Plastic in Your Toothpaste? Understanding Microbeads

A few years ago, a surprising ingredient turned up in some popular toothpastes: tiny plastic beads. If you’ve ever wondered whether there’s plastic in your toothpaste — or noticed little colored specks — here’s the story.

What Are Microbeads?

Microbeads are tiny spheres of plastic, usually polyethylene, that were added to some toothpastes and cosmetic scrubs. In toothpaste they served no cleaning purpose — they were essentially decorative, meant to add color or texture.

Why Did Dentists Raise Concerns?

Because the beads don’t dissolve, dental hygienists began noticing them getting trapped in the small groove between the gums and teeth (the sulcus). Anything that lodges there and lingers can potentially trap bacteria and contribute to gum irritation over time. That’s enough reason to prefer toothpaste without them.

Are Microbeads Still in Toothpaste?

Mostly no. In the United States, the Microbead-Free Waters Act of 2015 banned plastic microbeads in rinse-off products, and major manufacturers phased them out. So most toothpaste on the shelf today is microbead-free — but it’s still worth a quick label check, especially with novelty or imported products.

How to Check Your Toothpaste

• Scan the ingredient list for polyethylene — that’s the plastic used in microbeads.
• Look for the ADA Seal of Acceptance, which flags products reviewed for safety and effectiveness.
• When in doubt, ask us at your next checkup and cleaning — we’re happy to recommend a good everyday toothpaste.
