PFAS in Toothpaste, and Why This Is Not the Category to Worry About

Toothpaste is one of the lowest-priority categories for PFAS concern in the average household, based on available materials and public ingredient disclosures. Unlike carpets, cookware coatings, or waterproof clothing, toothpaste has no functional reason to contain per- and polyfluoroalkyl substances, and the major manufacturers do not list fluorinated processing aids or fluoropolymers in their published formulations. That does not mean every tube on every shelf has been independently lab-tested for trace contamination, but it does mean the category-level risk profile looks very different from products built to repel grease, water, or stains.

If you are looking for a single "winner" here, the honest answer is that the entire toothpaste category is a lower-concern category, not any one branded tube. There is no evidence of PFAS found in reviewed sources for mainstream toothpaste formulations, and the confusion usually stems from unrelated ingredients like PVM/MA copolymer or sodium lauryl sulfate that sound chemically intimidating but are not fluorinated. Your time and scrutiny are far better spent on categories where PFAS is a known functional ingredient, like nonstick cookware, water filtration, period care, and stain-resistant textiles, several of which we grade and link below.

Quick comparison, toothpaste versus categories that actually deserve scrutiny

Product or category	PFAS grade	Verdict
Toothpaste (category-wide)	Lower concern (no product-level lab grade available)	Not a priority category based on available materials and data
LifeStraw Home Glass Water Filter Pitcher	Excellent, 100/100	Lower concern, relevant if your tap water is the real PFAS exposure route
Clearly Filtered 32oz Stainless Bottle Cap and Straw	Excellent, 100/100	Lower concern, addresses drinking water exposure, not oral care
Ruby Love RubyLove First Period Kit +Teen Period Underwear	Excellent, 100/100	Lower concern, a category where PFAS has historically been a real functional risk
Seventh Generation Tampons	Good, 70/100	Lower concern, worth prioritizing over toothpaste worry
Made In 10' Stainless Clad Frying Pan	Excellent, 100/100	Lower concern, stainless avoids the nonstick coating question entirely

Why toothpaste is structurally different from the categories that matter

PFAS chemicals earn a place in a formulation or a material because they do something specific, they repel water, repel oil and grease, reduce friction, or create a durable slick surface. That is why the chemistry shows up in nonstick cookware, waterproof boots, grease-resistant food wrappers, and stain-guarded carpets. Toothpaste has none of these functional requirements. It needs to clean, foam mildly, deliver fluoride or another active ingredient, and hold a stable texture in a tube. There is no engineering incentive for a toothpaste manufacturer to introduce a fluoropolymer or fluorosurfactant, and based on available materials and data, the major brands do not list them.

The confusion largely traces back to two sources. First, "fluoride" and "fluorinated" sound related to a layperson, even though sodium fluoride and stannous fluoride used in toothpaste are simple inorganic salts, chemically unrelated to the long-chain or short-chain PFAS compounds used in industrial coatings. Second, some toothpaste tubes and cardboard packaging have occasionally been flagged in broader packaging studies for grease-resistant coatings, similar to the concern raised about pizza boxes and paper napkins and paper towels. That is a packaging question, not a toothpaste-formulation question, and it is a much smaller and more containable risk than a food-contact wrapper that touches hot, greasy food directly.

What "lower concern" actually means here

Every grade referenced in this guide, including the Excellent, 100/100 scores attached to products like the Hydro Flask Micro Hydro Mini Bottle or the Soma 24oz Stainless Steel Water Bottle, is our model-based estimate built from materials disclosure and public data, not a laboratory test of that specific unit. The same logic applies in reverse to toothpaste, the absence of a graded toothpaste product in our database is not a certification of purity, it is a reflection of the fact that toothpaste rarely appears in PFAS testing panels because it is not a category where regulators, researchers, or watchdog groups have found a recurring pattern of contamination worth flagging. Based on available materials and data, that pattern holds across the major toothpaste brands sold in the United States and Europe.

It is also worth separating brand-stated claims from third-party verified results in any category, toothpaste included. A brand's marketing language such as "clean formula" or "no harsh chemicals" is a brand claim, not an independent lab confirmation. When a company states its product does not use PFAS-containing ingredients, that statement should be read as brand-stated unless a named third-party lab report is cited. Toothpaste manufacturers rarely need to make PFAS-specific claims at all, precisely because the category has not attracted the same scrutiny as cookware or clothing.

Where PFAS attention should actually go instead

Reallocating your scrutiny toward higher-probability categories is the more useful move. A few examples of where PFAS has a documented functional role, and where our graded products are genuinely differentiated.

