Triclosan in Toothpaste: The Warning That Expired

Read almost any guide to clean oral care, ours included until today, and you’ll find triclosan on the list of things to avoid in toothpaste.

It’s a strange entry, because the ingredient has effectively left the category.

This one is worth walking through carefully, partly because the details are odder than you’d expect, and partly because it’s a good example of a health warning that outlived the problem it described.

What actually happened

Triclosan is an antibacterial. It was added to toothpaste for a real reason: it reduces plaque and gingivitis, and Colgate Total had FDA approval on the strength of that.

In 2016 the FDA banned triclosan and eighteen other antimicrobials from consumer antiseptic washes. The reasoning was that manufacturers hadn’t shown these ingredients did anything ordinary soap doesn’t, and that long-term exposure carried risks worth avoiding. The concerns centered on hormone disruption in animal studies and on contributing to antibiotic resistance.

Then comes the part everyone drops. The FDA explicitly did not ban it from toothpaste. It concluded that in this one application the benefit, evidenced gingivitis reduction, outweighed the risk. The 2016 rule covered soaps and body washes only.

So for a few years the accurate statement was: triclosan is banned from your hand soap, permitted in your toothpaste, and present in one major product.

Then Colgate reformulated. From January 2019, Colgate Total relaunched without triclosan, built around stannous fluoride instead and sold as Colgate Total SF. The company that had defended the ingredient hardest simply stopped using it.

Where that leaves you

For practical purposes, triclosan is not a live concern when buying mainstream toothpaste in the US. It was never in most natural brands, and the one big product that carried it dropped it years ago.

It is not banned in toothpaste, which is the nuance worth keeping. Nothing stops a manufacturer from using it, so the ingredient list remains the place to check, above all for older stock or products bought outside the US. It’s simply no longer the thing standing between you and a clean tube.

Which makes it a poor reason to switch brands today, and we’d rather say so than keep an easy villain on the list.

If you want the reasons to change toothpaste that still hold up, they’re the ones in our roundup of the best natural toothpaste: whether there’s a real remineralizing active in the tube, whether SLS is irritating your mouth, and whether you’re paying for a charcoal product with no active at all.

Why the warning stuck around

Because “banned chemical found in toothpaste” is a far better headline than “regulator makes narrow exemption after weighing evidence”, and because the 2016 ban was widely reported without the toothpaste carve-out attached.

Once a claim like that is loose, it self-replicates. Every clean-beauty listicle copies the previous one, and few go back to check whether the underlying fact moved. Ours did the same, which is why this piece exists.

The useful habit here isn’t specific to triclosan. When a guide warns you about an ingredient, it’s worth asking when the warning was written and whether anything has changed since. Reformulation is common, regulation moves, and a stale warning crowds out a live one. That’s the same discipline we apply to certifications that lapse quietly in our greenwashing guide.

Frequently asked questions

Is triclosan banned in toothpaste?

No. The FDA’s 2016 rule covered consumer antiseptic washes such as hand soap and body wash. Toothpaste was deliberately excluded because the agency judged the gingivitis benefit to outweigh the risk. It remains legal, it’s simply no longer used by the major brand that made it famous.

Does Colgate Total still contain triclosan?

Not since the January 2019 reformulation. The current product is built on stannous fluoride and was launched as Colgate Total SF. If you have an old tube at the back of a cupboard, check the ingredient list.

Was triclosan actually harmful in toothpaste?

The concerns that drove the soap ban were hormone disruption in animal studies and antimicrobial resistance, and they were about broad, repeated exposure across many products. The FDA’s own assessment for toothpaste concluded the benefit outweighed the risk in that specific use. Reasonable people disagreed about it, and the debate is now largely academic.

What should I check on a toothpaste label instead?

Whether there’s a remineralizing active at all, either fluoride or hydroxyapatite. That single question matters more than any ingredient you’re trying to avoid, because a tube with no active isn’t protecting your teeth no matter how clean the rest of the list looks.
