In Your Daily Habit
Your Plastic Replacement Heads Are Feeding You 2.3 Million Microplastics a Year
Plastic bristle heads shed 2.3 million microplastic particles a year, about 3,000 every brush. Under sonic vibration that speeds up, and your gums soak it straight into your bloodstream. (PMID:40680448)
With PRIMALS Horse Bristle Heads
- 🌿Zero Microplastic SheddingReal horse bristles on a bamboo head. No nylon to grind into your gums.
- 🔄Keep Your Handle, Drop The PlasticYou changed the head every few months anyway. Now every new one is natural.
Backed By Research
The Plastic In Your Mouth Is Ending Up In Your Heart and Brain
Those particles don't leave. They build up in your organs, and have been found in human arteries, brain tissue, and breast milk. A 2024 study linked microplastics in arteries to a 4.5x higher risk of heart attack, stroke, and death.
With PRIMALS Horse Bristle Heads
- 🚫No More MicroplasticsNo plastic bristles, so nothing sheds into your gums when you brush.
- ✅The Easiest Exposure To CutMost microplastic sources are hard to avoid. This one you can remove today.
Is a Mold Trap
Your Old Plastic Head Was Quietly Growing Mold and Bacteria
A plastic head sits wet in your bathroom for weeks, and mold and bacteria breed inside it where you can't see or clean. Then you put all of that back against your gums twice a day.
With PRIMALS Horse Bristle Heads
- 🔥Heat-Carbonized BambooThe bamboo base is heat-treated, so it doesn't grow mold like a plastic head.
- 💧Dries Clean, Stays AntimicrobialNatural bristle and bamboo shed moisture and resist bacteria between uses.
Gentle On Your Gums
Soft On Your Gums, So You Stop Brushing Away Your Gumline
Hard and stiff bristles scrape at fixed angles and are a leading cause of gum recession and enamel wear, and once your gumline recedes it doesn't grow back. Horse bristle is the softest natural bristle, so it flexes and cleans gently. Ideal for sensitive teeth and kids 6 and up.
With PRIMALS Horse Bristle Heads
- 🪶Softest Natural BristleThe gentlest option for sensitive gums, receding gumlines, and kids 6+.
- 🛡️Protects Your GumlineFlexes instead of scraping, so you clean without wearing gums and enamel down.

No. Horse bristle is the softest natural bristle, but it still cleans thoroughly. It's naturally tapered, so it flexes into the gumline and lifts plaque gently instead of scraping like stiff nylon. Want firmer? Swap in our boar bristle heads on the same handle.

Yes. A few bristles may shed at first as the bamboo adjusts to humidity. This is normal and usually stops within 1 to 2 weeks. Leave a 0.5 to 1mm gap between the head and handle, and stand it upright to dry.
