You are Ingesting 2.3 Million Microplastic Particles Every Year - Just From Your Toothbrush

A silent threat that builds up day after day - and you don’t even know it.

MAKE THE CLEAN SWITCH NOW

THE TOXIC TRUTH ABOUT PLASTIC TOOTHBRUSHES

1. Your Toothbrush Is Feeding You 2.3 Million Microplastic Particles Every Year

In 2023, a PubMed study (PMID: 38092338) found that up to 120 microplastic particles are released into your mouth every time you brush with a plastic toothbrush. That added up to over 88,000 plastic fragments per year. That was alarming enough.

Then in 2025, a new peer-reviewed study (PMID: 40680448) revealed the real number is 26x worse — your plastic toothbrush releases an average of 2.3 million microplastic particles per year. 63% of those particles are under 100 μm — small enough to absorb directly into your tissue.

This isn't a small issue. It's a massive problem hiding in plain sight.

Friction breaks down plastic bristles: Daily back-and-forth motion wears down the nylon bristles in your toothbrush, causing them to fray and fragment into microplastics.

Degrades into nano & microplastics: Heat and saliva from your mouth further weaken the material structure, breaking down nylon bristles into micro and nanoplastics.

It’s a daily dose of plastic: Twice a day. 365 days a year. Over 3,000 particles per session are becoming part of your everyday routine — without you even realizing it.

MICROPLASTICS DON’T JUST STAY IN YOUR MOUTH

2. They Get Inside Your Body Every Time You Brush

Those tiny plastic particles? They don’t just disappear. Your daily brushing routine is also giving plastic a direct route into your body.

Here’s how it happens:

Absorbed through your gums: Your gums are highly absorbent - like sponges. Microplastics pass straight through and enter your bloodstream directly.

Swallowed with your saliva: As you brush, these plastic fragments mix with your saliva and are unknowingly swallowed with every rinse.

Embedded in soft tissues: Your mouth isn’t just a passage - it’s an entry point. Microplastics linger and embed in the soft tissues of your gums and cheeks.

THE CHEMICALS HIDING IN YOUR TOOTHBRUSH

3. Microplastics Release Cancerous Toxins Into Your Body

Microplastics aren’t just tiny bits of plastic - they’re chemical carriers. Each particle leaches BPA, phthalates, and other endocrine-disrupting toxins directly into your body. And remember - plastic is made from crude oil. These aren’t harmless fragments. They’re toxic time bombs.

Here’s what they’re doing inside you:

Disrupt your hormones: BPA and phthalates are known endocrine disruptors - they throw off your body’s hormonal balance, affecting everything from metabolism to fertility.

Trigger gut imbalance: Swallowed microplastics damage your gut microbiome, leading to digestive issues, bloating, and poor nutrient absorption.

Cause chronic inflammation: Your immune system sees these particles as invaders - kicking off an inflammatory response that weakens your health over time.

Increase cancer risk: Studies have linked plastic-derived chemicals to multiple cancers, making this a long-term health threat you can’t afford to ignore.

Uses animal fibers to eliminate microplastic intake while brushing

I love the Boar Bristle & Bamboo Toothbrush because the bristles are composed entirely of animal fibers. That means they are made without plastic like many toothbrushes you would find at the store. Research in Environmental Pollution found that standard plastic toothbrushes can and often do shed microscopic particles or "microplastics." Over years of brushing, those microplastics can quickly accumulate, so I encourage patients to explore plastic-free alternatives like this one from PRIMALS. It's great that the boar bristles can be effective for cleaning the teeth and protecting the enamel as well. There is a lot that I like about this product, and I would happily recommend it as part of an oral care routine.

Encourages gentler brushing with soft and flexible bristles

I highly recommend the PRIMALS toothbrush to patients whose gums may be irritated by stiff nylon bristles. A review of research found that hard-bristle toothbrushes can cause more gum abrasions than softer options, suggesting that soft and extra-soft brushes tend to be safer choices for most people. I expect many patients may notice that the boar bristles on this toothbrush feel noticeably softer and more flexible than standard nylon. This can offer a gentler brushing experience for sensitive gums. I appreciate the boar bristles are woven directly into the head, avoiding the use of glue or adhesives that may become triggers of irritation. After reading the research, I feel good about this product as a comfortable, low-chemical option for everyday brushing.
