Toxic Ingredients Hiding In Your Toothpaste

Have you ever had a canker sore? Ugh, I have. I’ve had a million of them.

ALWAYS get them whenever I have anything super acidic or really anything citrus. Bummer. I don’t even like to have mimosas because I don’t want to risk it (sometimes tho). I also get them when I’m really stressed (usually when I have a lot going on with work and school).

I started using Tom’s toothpaste when Dylan and I moved in together. He doesn’t like fluoride, so we used Tom’s because it was the only toothpaste at our work that was fluoride free. When I went to the dentist a few months ago, he told me that I needed to start using a toothpaste with fluoride in it. Not wanting to deal with having another cavity, I went to the store and picked up some Crest Pro-Health toothpaste. Not only was it cutting the shit out of my gums, I noticed I kept getting those pesky canker sores. This time, I wasn’t stressed and I wasn’t having any citrus or anything acidic, so what the heck??

Eventually I got one underneath my tongue that hurt SO bad that I could barely talk. I was in so much pain whenever I would eat. I could hardly do anything with my mouth! Whenever I did talk, I talked with a lisp and constantly had to repeat myself. I started to ask myself why I had one so bad when the usual culprits weren’t to blame.


I realized the one thing I changed: my toothpaste. Dylan thought I was crazy. I had to go back to the dentist because one of my fillings was too high and I thought I’d ask him while I was there. He said maybe it was my toothpaste. But he couldn’t be sure.

So, I asked the only other resource that made any sense: Google. Turns out that one of the ingredients that may have been causing the canker sores was SLS, or Sodium Lauryl Sulfate.

Dr. Peter Mann says “a common toothpaste ingredient called sodium lauryl sulfate (SLS) can also cause canker sores.  SLS is a soft tissue irritant that’s also found in shampoo, soaps, and household cleaning products.  Companies use it in toothpaste because it creates foaming action when we brush our teeth.”

As you can assume, I went to the store that day and read through the ingredients of every toothpaste in Target. Almost ALL of the toothpastes had SLS. What the hell!!!??? One of the only ones that I was able to find didn’t have SLS was Sensodyne toothpaste. The only problem: it had fluoride in it. I bought it anyway because I just didn’t want to get another fucking canker sore.

That whole toothpaste fiasco had me paranoid about what the f was in my toothpaste. I started to do more research and was shocked to find all the toxic ingredients that are in most major brand’s toothpaste.

Just to name a few:


There’s been a huge debate on fluoride. They say it helps keep teeth strong and cavity-free. They also say that ingesting too much of it can be extremely harmful and do things such as erode the mucosal lining of your stomach or damage to the kidneys. Less severe cases of fluoride ingestion include nausea, vomiting or diarrhea.

Sodium lauryl sulfate

I already gave you a little info on it earlier. SLS is added to a lot of personal care products as a detergent/cleanser. Other than potentially causing canker sores, it may damage eyes, irritate skin and cause sore throat/cough.

Diethanolamine (DEA)

This makes products foam. May cause hormone imbalances and allegedly “forms cancer-causing nitrates.”


The EPA classifies this ingredient as a pesticide that poses a risk to human health and the environment. Enough said.

Propylene glycol

There are a ton of negative claims about this stuff on the internet… The FDA claims this ingredient is safe, but they say a lot of terrible things are safe. One thing that’s for sure is that we dispense this all the time at work. What’s it for? To clean out your colon before a colonoscopy.


Not only are these bad for the environment, they’re bad for your mouth! They can get stuck in your gums and cause periodontal disease. What happened to me? Cut the hell out of my gums. Ouch!



Soooo, what now? For starters, just look at the ingredients in your toothpaste. What made the list? What’s important to you? Don’t just take my word for it, go do your own research and see how you feel about it.

Want my recommendations? Keep reading!

So far, I’ve tried two toothpastes without those nasty ingredients.

  1. Dr. Bronner’s
  2.  Jason’s Powersmile

Here are my thoughts:

Dr. Bronner’s Magic Soaps Cinnamon Toothpaste

This toothpaste is formulated without any toxic ingredients or any of the foaming agents that most toothpastes have.

The texture of this took some getting used to, but I got used to it eventually. The biggest downfall of this toothpaste (for me at least) is I could not get over the taste. I don’t know if all cinnamon toothpaste taste like that, but I found it absolutely awful. But maybe that’s because it reminds me of the morning after I had WAY too much Fireball. My face got to know my toilet really well if ya know what I mean. Honestly, I couldn’t get over how terrible the taste was. After using it for a few weeks, I just couldn’t take it anymore and I headed to Whole Foods to pick up the peppermint one. Unfortunately, the only flavor left was cinnamon, UGH! I wasn’t about to go another day using that toothpaste, so I searched for another.


That’s when I found Jason’s Powersmile Enzyme Brightening Toothpaste. I double checked the ingredients and it also is made without any of the nasty toxins listed above. I’ve had pretty good luck with other Jason products, so I figured I’d give it a try. (I will warn you that a lot of the Jason brand toothpastes had carrageenan in it. Although it’s been deemed harmless if ingested, I would prefer to stay away from it.) This particular one I bought did not have carrageenan in it.

I was pleased when I tried this toothpaste. I didn’t realize how much I would miss the minty freshness of a toothpaste until I suffered without it for two weeks.

When I looked over the ingredients of the two again, I found that Dr. Bronner’s list of ingredients was cleaner than Jason’s, so the next time I need to get toothpaste, I’ll probably get the Peppermint Dr. Bronner’s.  Again, just do your own research and see how you feel about it 🙂

Anyway, I’m off to go on my afternoon walk with Nala. Bye loves!

    […] I would rather NOT have to deal with these issues if it can be avoided, so I’m just going to keep it safe and swap out these products. I started with toothpaste which you can read about here. […]
