What About Fluoride in Natural Toothpaste?
Fluoride is supposed to prevent tooth decay and cavities and help us have strong bones. But for decades, there was debate about whether fluoride is healthy and effective as an additive to drinking water and toothpaste.
I have long been against fluoride in drinking water. The Harvard School of Public Health reported that fluoride “adversely affect[s] cognitive development in children,” causing as much as a 7-point lower IQ. There is also persistent concern that fluoride can cause reproductive damage in high enough doses. Most recently, a federal court in California passed a ruling against the EPA, highlighting concerns about fluoride levels in drinking water.
If you’re worried that skipping fluoride means inviting a mouth of rotten teeth, there is evidence that vitamin D may help prevent cavities.
For these and other reasons, I recommend filtering fluoride out of drinking water–but if you have a cavity-prone child like I do, you might decide to use a natural toothpaste with fluoride.
Is Hydroxyapatite a Safe Alternative to Fluoride?
Hydroxyapatite, a naturally occurring mineral and the main component of tooth enamel, has gained recognition for its role in oral care products, including toothpaste. As an ingredient in toothpaste, hydroxyapatite has shown promise in remineralizing tooth enamel. Its ability to form a protective layer on the tooth surface helps repair microscopic enamel damage, contributing to improved overall oral health.
What (Else) Is Wrong with Natural Toothpaste?
For most people, I recommend choosing fluoride-free toothpaste. And yet toothpaste has to be more than fluoride-free in order to be safe.
Unfortunately, many “natural” toothpaste contain concerning ingredients similar to what’s found in conventional toothpastes, such as:
- Surfactants, usually coconut-derived substitutes for sodium lauryl sulfate (SLS), are popular ingredients in many “SLS-free” toothpastes. I’m concerned about some of these SLS alternatives in natural toothpaste because of the delicate and absorbent lining of the mouth. Examples of these kinds of surfactants are sodium coco-sulfate, sodium cocoyl glutamate, potassium cocoate, sodium lauroyl sarcosinate, and sodium methyl cocoyl taurate. It’s confusing, though, because when you look at each of these SLS substitutes one by one, some really do appear to be benign. For instance, sodium cocoyl glutamate and potassium cocoate each gets only a 1 from EWG, and they seem like a great substitute for SLS/SLES. Sodium lauroyl sarcosinate, on the other hand, gets as high as a 5 from EWG, so I recommend avoiding toothpastes that contain it. It may, however, be okay as a foaming agent in products that you do not put in your mouth–such as shampoo.
- Preservatives will show up in paraben-free toothpastes, and they still worry me. Sodium benzoate is suspected to cause damage to mitochondrial DNA, and is a persistently controversial ingredient. More research (especially long-term studies) is needed, but for now, this ingredient knocks brands out of our Best Stuff category, though they may still be Good Stuff. Potassium sorbate and sorbic acid have raised concerns due to mild allergic reactions in some users, but you will find these in brands we call Best Stuff.
- Carrageenan, derived from seaweed, is a common thickening agent in toothpaste. Animal studies suggest that it leads to intestinal inflammation and colon tumors. It’s probably fine in toothpaste for adults, but I’d avoid it in products used by swallowing-prone kids.
Natural Toothpaste Ingredients I'm NOT Worried About
There are several controversial ingredients that I’m not so worried about in natural toothpastes. These include:
- Glycerin. There’s a small but heated debate about whether glycerin, a very common ingredient in both conventional and natural toothpastes, is healthy for teeth. Some people claim that glycerin in toothpaste coats the teeth, blocking their ability to re-mineralize (or repair themselves with minerals from our saliva). It’s true that re-mineralization is crucial to the health of our teeth. It’s not clear, however, that glycerin-based toothpastes seriously interfere with this process. Honestly, I’m on the fence about this, so I’m giving the Okay Stuff label to otherwise safe toothpastes that are glycerin-based. (See Good Stuff for glycerin-free toothpastes).
- Clays are a potentially problematic ingredient in natural toothpaste because they can contain trace amounts of lead. After lots of research and digging into the independent testing of the bentonite clay used in Earthpaste, I’m convinced that it’s safe. The amount of lead in clay is much less than the naturally occurring amounts found in food like spinach or sweet potatoes. Also, the lead in clay doesn’t seem to be bio-available (meaning your body won’t absorb it even when it is present). Even better, there is compelling evidence that bentonite clay might actually RID the body of lead. You should always do your own research, but this is where ours has lead me, and I feel confident calling Earthpaste Good Stuff.
- Sugar alcohols like xylitol, sorbitol and erythritol are used in toothpastes for sweetness and anti-cavity benefits. When consumed in high enough amounts (usually as sugar replacements in food and beverages), they can cause digestive upset in some people. As a result, many parents ask me for recommendations of xylitol free toothpaste. Ultimately, I think this is more or less unnecessary. I don’t think they’re harmful in the small amounts found in toothpaste, and I like that xylitol and erythritol have anti-cavity benefits. The bottom line here is that there’s no need to go out of your way to choose a non toxic kids toothpaste without xylitol or sorbitol. (If you’re concerned about sugar alcohols, Earthpaste’s peppermint flavor is xylitol free, as are Tooth Soap’s products.)
- Essential oils are used in some natural toothpastes in place of artificial or natural flavors, and sometimes for added anti-cavity/pro-mouth benefits. Some people don’t like the idea of using essential oils in ingestible products, and some people have sensitivities to specific oils. I think that high-quality essential oils like the ones in the Good Stuff are safe in the amounts found in toothpaste, but if you want to avoid them, check out Poofy Organic’s toddler tooth gel, Jack n’ Jill’s toothpastes, and some of the Tooth Soap products (all Best or Good Stuff). Limonene, in particular, is found in various cosmetics, many of which are natural and organic. EWG considers limonene a definite skin and respiratory irritant, with potential carcinogenic properties. But there are different forms of limonene, and some research suggests that it has antioxidant and anti-cancer properties. Confusing? Yes. Deadly in toothpaste? Probably not, especially if you’re not guzzling it by the tube.
What Is the Best Non Toxic Baby Toothpaste?
Many kids’ toothpastes are officially for ages two and up. So what about younger toddlers and babies?
Teaching little ones to brush and getting them used to the tickling sensation of bristles is definitely important, but all you really need to use is water plus a soft-bristled brush or silicone toothbrush beginning with their earliest teeth.
You can hold off on toothpaste until they’re toddlers, or later. (Toothpaste isn’t actually essential to oral health—the brushing action of the toothbrush is. Flossing and a healthy diet are crucial, too, of course.)
If you feel compelled to use more than water (and/or kid’s your doc or dentist says you need to), try some of the Best or Good Stuff from this guide.

