Are Your Oral Care Products Full of Microplastics?

You brush your teeth twice a day, every day. That adds up to roughly 700 brushing sessions a year, and with each one, your conventional oral care products are contributing to one of the most pressing environmental issues of our time: microplastics.
The oral care industry generates an enormous amount of plastic waste. Toothpaste tubes, plastic toothbrushes, mouthwash bottles, floss containers. Most of it ends up in landfills or worse. And some of it, in the form of microplastics, ends up somewhere far more concerning: inside us.
What Are Microplastics?
Microplastics are plastic fragments smaller than 5 millimeters. They come from two main sources:
- Primary microplastics are products intentionally designed to contain small plastic particles, like microbeads in personal care products
- Secondary microplastics are larger plastic items that break down over time into smaller and smaller fragments through sun exposure, abrasion, and weathering
Microplastics are now found virtually everywhere:
- In oceans and waterways
- In soil used to grow produce
- In tap water and drinking water
- In human blood
In a landmark study, 17 out of 22 participants had detectable levels of microplastics in their bloodstream. What gets into the environment eventually gets into us.
How Oral Care Products Contribute to Microplastics
Most people think about plastic straws or water bottles when they think about microplastics pollution. Oral care rarely comes up, but it should. Here is where your bathroom routine is contributing to the problem:
Toothpaste tubes
Nearly every conventional toothpaste tube is made from a laminate of plastic and aluminum that cannot be separated, which means they cannot be recycled through standard programs. Every tube goes straight to landfill, where it breaks down over centuries and sheds microplastics into surrounding soil and water.
Microbeads in toothpaste
Some conventional toothpastes contain microbeads, tiny plastic spheres made from synthetic polymers like polyethylene and polypropylene, used as mild abrasives to scrub teeth. These microplastics rinse directly down your drain and into water treatment systems that are not designed to filter particles that small. From there, they flow into waterways and oceans.
The US banned microbeads in rinse-off cosmetic products in 2015 through the Microbead-Free Waters Act. However, the regulation does not cover all categories, and rules vary internationally. Always check your ingredient list for polyethylene or polypropylene. If you see them, your toothpaste contains microplastics.
Plastic toothbrushes
The average person goes through around 300 toothbrushes in their lifetime. Nearly all conventional toothbrushes are made from non-recyclable plastic. Those 300 toothbrushes will outlive you by centuries, slowly breaking down into microplastics that work their way into soil and water.
Mouthwash bottles and floss packaging
Mouthwash comes in large plastic bottles that are replaced regularly. Floss packaging is almost entirely plastic. These small items collectively add up to a significant amount of microplastics-generating waste per household each year.
Why Microplastics in Oral Care Are Especially Concerning
When microplastics enter water systems, they attract and concentrate harmful chemicals including endocrine disruptors, which are compounds that interfere with your body's hormonal system. PET plastic, used in many bottles, contains phthalates, a class of chemical with well-documented links to hormonal disruption.
For oral care specifically, the concern is direct exposure. You brush with these products twice a day, inside your mouth, which is one of the most absorbent tissues in your body. Repeated daily exposure to microplastics or plastic-derived chemicals, even in small amounts, is not something to take lightly.
How to Remove Microplastics From Your Oral Care Routine
The good news is that plastic-free oral care has come a long way. Here is how to swap out each product:
- Replace your toothpaste tube with toothpaste tablets. Huppy toothpaste tablets come in a recyclable metal tin with zero plastic packaging, no microbeads, no SLS, and no artificial additives. One tin holds a month's supply.
- Switch to plastic-free floss, available in compostable or glass packaging, replacing the plastic dispenser that otherwise heads straight to landfill.
- Use a bamboo toothbrush. Bamboo handles are genuinely biodegradable, significantly reducing the microplastics footprint of one of your most frequently replaced products.
- Choose mouthwash tablets over bottled mouthwash. This eliminates the large plastic bottle from your routine entirely.
Small swaps made consistently add up fast. Two people in a household switching to plastic-free oral care can eliminate hundreds of plastic items from their waste stream over the course of a single year.
Key Takeaways
Microplastics are tiny plastic fragments under 5mm found in human blood, drinking water, and oceans
Your oral care routine is one of the most overlooked sources of microplastic exposure
Toothpaste tubes, plastic toothbrushes, and mouthwash bottles all contribute to the microplastics problem
Some conventional toothpastes still contain microbeads — tiny plastic particles that rinse straight down your drain
Switching to plastic-free oral care is one of the simplest and most impactful daily swaps you can make
The Bottom Line
Microplastics in oral care products are a real and underappreciated problem. From toothpaste tubes that cannot be recycled, to microbeads that rinse directly into waterways, to plastic toothbrushes that outlast generations, your twice-daily routine has a microplastics footprint most people have never considered.
The oral care category is also one of the easiest places to make a meaningful change. Unlike replacing a car or renovating your home, switching your toothpaste takes about thirty seconds and costs roughly the same as what you are already spending.
If you are looking for a place to start reducing your microplastics footprint, your bathroom cabinet is an excellent place to begin.

Frequently Asked Questions
Do toothpastes still contain microplastics?
Some do. Check the ingredient list for polyethylene, polypropylene, or nylon. If you see those listed, the product contains microplastics. Huppy toothpaste tablets contain none of these ingredients.
Are toothpaste tubes recyclable?
Most conventional toothpaste tubes are not recyclable through standard programs because they are made from a laminate of plastic and aluminum that cannot be separated. Tube-free alternatives like toothpaste tablets eliminate the problem entirely.
How do microplastics get into the human body?
Microplastics enter the body through ingestion, inhalation, and absorption through mucosal tissue. Oral care products that contain plastic particles, or are packaged in plastic that degrades over time, are a direct route of daily exposure.
What is the Microbead-Free Waters Act?
It is US legislation passed in 2015 that prohibits the manufacture and sale of rinse-off cosmetic products containing intentionally added microplastics in the form of plastic microbeads. It was an important step forward, though it does not cover all product categories or international markets.
Are bamboo toothbrush bristles plastic-free?
Most bamboo toothbrushes still use nylon bristles, which are a form of plastic. The handle represents the majority of the product's weight and volume and is the most impactful part to replace. Some brands are developing plant-based bristle alternatives, though options are still limited.
Are toothpaste tablets as effective as regular toothpaste?
Yes. Quality toothpaste tablets contain the same active cleaning agents as conventional toothpaste in a concentrated solid form. The brushing action does the majority of the cleaning work, and tablets support it just as effectively.
