5 substances we don't use.
The Kid's Boar Bristle Bamboo Toothbrush is free from Nylon-6 bristles, Epoxy and hot-melt adhesives, Synthetic flavour coatings and Brightly coloured plastic handles and 1 other substances. Each exclusion is explained below with the reason.
Nylon-6 bristles
Even kids’ brushes marketed as ‘natural’ or ‘eco’ almost always use nylon bristles — the ‘bamboo’ part is just the handle. They still shed microplastic particles during brushing (Napper & Thompson, 2016). Children ingest roughly 30% of what’s in their mouths during brushing (Naccache et al., 1992). Natural boar bristles instead.
Epoxy and hot-melt adhesives
The same six adhesive chemistries used in adult bamboo brushes — epoxy resin, polyurethane, EVA, polyamide, PUR, SIS. Even kids’ brands that say ‘chemical-free’ on the box almost never disclose what’s holding the bristles in. Pressure-fitted construction eliminates them entirely.
Synthetic flavour coatings
Some children’s brushes add bubblegum or mint flavour coatings to bristles. Even brands that say ‘natural flavour’ are typically using synthetic blends behind a regulatory loophole — the actual ingredients are almost never disclosed on packaging. Ours are unflavoured.
Brightly coloured plastic handles
Kids’ brushes are often coloured with phthalate plasticizers and cadmium or lead pigments to appeal to children. Uncoated bamboo — no dyes, no pigments.
BPA / BPS / BPF
No plastic anywhere. BPA detected in 93% of urine samples across ages — children show higher exposure relative to body weight (Calafat et al., 2008).

Getting started.
Wet the bristles
Warm water, a few seconds. Natural bristles soften slightly when wet — that's what you want.
Use a pea-sized amount of toothpaste
Less is more for kids. Any child-safe toothpaste works.
Brush for 2 minutes
Gentle circles. Supervise children under 6 — they tend to scrub too hard. The soft bristles help prevent damage even if they do.
Rinse and store upright
Shake off water, stand in a holder. Don't let it sit in a cup of water — bamboo needs to air dry.
The first 8–12 weeks.
Getting used to it
Kids might comment that it feels different from plastic. The handle is lighter, the bristles are softer. There may be a few loose strands on first use — run the bristles under water against your palm to clear any frays before brushing. This is normal with natural hair and settles after the first couple of uses. Most kids adjust within a few days.
It's just their toothbrush now
They've stopped thinking about it. The bristles have shaped to their brushing style. The bamboo handle may have darkened a bit — totally normal.
Time for a new one
Same as any toothbrush. When the bristles splay, swap it out. Kids tend to go through brushes a bit faster than adults. The subscription handles this automatically.
6 questions answered.
Children ingest roughly 30% of what enters their mouths during brushing (Naccache et al., 1992). That makes the bristle material and adhesive more important for kids than adults. Most children’s brushes use nylon bristles attached with epoxy resin — the same synthetic materials as adult brushes, just smaller. This brush uses natural bristles with zero adhesive, so nothing synthetic contacts their gums.
Designed for children aged 3 and above. Younger children should use under supervision.
Boar bristles are softer than nylon — gentler on developing gums and enamel. If your child has specific dental concerns, consult their dentist.
Smaller brush head, shorter handle, same materials and adhesive-free construction.
Not recommended for under-3s without supervision. The brush head is designed for children 3+.
It’s bamboo and boar bristle — natural materials, no plastics, no adhesives. But it’s designed for brushing, not chewing.

Marine Pollution Bulletin
Synthetic polymer fibres, including nylon-6 (the standard material in toothbrush bristles), shed microplastic particles during mechanical action. Natural keratin fibres do not. The difference is structural: extruded polymers fragment; protein fibres decompose biologically. Children who brush with nylon bristles and ingest around 30% of what enters their mouths are ingesting trace microplastic particles.
