Here's your old plastic toothbrush...

... versus your new PRIMALS Horse Bristle & Bamboo toothbrush
You've got questions. We've got answers.
What's so bad about plastic toothbrushes?
Plastic toothbrushes are made with nylon bristles and of course a plastic handle. Both plastic and nylon are derived from petroleum and contain BPA, phthalates, PFAS and many other carcinogenic and hormone disrupting compounds. As you brush your teeth with these nylon bristles - microplastic fragments are broken off, absorbed, and swallowed. In result, you are unknowingly dosed with said toxic compounds daily. This is in addition to the fact that nylon bristles are much coarser than horse bristles and can cause enamel damage and a receding gum-line.
Not to mention, the massive environmental damage that plastic toothbrush production and waste impose. Every year, 1 billion plastic toothbrushes are disposed of in the US alone, leading to over 50 million pounds of plastic waste. Since plastic takes hundreds of years to decompose, this leads to irreversible damage to our ecosystems.

What's different about ours?
While other "bamboo toothbrushes" on the market claim to be clean or eco-friendly simply because they have a bamboo handle - that only solves half the problem since they still contain nylon bristles. Those nylon bristles are derived from petroleum and are harmful not only to the environment but to your systemic health due to their cancer causing and hormone disrupting properties.
In addition, one of the main problems with other bamboo toothbrushes is that they do not dry properly which leads to molding. However that is not an issue whatsoever with our PRIMALS Horse Bristle Toothbrushes. Since our toothbrush is designed to stand on its own, and is sealed on the bottom with a non-toxic paint - it dries quickly and efficiently so it lasts longer than any other toothbrush on the market.
What’s the difference between the Horse Bristle and Boar Bristle Toothbrushes?
Both are great 100% natural and toxin-free options, but they offer slightly different brushing experiences.
Our Boar Bristle Toothbrush is slightly firmer that still feel gentle but give you a deeper, more satisfying clean, great for your long day of eating and drinking. It’s ideal if you prefer a firmer bristle feel. Check it out here.
Our Horse Bristle Toothbrush is perfect for people who prefer softer bristles, especially for those with sensitive gums or enamel. The bristles are fine and flexible, almost like silk, making the absolute best option for keeping your teeth squeaky clean while being as gentle as possible.
As you can see, both are exceptional options - it is simply a matter of if you prefer softer or firmer bristles!
Does it work as well as an electric toothbrush?
Yes-and even better. One reason we created the PRIMALS Horse Bristle Toothbrush is because electric toothbrushes emit EMFs (electromagnetic fields) right next to your brain-daily. Studies show levels can reach 70–90 µT near the head, and long-term exposure has been linked to poor sleep, reduced focus, and neurological stress.
PRIMALS keeps it clean and primal-no electricity, no EMFs, no toxins. Just natural horse bristles and a bamboo handle that protect your health while keeping your teeth fresh the way nature intended.
Is the PRIMALS Horse Bristle Toothbrush safe for kids?
Absolutely. Recommended for children aged 6 and up, it’s one of the safest and softest toothbrush options available. Unlike plastic or electric toothbrushes that can expose kids to harsh chemicals and EMFs, the PRIMALS Horse Bristle Toothbrush is made with natural, non-toxic materials-zero plastics, zero EMFs.
Its soft bristles are gentle on sensitive gums, making it ideal for younger users who need a gentler touch. With PRIMALS, you’re giving your child a clean, plastic-free start to oral care-safe, gentle, and aligned with nature.
How long does it last?
Our PRIMALS Horse Bristle Toothbrush lasts longer than any other toothbrush on the market.
While plastic toothbrush bristles fray out over time, making them unsafe to use due to microplastic fragmentation which puts you at risk for the host of chemicals in nylon bristles - our PRIMALS Horse Bristle Toothbrushes do not have this issue as we use 100% natural horse hair bristles.
Not to mention, due to the free-standing design of our bamboo handles and the non-toxic paint seal on the bottom of our toothbrushes - our toothbrushes dry quickly & effectively after each use - making them last longer than any other bamboo toothbrush on the market.
Overall each of our PRIMALS Horse Bristle Toothbrushes can last you well over 3 months each - meaning each 4 pack can last you well over a year each.
Some tips to note!
Some extra tips to note:
- Since our toothbrushes are glue free, all of the horse bristles are woven into small holes in the brush head. So in your first few uses of the brush, a few bristles may naturally shed as your brush is acclimating to your local temperature and humidity since bamboo expands in humid air and can then contract when it gets dry. Do not buy if you are not fine with removing a few bristles from your mouth that may shed in your first few uses. However, if you can stay the sustainable, toxin-free course and keep brushing - your brush will find a balance within the first few uses and you can brush away as vigorously as you like!
- Use the free-standing handle to stand the toothbrush up after each use for optimal drying to maximize life span of each toothbrush
- To make the bristles even softer, simply run it under warm water before use
- If you notice the brush bristles are being flattened - you are likely brushing with too much force. Apply slightly less force and brush in circular motions for optimal teeth cleaning and brush usage

A Hidden Threat in Your Daily Habit
You're Ingesting 88,000 Microplastics - Just from Brushing.
A PubMed-backed study revealed that plastic toothbrushes release up to 120 microplastic particles per brushing session - more than any other oral care product. That’s over 88,000 microplastic fragments ingested every year, just from brushing your teeth. These particles are invisible but highly toxic, entering your body silently, every day.

You’re Not Just Brushing - You’re Absorbing Plastic
Plastic Bristles Break Down and Invade Your Body.
Every brush stroke turns your toothbrush into a microplastic delivery system. As plastic bristles degrade, they release tiny shards laced with toxins like BPA and phthalates- harmful chemicals linked to hormone disruption and chronic disease. These fragments are absorbed, and even enter your bloodstream, circulating through vital organs. Brushing your teeth shouldn’t mean exposing your body to synthetic toxins.

A Growing Health Concern - Backed by Research
Microplastics Fuel Inflammation and Systemic Harm.
Once inside, microplastics don’t just pass through. They accumulate, triggering oxidative stress, weakening your immune system, and disrupting your gut and hormone balance. Research links long-term exposure to chronic inflammation, fatigue, and even infertility- all from something as simple as brushing your teeth with plastic.

I’m pleasantly surprised. It glides over teeth and gums without any discomfort, but my mouth feels clean and fresh after every use. I love that it’s gentle and 100% natural.
After some gum recession, I was told to use softer brushes. This horse bristle option has been perfect. It cleans well but is gentle enough that I can brush twice a day without worry.
This toothbrush is now my go-to for my morning routine. It’s soft on the gums and gives me a clean, refreshed feel without any harshness. It’s the only one I’ve found that doesn’t cause bleeding when brushing.
I tried out your toothbrush for the first time yesterday. My teeth never felt cleaner I was amazed how well bristles cleaned my teeth. I will never use those plastic toothbrushes ever again. I bought everyone in my house one. Hopefully in the future you can make ones that fit electric toothbrushes. Thanks Mike LaFontaine
Bought this as part of a plastic-free routine, but I was surprised by how well it works. It’s not just gentle, it actually cleans. Feels good knowing it won’t end up in a landfill.
