8 Toxic Ingredients Found in Regular Toothpaste

“Wait, but I don’t ingest toothpaste”, you may be thinking, “so there’s no way the toxins can enter my system, right?”

Actually, wrong.

Toothpaste doesn’t have to be ingested for toxins to enter your system, as they can pass through the lining of your mouth directly into your bloodstream.

And considering that the average adult will use about 20 gallons of toothpaste over their lifetime, these nasty ingredients are something you should avoid.

There are still toothpastes on the market today that contain toxic ingredients. They’ll make all sorts of claims from whitening to strengthening but what they may not tell you is that these ingredients can be seriously unsafe.

 Some of the major offenders are below, but keep in mind that there are other harmful ingredients that we did not list that could be lurking in your toothpaste. It’s very important to do your research and to know what’s in your toothpaste before you use it.


Everyone has heard of fluoride. In fact, approximately 95% of conventional toothpastes sold in the U.S contain fluoride.

In the past, it was drilled into consumers’ heads that fluoride is a must-have because it can strengthen teeth and make them more resistant to tooth decay. However, in recent years there’s been growing concerns over the health risks that fluoride can present, especially in young children. Ingesting too much fluoride can possibly cause permanent tooth discoloration, stomach problems, skin rashes, and impairment in glucose metabolism. In fact, the FDA requires a warning label on every tube of fluoride toothpaste sold in the US.


Fun fact: In 2016, the FDA banned triclosan from soaps, however it’s still allowed in toothpaste. That’s right. It’s banned from a product that we use on our hands, but not from a product that we put into our mouths. Weird, huh?

Triclosan, by definition, is a pesticide, but it’s been used as an antibacterial agent in toothpastes with the claim that it helps fight plaque and gingivitis. Have you ever heard of Agent Orange? You know, the herbicide used in the Vietnam War by the U.S military as part of its herbicidal warfare program?

Well in a crazy turn of events, it turns out that the chemical structure of triclosan closely resembles a major component in Agent Orange. They’re like compound cousins, if you will. And it’s still allowed in toothpaste.

Health concerns associated with triclosan include cancer, weakened heart muscle function, endocrine issues, and bone deformation just to name a few. So why would the FDA allow such a toxic chemical in toothpaste? Well as it turns out, there’s only one brand on the market that still uses Triclosan and coincidentally it’s the same company that convinced the FDA that the benefits of triclosan far outweigh the risks. In fact, this company actually paid for the toxicology studies that the FDA used to decide if triclosan was safe and effective enough for toothpaste. Sounds legit, right?

Now, we’re not going to come right out and say which brand contains triclosan, you can just Google it and see for yourself.


Saccharin is a petroleum-based sugar substitute, AKA lab-produced “sugar” made from crude oil. Ew.

Anyway, we digress. Saccharin is commonly used in diet foods, soft drinks, lip balms, and you guessed it, toothpaste. It’s approximately 350 times sweeter than your run-of-the-mill sugar and falls into the same sweetener category as Acesulfame-K, sucralose, aspartylphenylalanine methyl ester, alitame and tagatose.

Saccharin was linked to cancer in a few clinical studies in the 1970’s but continues to be a commonly used additive in food and hygiene products.


Carrageenan is a common thickening agent in toothpastes – both conventional and natural, that is derived from seaweed.

It can also be found in foods like chocolate milk, yogurt, and cream. Being used in natural foods and toothpastes, doesn’t mean carrageenan is totally safe. It has been shown to potentially cause inflammation in the intestine and possible colon tumors.


Aspartame is used as a sugar substitute and is arguably the most common artificial sweetener used today. The big appeal of aspartame is its use in low-calorie or diet products. Aspartame is about 200 times sweeter than sugar therefore much less of it can be used to achieve the same level of sweetness, in turn keeping the calories in foods and drinks relatively low.

That sounds great, you say? Because aspartame has been known to metabolize inside your body as both a poisonous wood alcohol and formaldehyde. Yes, formaldehyde. AKA embalming fluid. Yuck. That pretty much sums it up. Yuck.

Now, let’s talk about the side effects. We suggest you grab a snack and get comfortable for this…it’s a pretty long list. Possible side effects could include migraines, dizziness, seizures, nausea, numbness, muscle spasms, weight gain, rashes, depression, fatigue, irritability, insomnia, vision problems, hearing loss, heart palpitations, anxiety, vertigo, memory loss, and, brain tumors, birth defects, and joint pain. Aspartame consumption could potentially lead to illnesses such as Alzheimer’s, Diabetes, Multiple Sclerosis, Epilepsy, Lymphoma, Parkinson’s Disease, and Fibromyalgia.

It’s just terrible.


Parabens are a fairly common additive in cosmetics, and that include toothpastes.

Used as a preservative, these chemicals can mimic the hormone estrogen and can potentially cause cancer, developmental, and reproductive issues. Some of the chemicals to watch out for are: Methylparaben, Ethylparaben, Isobutylparaben, Propylparaben, Butylparaben, Isopropylparaben, Benzylparaben.


You know what’s a great idea? Adding a potentially ulcer-causing chemical to your toothpaste to make it foam. Because, as everyone knows, the more foam there is, the cleaner the teeth will be.

Uh, I’m sorry to disappoint you, but foam doesn’t actually clean your teeth. Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) are surfactants that are used in a range of products from industrial cleaners to toothpastes and their main purpose is to provide a foaming lather. The problem with SLS and SLES is that they may cause canker sores, mouth ulcers, stomach issues, and cancer.


Propylene Glycol is a mineral oil that is used in antifreeze, paints, enamels, and airplane deicers in the industrial grade. So just in case your teeth freeze over, propylene glycol got you covered.

In all seriousness, the pharmaceutical grade would be used in toothpastes to smooth out the texture. Unfortunately, it could also possibly cause cancer, reproductive issues, and skin irritation.

We hope we haven’t given you toothpaste induced nightmares, but you can sleep easy knowing that our organic toothpastes are completely free from all chemicals, pesticides, GMOs, glutens, fluoride, saccharin, SLS, SLES, carrageenan, parabens, triclosan, artificial sweeteners or additives, propylene glycol, detergents, or synthetics of any kind.

And if you are ready to get rid of the toxins for good, there’s a brand you can trust. At RADIUS,  we believe that a truly healthy mouth is the source of a bright smile. To keep people healthy, we keep chemicals that cause harm out of our products.

With RADIUS, you can rest assured it is safe and comes from real ingredients that have been naturally grown.
