The Years
of Questions
For years, the anxiety was just background noise. A low hum that became so familiar it started to feel like personality rather than symptom. Gut problems followed — bloating, inflammation, the kind of chronic discomfort that doctors shrug at and call stress. Every blood panel came back clean. Every scan showed nothing. The answers weren't where conventional medicine was looking.
Our founder had spent years building toward a cleaner life — organic food, filtered water, clean-label skincare. And still, something wasn't right. The question that wouldn't leave: what else am I putting into my body every single day without thinking about it?
The Microplastic
Reckoning
The research started casually — one study led to another. Conventional nylon toothbrush bristles shed microplastic particles with every brush. Twice a day, 730 times a year, microscopic fragments of synthetic polymer were being released directly onto the mucosa — one of the body's most permeable and absorbent surfaces.
Once in the bloodstream, microplastics accumulate in tissue. Studies have linked chronic microplastic exposure to gut microbiome disruption, oxidative stress, hormonal interference, and neurological inflammation — the exact constellation of symptoms our founder had been living with for years.
The toothbrush. Twice a day. For their entire life. It had never once occurred to question it.
"Twice a day, every day — and nobody was talking about what those bristles were leaving behind."
The Founder
Building a
Clean Household
The decision came quickly once the research was clear: everything in the bathroom that touched the body daily needed to be reconsidered. The natural brands were well-intentioned but incomplete — their formulations were clean, but their brushes were still nylon. Their handles were still plastic. The synthetic fiber problem hadn't been solved; it had just been decorated with better marketing.
What our founder wanted didn't exist in the market — a toothbrush built entirely without compromise. Biodegradable handle. Natural bristles that cleaned deeply without shedding polymer into the mouth. Something that belonged in a clean home the same way a clean diet or a clean water supply does.
So the decision was made to build it.
No Corners
Skipped
Developing the Cetemps brush took time. There are no shortcuts in sourcing natural boar bristle at the quality needed for daily dental use — the taper, the density, the antimicrobial properties of the natural keratin structure — and pairing it with a BPA-free polycarbonate handle that is genuinely durable in a wet environment and built to last.
Every element was sourced with the same scrutiny applied to the toothpaste formula. Hydroxyapatite for enamel remineralisation. Activated charcoal for toxin removal. Cold-pressed coconut oil for its antimicrobial action against the bacteria that cause decay and gum disease. No fluoride. No SLS. No synthetic binders. Every ingredient traceable.
The result is not a wellness gimmick. It is what a toothbrush should have always been — functional, clean, and honest about what it puts in your body every time you use it.
Times per year the average person brushes — every one of those is a moment of potential exposure with conventional nylon

Traceable ingredients across toothpaste and brush. We know where everything comes from. You should too.
The Cetemps Standard
Every ingredient has an origin, a supplier, and a reason to be in the formula. We publish what we use and why. No hidden additives, no filler compounds labelled as "fragrance."
We do not make ingredient decisions based on margin. Hydroxyapatite costs more than fluoride. Boar bristle costs more than nylon. We chose the better material regardless, and we always will.
Cetemps is not a product line. It is a position — that the things you do every day, twice a day, deserve the same scrutiny as what you eat, drink, and breathe. We built the brand we needed to exist.
