This feels like the toothbrush I’ll be quietly happy I bought.

L1 Next | Green by design.


A thoughtful fusion of durable alloy, renewable plant-based heads, and castor-oil bristles creates a toothbrush that’s as good for your values as it is for your smile. Designed to last, designed to reduce waste, designed to make everyday care something you can feel proud of.
This isn’t just better brushing — it’s better living.

The Key Ingredients Behind Our PLA Brush Heads

Our L1 Next brush heads are made using PLA — a bio-based material derived from renewable plant sources such as corn starch and cassava.

The bristles are produced from castor oil, chosen for its flexibility, durability, and comfort for everyday brushing.