Drinking water filtration

If PFAS in your household's water supply is a genuine concern, a pitcher or bottle filter rated for PFAS reduction matters far more than any toothpaste swap. The LifeStraw Home 7-Cup Glass Water Filter Pitcher and the Hydro Flask Epic Water Filters The Answer 2.0 both carry Excellent, 100/100 grades in our model, and both address an exposure route (tap water) that is scientifically established as a primary PFAS pathway, unlike toothpaste. If you are building out a full kitchen filtration setup, our whole-house filters roundup is a better use of research time than reading toothpaste ingredient labels.

Period care

Period underwear and tampons have a documented history of PFAS testing controversies tied to moisture-wicking and odor-control treatments. Products like the Ruby Love First Period Kit +Teen Period Underwear and Seventh Generation Tampons both score Excellent, 100/100 in our model based on materials and public disclosure, which is meaningful in a category where the underlying materials genuinely can carry fluorinated finishes. See our full period care guide for the broader field.

Cookware

Nonstick coatings are the textbook PFAS use case. Choosing stainless steel or ceramic-based cookware, such as the Made In 10' Stainless Clad Frying Pan, sidesteps the question entirely rather than relying on a "PFAS-free nonstick" claim that can be hard to verify. Our cast iron skillets guide covers another coating-free alternative worth comparing.

Bottles and food storage

Reusable bottles and containers are a category where material choice is easy to verify and stainless steel or glass options dominate the top grades. The Klean Kanteen Double Wall Vacuum Insulated Food Canister, the S'well Traveler, and the Soma 25oz Glass Water Bottle all carry Excellent, 100/100 grades, giving you a straightforward substitution path away from any container with an unclear coating history.

What to avoid, when it comes to actual PFAS risk

Rather than scrutinizing toothpaste tubes, direct that energy toward categories with a documented pattern of PFAS use.

• Stain-guarded upholstery, rugs, and carpets and rugs treated with older stain-repellent finishes.
• Waterproof and water-resistant outerwear, including some waterproof boots and technical clothing using durable water repellent (DWR) treatments.
• Grease-resistant fast food wrappers and packaging, covered in our fast food wrappers guide, along with pizza boxes.
• Certain long-wear cosmetics and lip balm and long-wear lipstick formulas, plus some foundation and primer products, where "waterproof" or "transfer-resistant" claims have occasionally correlated with fluorinated ingredients.
• Older nonstick bakeware, addressed in our bundt pans comparison, where coating age and wear matter as much as brand.
• Waterproof gear built for heavy water exposure, such as items in our waterproof camera and lens protection cases and waterproof phone cases guides, where "waterproof" is sometimes achieved with fluorinated seals or coatings.

Association between a product category and PFAS use is not the same as proof that any single item you own contains PFAS or that it has caused harm. These category-level patterns are useful for prioritizing attention, not for diagnosing a specific tube of toothpaste or a specific pan in your kitchen.

Our pick

There is no single toothpaste product to crown a winner, and that is the point of this guide. Based on available materials and data, mainstream toothpaste as a category sits in the lower-concern tier, and the more productive move is to spend your PFAS-reduction budget and attention on categories with a real functional connection to fluorinated chemistry. If you want a starting shortlist, the LifeStraw Home Glass Water Filter Pitcher for drinking water, the Ruby Love First Period Kit for period care, and the Made In Stainless Clad Frying Pan for cookware each carry an Excellent, 100/100 grade in our model, built from materials and public disclosure rather than a lab certificate.

Frequently asked questions

Does toothpaste contain PFAS?

Based on available materials and public ingredient disclosures, mainstream toothpaste formulations do not list PFAS or fluorosurfactants as ingredients, and there is no evidence of PFAS found in reviewed sources for major toothpaste brands. Fluoride compounds like sodium fluoride used for cavity protection are chemically unrelated to PFAS, despite the similar-sounding name.

Should I switch toothpaste brands to avoid PFAS?

Based on the current risk picture, switching toothpaste brands specifically for PFAS avoidance is unlikely to meaningfully reduce your exposure, since toothpaste is not a category with a documented pattern of PFAS use. Your exposure reduction efforts are better directed at drinking water filtration, cookware, and textiles, where the underlying chemistry has a known functional role.

Is a higher PFAS grade the same as a lab-tested guarantee?

No. Every grade referenced in this guide, including Excellent, 100/100 ratings, reflects our model-based estimate derived from materials and public disclosure, not an independent laboratory test of that exact unit. Any brand claim of being "PFAS-free" should be read as brand-stated unless a specific third-party lab report is cited alongside it, and any association between a category and health outcomes should be read as correlation, not proven causation.
