Unfortunate for us, some toothpaste brands labeled as natural often contain ingredients that are harmful to us and our environment. Let's brush up on a few traditional toothpaste and natural toothpaste ingredients.
Toxins in Popular Toothpaste Brands:
Carbomer: Synthetic polymer. Can be contaminated with benzene, a known carcinogen, during the manufacturing process. May cause mild skin irritation or allergic reaction. Classified as a microplastic, meaning it's not biodegradable and will persist for a very long time. Microplastics themselves are not considered toxic but can affect health due to the chemicals they contain and absorb.
Carrageenan: Thickening agent found in very popular natural toothpaste brands. Found by scientists to be linked to bloating, gastrointestinal inflammation and ulcerations, irritable bowel disease, and colon cancer.
DEA: Petrochemical derivative used in antifreeze and brake fluid. Found in household items including toothpaste. There are concerns that DEA may be a carcinogen and a hormone disruptor. It also reacts with other ingredients to form nitrosamines which are carcinogenic and genotoxic (damage DNA).
Dyes: Petroleum and coal tar derived carcinogens often contaminated with arsenic and lead. Persistently used in household items and cosmetics like toothpaste. Blue 1, Yellow 10, and Red 30, are the most common in toothpaste.
Ethoxylated Ingredients (e.g., SLES, Polysorbate, Polyethylene Glycol): The ethoxylation process creates 1,4-dioxane and ethylene oxide, known human carcinogens. Ethoxylated ingredients can contain trace amounts of these harmful byproducts. Some ethoxylated compounds are harmful to aquatic life and are persistent in the environment.
Fluoride: There is a plethora of research on fluoride, on both sides of the argument, whether or not it's a toxin in toothpaste. It has been found by experts, including EPA officials, to be a neurotoxin, meaning it can damage the brain and nervous system and cause neurological disorders. Studies indicate that it can cross the blood-brain barrier, impacting cognitive function. Some studies suggest that the neurotoxic effects of chronic fluoride exposure could decrease cognitive development and increase ADHD prevalence.
SLS: Petroleum-based detergent used as a foaming agent. Found in popular natural toothpaste and traditional toothpaste brands. Skin, eye, and respiratory tract irritant that exacerbates mouth ulcers and chapped lips.
Titanium Dioxide: Coloring agent used in both natural toothpaste and traditional toothpaste to give the paste a bright white color. It has been found that nanoparticles of this ingredient can enter the gums and have toxic effects on the central nervous system.
Worth Noting:
Charcoal Powder: Due to its abrasive particles, charcoal may lead to enamel erosion, tooth sensitivity, increased risk of cavities, and gum irritation. Discoloration and staining can occur if charcoal particles work their way into enamel.
Sodium Bicarbonate (baking soda) and silica/hydrated silica: Not necessarily toxic but popular in natural toothpaste brands. Found to be too abrasive for tooth enamel. Potentially wears down enamel and prevents re-mineralization opening the door for discoloration, stains, and irreparable damage.
Xanthan Gum: Stabilizing and thickening agent found in popular natural toothpaste brands. Used to create a desirable consistency and bind ingredients. Known to cause gas and bloating.

Rod-shaped Nano Hydroxyapatite
Has a better safety profile than needle shaped. It is more commonly used in dental products and has been shown to reduce sensitivity and strengthen enamel.
Xylitol, Sorbitol, and Erythritol (artificial sweeteners)
Ingredients that I'd rather not see. Having said that, I confirmed with the founder of Canary that negligible amounts are used in their tablets, and they are always looking to evolve their products and ingredients as science and research allows.