How do you feel about Dr Brite (adult and children). We just switched to using their products. I also use their mouth spray for my kids. I have been very happy with their customer service as I’ve asked them a lot about their ingredients (eg is their aloe pre-preserved, etc), and generally seem like a pretty great company all around!

I like Himalaya. I work in the industry (not for them) and as far as ingredients and taste, it’s my favorite. Second would be Weleda.

Thanks for the great guides. Have you looked into safe toothbrushes? I am currently using a silicone finger brush for my son and this brush for myself which has “vegetable oil based” bristles https://www.amazon.com/Bamboo-Toothbrush-Adult-Size-Pack/dp/B009O3BCT2/ref=sr_1_1_a_it?ie=UTF8&qid=1486050885&sr=8-1&keywords=brush with bamboo toothbrush. There seem to be many “BPA free Nylon” toothbrushes out there, but seems suspect. The only non-plastic option I have found seems to be very expensive and hard to find pig hair bristle brushes. Would love to know your recommendations.

How do you feel like toms childrens anticavity fluoride toothpaste?

Hello,
There is clay in earthpaste, and poofy organics toothpaste. I’ve been doing some of my own research and see that poofy organics uses a different brand of clay,living clay, and earthpaste uses Redmond clay. I noticed you said you’re comfortable with the clay used in earthpaste,redmond clay. Are you comfortable with the brand of clay used in poofy organics toothpaste, living clay? I know it’s okay stuff based on the glycerin, but I just wanted to know if Living Clay met your standards for clay! Thank you for your time!Maia James

Hi! Dr. Brite is Good Stuff (although insanely expensive on Amazon: http://amzn.to/2jPivGM).
Maia James
Hi there-I don’t know where else to purchase Toothsoap. If you want a toothpaste without any sugar, you can try the spearmint flavor of EarthPaste.
Natalie
Could you give some suggestions for mouth wash to use?
Jean
i just found your article and i can’t thank you enough. I have oral thrush for over 2 years which is a fungus in the mouth that feeds on sugar. i have been using regular toothpaste at bedtime and i wake up after 3 hours and have to clean my tongue. Want to try Redmond Spearmint and Toothsoap in whip form. Unfortunately many of the reviews on Amazon spoke of stale or close to expiration date products in regards to Toothsoap nd Vitacost does not carry the Toothsoap in the whip form, which i read most people prefer. Iherb website said Toothsoap is discontinued. I’m not sure but no one else carries the whip outside of Amazon-
I went to the company website and they are moving to West coast and website won’t be running until Feb. 1, 2017.
Do you know of any other places that I could try to get the Toothsoap whip or have you heard it was discontinued? I wonder if that’s why there were so many complaints on Amazon about expiration dates.
Please let me know of any new products that are sugar derivative free. Thank you so much for your expertise and help.
Maia James
I know the name but haven’t researched deeply enough to give you my opinion. Will add to our list for a future investigation!
Maia James
Meh, not so great. Cocamidopropyl betaine and a bunch of other synthetics.
Myra
Have you heard of a brand called Dental Herb company? I’ve used their products for many years but was curious to see if you had any experience with their products.

