    Why Lightside

    What you get with Lightside.

    Zero Nylon. Zero Plastic.

    Most bamboo toothbrushes still use nylon bristles. Lightside uses natural horsehair. Plastic-free at both ends.

    No PFAS. No Forever Chemicals.

    PFAS are built not to break down, so they build up in the environment and in people. Lightside has none.

    No Glue. No Epoxy. No Bisphenols.

    Bristles are mechanically anchored into the bamboo. No adhesive, no BPA, BPF or BPS.

    Natural Horsehair. Not Boar. Not Synthetic.

    Softer than boar, and nothing synthetic on your teeth. Keratin fibre from root to tip.

    100% Biodegradable

    Handle, bristles, packaging. Compost the whole thing when you’re done.

    Sterilised, Not Bleached

    No bleach involved.

    Shipping & Sourcing

    Bear with us. We’re bringing stock to Australia.

    We’re an Australian owned brand still in our early days. Right now every brush is sent directly from our manufacturing partner to your door, and we’re working toward holding stock here at home to bring delivery times down considerably.

    Free Shipping

    Shipping direct from our maker means we absorb the freight instead of adding it to your cart.

    7 to 15 Days

    Standard delivery from dispatch. Tracking can sit quiet for a stretch while your parcel is in transit. That’s normal.

    Fully Insured

    Every order is covered end to end. If something goes wrong in transit, we make it right.

    Why it takes a little longer

    A local warehouse would mean holding stock, and passing that cost on to you. Domestic freight alone would add around $11 to every order. We’d rather keep shipping free and be upfront about the trade off: your brush takes a little longer to arrive. That’s the deal, and we think it’s a fair one while we grow.

    Thanks for backing a small brand early.

    FAQ

    Answering all your questions.

    Yes. Most toothbrushes, bamboo ones included, still use nylon bristles, and nylon is plastic. Castor bean “bioplastic” bristles are nylon too, just made from plant oil. Watch out for greenwashing.

    Lightside uses horsehair bristles, a natural keratin fibre that is fully biodegradable, with no synthetic polymers and no adhesive. Plastic-free everywhere that matters.

    Boar bristle is the most common natural alternative, and it’s thicker and stiffer. Horsehair is finer and softer than boar, and holds its shape well through daily use. Both were used for centuries before nylon.
    Yes. Horsehair is a keratin fibre, the same protein family as your own hair and nails. There’s no nylon in the bristle, so there’s no plastic to wear off as you brush. Natural bristle was the standard for centuries before nylon arrived in 1938.
    Soft to medium, suitable for everyday use on teeth and gums. As with any toothbrush, gentle strokes at a 45 degree angle beat aggressive scrubbing.
    Roughly 2 to 3 months with daily use, in line with standard toothbrush replacement guidelines. Natural bristles show wear over time, and that’s your signal to replace it. Rinse it and dry it well to get the most out of it.
    Yes. Bamboo handle, horsehair bristles, no synthetic adhesives or nylon components. The entire brush can be composted at end of life.
    Rinse thoroughly after use and store upright somewhere dry. Don’t leave it sitting in water: natural bristles like to dry out between uses, just like any natural fibre. It sounds odd, but a quick blast with a hair dryer after rinsing helps keep moisture and mould away. That’s how you know it’s really natural. It needs a little love 💚
    The soft to medium horsehair bristles are generally well tolerated. If you have diagnosed gum sensitivity or recession, check with your dentist first, as you would with any toothbrush change. Technique always comes before the brush itself.
    No. Horsehair is an animal fibre. We’d rather say that plainly than sell you nylon labelled “plant-based”.

    Care Guide

    How to look after your brush.

    Natural bristles last well with a little routine care. It takes under a minute a day. Here’s everything you need to know.

    1. Rinse thoroughly after brushing

      Rinse the head under warm running water and rub the bristles gently with your thumb to clear out any remaining toothpaste and debris.

    2. Dry the bristles

      Shake off excess water, then give the head about 20 seconds with a hairdryer on a cool setting. Natural bristles hold moisture longer than plastic ones, and keeping them dry is the best way to keep the brush fresh and extend its life.

    3. Store it upright in open air

      Keep the brush head-up in a cup or holder where air can circulate. Avoid sealing it in a cap or travel case while it’s still damp.

    4. Keep brush heads apart

      If it shares a holder with other brushes, make sure the heads aren’t touching.

    5. Store it away from the toilet

      Keep it out of splash range, and close the lid before flushing.

    6. Replace it every 2 to 3 months

      Swap it out when the bristles begin to splay, as you would with any toothbrush. The whole brush, handle and bristles, can go in your home compost.

    Why drying matters

    Our bristles are 100% natural, with no plastics or chemical treatments. That’s what makes the brush compostable, but it also means there’s nothing artificial keeping moisture at bay, so a quick dry after brushing does that job instead.
