that is used to kill plants and insects.

3. Aspartame, Saccharine
These are artificial sweeteners that often show up in toothpaste formulas and many sugar free foods. Each has been linked to many serious health problems and should be avoided altogether.
4. Fluoride
Fluoride is an endocrine disrupter that calcifies the penile gland, and can reduce thyroid and adrenal gland function. Fluoride increases cancer risk, causes damage to DNA, inactivates enzymes within the body, accelerates aging, disrupts the immune system, and should be avoided both in toothpaste and in water.
5. Propylene Glycol
Propylene glycol is a form of mineral oil. It’s an alcohol that is produced by fermentation of yeast with certain carbohydrates.
6. Glycerin
In itself, glycerin is not toxic. The problem is that glycerin, when scrubbed onto the surface of teeth, leaves a residue that is hard to remove. You can rinse your mouth two to three dozen times to remove it.
7. Diethanolamine
Diethanolamine (DEA), is in products that foam like toothpaste. DEA disrupts hormones and forms cancer-causing nitrates. Dr. Samuel Epstein, professor of environmental health at University of Illinois, states that repeated exposure to skin may lead to increased risk of liver and kidney cancers.
8. Sorbitol
Sorbitol is used as a thickener and a humectant to prevent toothpaste from hardening when the tube is opened or when the toothpaste is exposed to air. Sorbitol is a sugar alcohol (similar to xylitol) used to sweeten some “health food” products. Some researchers have recently discovered that sorbitol found in chewing gum can cause chronic diarrhea. Very little research has been done on this chemical.
9. Microbeads
If polypropylene, poly-e-terephthalate, and polymethyl methacrylateis are tiny pieces of plastic that are included in toothpaste as an abrasive. While these little plastic beads may help scrub plaque off your teeth, they also damage tooth enamel and become lodged in sensitive gum tissue. To make matters worse, they absorb both bacteria and industrial chemicals and are believed to be endocrine disrupters.
Conclusion
Don’t buy the brands with the aforementioned ingredients. A brand with any of the ingredients listed should not be a brand you trust. Try an all-natural toothpaste powder; you may find you love it like many others have. Or just make your own! Here’s a super easy recipe:
- Equal parts of coconut oil and baking soda
- Add essential oil to taste (I like peppermint)
- Add stevia (if desired) to taste
- Add a pinch of unrefined sea salt for a boost of minerals
