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.

On the updated guide, the KMF toothpaste is your recommendation for fluoridated toothpaste but it also appears to be listed under your Sneaky Stuff. Is this the same product or a different version!
Jen
Do you know anything about The Natural Dentist toothpaste with Flouride?
Daniel McMahon
As parents, it is really important to know the ingredients of the product that your kids use to ensure that the ingredients used can’t harm them. It is applicable not just for the toothpaste but all the products that they use often.
Suzanne Weaver-Goss
We haven’t researched Uncle Harry’s toothpaste but I just looked at it and at first glance it looks like Good Stuff!
Griselda
I am so grateful for all your guides! I find myself visiting your site first when looking into trying new healthy products. Thank you, all your information and time is highly appreciated. One question, what do you think of Uncle Harry’s Toothpaste?
Myriam
Hello,
I am wondering what are your thoughts about Silca Herbal flouride free toothpaste. I have been using it for over a year now but I am now wondering about the silica and hydrated silica included, not to mention the SLS etc.
Thanks
Joy Butler
Hi Maia, I’d like to thank you for your explanation about getting a fluoride-free toothpaste for my kids. I had no idea that it can cause reproductive damage with its high doses. Once we do our weekly grocery, I will look for a fluoride-free product. More power!
Maia James
Hi Howard, The Earthpaste spearmint does not have Xylitol because it is unsweetened. Hope you buy from us!!!
Raymond Hague
Thank you for sharing to us some of the tips on choosing the right toothpaste for our kids.
Howard Sample
You mentioned that Earthpaste Spearmint does not have xylitol, but the detail information on Amazon says xylitol is added ingredient. Which is correct, please? I cannot have xylitol.
Katherine Pirzadeh
Have you ever heard of radius brand organic coconut oil toothpaste? I just got some at whole foods and it looks like it might be OK?
Maia James
I’m fine with potassium sorbate as a (food-grade) preservative.
Maia James
Hi! No, the amount a toddler might smaller is definitely not a large quantity. (You should only be using a pea-sized amount of toothpaste, no matter the brand, for a child that age.)
Jennifer Schaperow
Thank you for this list. Is Xylitol safe for toddlers considering that they swallow toothpaste? I looked online and there is a lot of negative about it in large quantities. If it’s the first ingredient in toothpaste does that mean it’s in a large quantity? I’m considering using Jack And Jill toothpaste for my 2 year old. Thank you!
Madelyn
Hi there. Jack n Jill toothpaste have reformulated and added “potassium sorbate (naturally derived)” as their last ingredient. What are your thoughts on this?
Annmarie Zuluaga Yafrate
Why do you pick Kiss My Face Berry Smart Obsessively Kids Toothpaste over Tom’s of Maine for Flouride toothpaste? I’ve been using a rice sized spec of Tom’s of Maine with my LO (who is now 2.5 years old) for a while now but I’m starting to get concerned that many others use flouride free toothpaste. My pediatric dentist of course recommends the flouride toothpaste (twice a day), our pediatrician once a day. What to do what to do?
lee
I’m curious about this one too!
Vanessa
Sorry I should have added that this is green beaver toothpaste from r others who may be interested – but only their frosty mint flavour as I thought some of the others had more questionable ingredients.
Thanks!
Vanessa
Sound ok for toothpaste?
Calcium carbonate, sorbitol, aqua, glycerin, sodium bicarbonate, silica, xylitol, mentha piperita (peppermint) oil, citrus medica limonum (lemon) extract, calcium ascorbate, melaleuca alternifolia (tea tree) leaf oil, menthol, sclerotium gum, coco glucoside, xanthan gumThank you!

Oh found your comments about earth paste with lead. Still concerning to me so I guess I am back to looking for a more comfortable option.
Em
Redmond Earthpaste – On the toothpaste tube, it says Warning as it contains LEAD and may not be safe for children and pregnant women. How can it claim to be natural and safe? Got me worried there… Any thoughts?