Sadly, I don’t know of a brand that has no other Bad Stuff but contains fluoride. Tom’s has SLS and carrageenan, but otherwise not horrible so I would go with one of those (we’ve used this: http://amzn.to/2bWzW3V).
Betty Jane Mackay
I am curious about this as well. I am looking for the safest toothpaste that contains fluoride.
Maia James
I would recommend any of the fluoride-fee options in this guide. My top pick and what we use is: https://gimmethegoodstuff.com/store/redmond-earthpaste-natural-toothpaste/
Maia James
I don’t love this one(mostly because of Cocamidopropyl betaine)
Maia James
We actually haven’t looked into that yet, but I will do some investigating!
Maia James
I haven’t seen and can’t find a list of ingredients for this, so I am sorry that I can’t weigh in.

Any suggestions on good toothpaste safe for pregnancy?
Lauren
I was doing some research, and came across The Natural Dentist. They have a Fluoride Free toothpaste with the ingredients listed here: http://www.bleedinggums.com/toothpastes/fluoride-free-toothpaste/fluoride-free-ingredients/. Are you familiar with this brand? Would love to know your thoughts. Thanks!
Jill
I have sensitive tears is there a brand you recommend for help with sensitive teeth?
Tabatha Tremble
What about tooth polish from melaleuca.com?
Maia James
Oh my goodness, so sorry to hear this! Because your symptoms are so severe, I would have a physician look over any toothpaste before using. I would also probably try going toothpaste-free for a while and see if your suspicions are correct and that clears up the problem.
Maia James
I don’t know that brand, but will add to our list to investigate!
linda nash
which toothpaste would you use if you are allergic to quaternium 15 and Isothiazolinone. My tongue swells and has sores around the edges. I have had every test and even a biopsy. This has been going on now for almost 2 years. I’m thinking it may be the toothpaste.
Shelley
Any thoughts on Himilaya Botanique Neem and Pomegranate fluoride free toothpaste?
Thanks so much!Sunshine1029
Ok great! Thank you! :)
Maia James
Looks fine to me, although EWG expresses concern over clove bud oil (you can look it up).
Maia James
I think so, yes. It does contain glycerin, which some people don’t like. But I still use it if I run out of Earth Paste:).

In your awesome detox ebook you wrote Jason’ Naturals sea fresh toothpaste was good stuff, but I don’t see it on here.. is it still good stuff??
Maia James
Any of the brands listed above are safe for adults.
Janis
Wonderful website. Thank you. What would you recommend as a safe affordable adult toothpaste. I ask because not everyone is able to order toothpaste from Amazon on an ongoing basis.
Maia James
It’s okay but it does contain glycerin.
Michelle
What about weleda?
Maia James
You should ask your dentist or pediatrician about how much coconut oil is safe, but I will tell you to definitely opt for unrefined coconut oil, as the refined variety is deodorized and bleached. And while there is a distinction between virgin and extra virgin olive oil, when it comes to coconut oil, these terms mean the same thing. Of course, I would recommend option for an organic coconut oil.
Danni
Hello,
Thank you for this incredible site. I’m in the process of replacing all the bad stuff. So scary.
Question regarding coconut oil. I was using babyganics to brush my one year old teeth. How much coconut oil is ok to use on him?
Do you recommend a certain brand of coconut oil?
Thank you!
Maia James
We did address the lead issue. (Bottom of the page here: https://gimmethegoodstuff.com/store/redmond-earthpaste-natural-toothpaste/
). This is what we said: *A note about lead: When we first were looking into clay toothpastes, we were really worried about the possibility of trace amounts of lead, especially since our kids are brushing with this. After lots of research and digging into the independent testing of the clay used in Earthpaste, we are convinced that it’s safe, mostly because the amount of lead in clay is much less than the naturally occurring amounts found in food like spinach or sweet potatoes, but also because the lead in clay doesn’t seem to bio-available (meaning your body won’t absorb it even when present). Even better, there is compelling evidence that bentonite clay might actually RID the body of lead. You should always do your own research, but this is where ours has led us, and we feel fine with our kids using–and likely swallowing!–Earthpaste twice a day.

Apologies, for above. The product in question is Earthpaste. Thanks.