Thank you!Karen
Would you still ok using Earthpaste while pregnant? Are you aware of anyone who has checked lead levels before and after use?
I’m interested in Nelson Naturals toothpastes. Ingredients: Calcium Carbonate, Sodium Bicarbonate, Colloidal Silver, Sea Salt, Xylitol, Castile Soap, Trace Mineral Concentrate, Essential Oil (Flavourings). A little iffy about the Colloidal Silver and exactly what the trace minerals are.Emily
Hello! Thank you for all of the great research! I have been using Jack n Jill toothpaste for my 20 month old, but saw that Hello Organic Apple tooth paste have been doing a lot better in reviews on Amazon. The ingredients are as follows: Vegetable Glycerin (Soothes and Moisturizes), Sorbitol (Humectant), Purified Water, Aloe Vera Gel (Soothes and Moisturizes), Hydrated Silica (Thickener), Xylitol (Sweetener), Erythritol (Sweetener), Xanthan Gum (Thickener), Flavor* (Yum), Calcium Glycerophosphate (Mineral), Potassium Sorbate (Maintains Stability), and Stevia Rebaudiana Leaf Extract (Sweetener). *Certified Organic
What do you think! The cost is 1/2 of Jack n Jills so thought if this one seems as good as Jack n Jills, I should go with this one :)JC Farmer
CA Prop 65 warning label (LEAD traces) does more to scare people than it does to inform people. This toothpaste has bentonite clay in it, which calls for the Prop 65 warning. long story short: carrots, potatoes, and turnips (root vegetables) are just as likely to contain higher amounts of lead than this product, along with many other products that carry the Prop 65 warning label.
Ivy
I saw on the earthpaste packaging, it said California Resident Proposition 65 warning. What is it about and should we be worrying about it? It said "This product contains a chemical known to the state of California to cause birth defects or other reproductive harm. This product may not be appropriate for consumption by children or pregnant women.
Lauren Young
Looking at trying to find something with fluoride to supplement a good toothpaste and came across the Natural Dentist Flouride Rinse. Is this a good addition for someone looking for Flouride but none of the other bad stuff?
Purified water, vegetable glycerin, aloe Vera gel, sodium phosphate monobasic, xylitol, natural flavors, polysofbate 80, citric acid, grapefruit seed extract, menthol.Mandy
Hi, I know this is about a year after most of the comments, so fingers crossed that you see this! But my 18 month old son has sensitive skin and I was told to get a non flavored toothpaste for him. Do you know of any toothpastes that are non flavored and don’t have any of the bad ingredients in them?
jessie reece
I’ve read reviews that say Earthoaste turns your teeth a dullish color (from the clay base); that their teeth take on the color of the earthpaste. Have you had this issue?
Aimee Rivello
Hi Maia,
Thank you as always for all of your great info!! I was wondering about Trader Joe’s floride free toothpaste?? I’ve been using it for years for me and my kids. My hubby refuses to change his toothpaste!! Hoping I get good news!! Thanks so much!!
Darshana Maya Greenfield
Personally I gave up using ANY toothpaste years ago, when my hygienist was worrying I was wearing the dentin off my teeth, and my dentist pointed out that toothpastes are abrasive – he said to just use the brush!
I was thrilled, and so enjoy not having any tastes in my mouth after I brush – which I can now do at my desk, in my car, wherever I am, as I just rinse and swallow pure filtered water after! I also get rave reports at my checkups – no issues, and I don’t even floss – though I do use tiny brushes or tiny toothpicks to clean between my teeth, every day or so. Glad you mentioned, near the end, that toothpaste is not essential – it is the brushing that is important! Hubby is not so happy with no toothpaste, so I found this one to substitute for the toxic one he used to use: https://www.vitacost.com/coral-llc-coral-white-toothpaste-mint I was particularly concerned with avoiding glycerin, as you mentioned. He’s pretty happy with it. And it leaves his breath less toxic than when he used Listerine or Colgate eek!Sara A Goegeline
I have dry mouth. I would love to find a toothpast and mouthwash that accommodate my problem and are safe-ish but, most importantly, cruelty-free. I’m an adult past child-bearing years, so I’m not as worried about certain contaminants as some of you are.
I also have an interest in ayurvedic dental hygiene products.
Denise
I read this article about toothpaste. It said that Earthpaste has lead in it.
Emily
What do you think about Uncle Harry’s toothpaste? This is the ingredient list:
Bentonite clay, calcium carbonate, Purified, deionized, microfiltered water and ten parts per million of silver mineral (99.000% pure), sea salt, ionic minerals, mustard seed, essential oils of peppermint, eucalyptus, clove, wintergreen, and oregano.Hasan
What are your opinions on the toothpastes were currently using?
My brother uses this one: https://www.hello-products.com/product/kids-fluoride-free-toothpaste-natural-watermelon/ (natural watermelon fluoride free toothpaste).For me it’s this one http://www.naturesanswer.com/index.php?main_page=product_info&products_id=2748 (PerioBrite Natural Toothpaste Coolmint).
Kmie
What about doterra on guard toothpaste ?
Stacia
Sorry- that posted too quick! What are your thoughts on Radius organic coconut oil toothpaste? Just came across it at Wegmans and wanted your opinion before I buy.
Melissa
I’d love to know the answer to this, as well.
Stacia
Hi, what are your thoughts on Radiis organic coconut oil toothpaste? Just came across it at Wegmans and wanted your opinion before I buy.
Court
Hi Maia – any thoughts on the below opposing argument on lead/clay?
http://tamararubin.com/2017/02/earthpaste/#navigationEstefany
I believe HELLO has two SLS free toothpastes; the kids watermelon and the adult sensitivity. I would also like to know you’re opinion on this toothpaste brand, as I’m in transition to cruelty free toothpaste and of course not filled with bad stuff. My family is so stuck on there old usual drug store brands, and I’ve heard good “tasting” reviews, as that has been a huge problem in trying to get my family to switch. I hope to hear from you!
Karen
Found my answer further up in the feed. Thanks :)
Karen
I planned to order Earthpaste. However, the website I was using had a customer warning as per California Residents Prop 65; advised it contains trace amounts of naturally occurring lead. Are you still using this product? Is it still recommended?
Sara
Jack N Jill recently changed their formation to add potassium sorbate and citric acid. What’s your take on these ingredients?
Amber
Hello! Have you looked at Young Living KidScents Slique Tooth Paste? I’m trying to decide if this is a sneaky product or not. It does contain Glycerin. My daughter really likes it, and I would like to stick with it, if it turns out to be an okay product. Any insight would be appreciated. In the meantime, I’m going to try out Earth Paste for myself. Thank you for posting.
Rachel
Jack n Jill has grabbed my attention. I was using dr. Brown tooth wipes and switched to j&j. What are your thoughts on their toothpaste? Thank you for all of your hard work and advice!
Maia James
Sniglar is a great option! you can get it completely unfinished:)
Maia James
We actually have a tube of this now because my son loves it, but I’m not a huge fan—it’s got SLS, for one.
taylor
What are your opinions on Hello Toothpaste?
Virginia
Oh and a section on nursery playroom items like a toddler kids table please would be great. Or just an opinion or feedback with your personal choice would be stellar. Thank you so much!
Virginia
Hi ladies, thank you so much for all of he research you have done and advice you have given. I’m looking for a non toxic crib and wish you could give me options that make your list of good stuff and the bad stuff. Currently thinking about the IKEA sniglar crib but have to check with them if their mattress board is from solid wood or plywood. Please let me know if any cribs that you think are the safest and non toxic but don’t cost more than $ 2-300.
Thank you!!!!
